  Games do not automatically boot
Posted by: fox_whisper85 - 06-27-2015, 04:48 PM - Forum: General - Replies (5)

I reported an issue here on Github, regarding m-GBA and how ROMs do not automatically boot up upon loading them. I have tried both real BIOS and emulated BIOS modes, skipping the intro, not skipping the intro, and no matter what I do, I have to pause the emulator then resume in order for the ROM to boot up. My issue has been posted here https://github.com/mgba-emu/mgba/issues/48 and I can only hope that eventually, someone looks into it. The versions I tried were 0.21 official and the recent developer builds, neither resolve this issue, and no one else can seem to reproduce it. Would it help if I captured video of it with nVidia Shadowplay and upload it to YouTube to show what I'm talking about? I'm very baffled here and I want to enjoy this emulator even more, I just don't know why the games don't boot up automatically.

  Game Boy Advance Test Suite
Posted by: endrift - 06-26-2015, 12:37 AM - Forum: Development - Replies (16)

In the interest of furthering the state of Game Boy Advance emulation, I've been writing a test suite that tests various aspects of hardware. At the moment, it only tests timing operations, but way more will be coming in the future. Source code is available on GitHub.

Memory tests
Each test contains 44 configurations. The current version contains 1552 tests total.


  1. mGBA (master): 1552 passes
  2. higan v107: 1552 passes
  3. mGBA (0.8.0): 1532 passes
  4. NO$GBA 3.0 (BIOS): 1394
  5. VBA-M 2.1.4: 1337 passes
  6. VGBA 5.5: 1255 passes
  7. NO$GBA 2.8e: emulation crashes

I/O read tests
The current version contains 123 tests.
  1. higan v103: 123 passes
  2. NO$GBA 3.0: 122 passes
  3. mGBA (0.8.0): 116 passes
  4. VBA-M 2.1.4: 100 passes
  5. VGBA 5.5: 10 passes

Timing tests
Each test contains 20 (or 10 if only an ARM version is supported) configurations:
  • ROM 4/2 waitstates, no prefetch
  • ROM 4/2 waitstates, prefetch
  • ROM 3/2 waitstates, no prefetch
  • ROM 3/2 waitstates, prefetch
  • ROM 4/1 waitstates, no prefetch
  • ROM 4/1 waitstates, prefetch
  • ROM 3/1 waitstates, no prefetch
  • ROM 3/1 waitstates, prefetch
  • WRAM
The current version contains 1560 tests total.

  1. mGBA (0.8.0, BIOS): 1540 passes
  2. mGBA (0.8.0): 1520 passes
  3. higan v103: 1300 passes
  4. NO$GBA 2.8e: 968 passes
  5. VBA-M 2.1.4: 679 passes
  6. VGBA 5.5: 4 passes
  7. NO$GBA 3.0 (BIOS): varies

Timer count-up tests
The current version contains 936 tests total.

  1. mGBA (0.8.4, BIOS): 744 passes
  2. mGBA (master, no BIOS): 639 passes
  3. mGBA (0.8.4, no BIOS): 610 passes
  4. VBA-M 2.1.4: 440 passes
  5. NO$GBA 3.0 (BIOS): 172 passes

Timer IRQ tests
Each test contains 10 configurations. The current version contains 90 tests total.

  1. mGBA (0.8.0): 70 passes
  2. higan v107: 36 passes
  3. VBA-M 2.1.4: 8 passes
  4. NO$GBA 3.0: varies

Shifter tests
Each test contains 2 configurations. The current version contains 140 tests total.

  1. NO$GBA 3.0: 140 passes
  2. higan v107: 132 passes
  3. mGBA (0.8.0): 132 passes
  4. VBA-M 2.1.4: 132 passes

Carry instruction tests
Each test contains 3 configurations. The current version contains 93 tests total.

  1. mGBA (0.8.0): 93 passes
  2. higan v103: 93 passes
  3. NO$GBA 3.0: 93 passes
  4. VBA-M 2.1.4: 93 passes

  1. mGBA (0.8.4): 52 passes
  2. NO$GBA 3.0: 52 passes
  3. VBA-M 2.1.4: 52 passes

BIOS math tests
Each test contains 5 cases: the outputs in registers r0 through r3 and the program state flags. Note that for most of these tests, r0 is the only important case, although some games may rely on the other values. The current version contains 625 tests total. These tests only apply to emulators with HLE BIOS.

  1. mGBA (0.8.0): 625 passes
  2. VBA-M 2.1.4: 425 passes
  3. NO$GBA 2.8e: emulator crashes
  4. mGBA (0.5.2): emulator crashes
  5. VGBA 5.5: emulator crashes

DMA tests
The current version contains 1256 tests total.

  1. mGBA (0.8.0): 1232 passes
  2. NO$GBA 3.0: 1060 passes
  3. VBA-M 2.1.4: 1032 passes
  4. VGBA 5.5: 998 passes

  Collection of interesting cheat codes/fixes
Posted by: GH56734 - 05-28-2015, 07:49 PM - Forum: General - Replies (1)

Hopefully as my way to give back something to this emulator, in case it gets support for cheat lists (and maybe patches - something like ips/ups codes to be applied to the rom but included in the cheat list file) to cover some interesting stuff enhancing the emulation experience...

If this is okay, this thread should be a compendium of interesting cheat codes from around the internet covering obscure stuff - mainly codes to enable e-Reader content in Japanese and English versions. It could be really helpful for game releases from regions that never had the codes in question. Also covered would be some other peripherals (including probably ones already emulated by mGBA).

So, here I go Tongue

Super Mario Advance 4: Super Mario Bros 3
PAL version
European regions never had the e-Reader software officially released, but the ROM does include the ability to scan US e-Cards and all e-Reader features fully translated. The fourth option is just... hidden.
A blank PAL save file with the fourth option is available online, but a cheat code could be more useful in our case (especially since people get to keep their old PAL saves this way).

While I couldn't manage to find the "enable flag for file select screen layout including the e-Reader option", I found the next best thing... a code that forces the cursor to select the invisible e-Reader "Level Card" option. Doesn't display the number though like in the US version or the hacked PAL save, and doesn't enable R button (scan switch cards) in main game.
It's a memory code, couldn't convert it to CB format and have it working :/


US version
Codebreaker codes:
Released in US/JP
83002D52 0001 Blue Green Switch (SMB2U vegetables in main game)
83002D52 0040 Orange Switch (fireball kills drop coins)

Released in JP
83002D52 0002 Cyan Switch (1/2 P-Meter)
83002D52 0010 Green Switch (Slows timer for 50 seconds)
83002D52 0100 Yellow Switch (Luigi has flutter jump)
83002D52 0400 Blue Switch (every 1-Up becomes 3-Up)
83002D52 0A00 Red Switch (harder enemy variants, double score)

83002D52 0020 4000 Points Switch (third enemy stomp in a row = 1-Up)
83002D52 0004 1-Up Mushroom Switch (blocks containing 1-Ups give 3-Ups)
83002D52 2000 Double Health Switch (boss HP x 2)
83002D52 1000 Floating Platform Switch (saves from bottomless pits twice)
83002D52 0008 Hold Box Switch (SMW item box with infinite uses)
83002D52 4000 Luigi Demo Switch (Luigi replaces Mario in replays)
83002D52 0080 Two-Hit Switch (Mario always revert to small when hit)

These effects can be combined. For example:
83002D52 2080 = Double Health Switch + Two-Hit Switch

Here's the entire breakdown of what each bit from right to left does for 83002D52 XXXX:
01 = 0001 = BlueGreen (SMB2U vegetables)
02 = 0002 = Cyan (halves P-Meter)
03 = 0004 = Unreleased (1Up blocks > 3Up)
04 = 0008 = Unreleased (SMW Hold Item Box)
05 = 0010 = Green (Slow Timer)
06 = 0020 = Unreleased (4k-Pt Row Jump bonus)
07 = 0040 = ? Orange (Fireball kills drop coins)
08 = 0080 = Unreleased (Costume Mario > small when hit)
09 = 0100 = Yellow (Luigi w/ SMB2 jump)
10 = 0200 = ? (score x 2 for everything, 1/2 Red effect)
11 = 0400 = ? Blue (all 1-Up > 3-Up)
12 = 0800 = ? (harder enemies, 2/2 Red effect)
13 = 1000 = Unreleased (Pit Saver Platform)
14 = 2000 = Unreleased (Boss HP x 2)
15 = 4000 = Unreleased (Luigi in Demos)
16 = 8000 = ? -unknown-

There's more..

Megaman Zero 3
JP version

US version (unreleased)
e-Cards for MMZ3 were never released in the US, and their functionality was eventually restored in the DS port, but the data is still available in the US ROM, fully working and translated. (No idea about PAL rom?)
These are Codebreaker codes:

A few things:
. The cheats work for both U & E versions of BN4.
. Every mod except 103 & 104 can be assigned to any value; They don't have to be assigned to their official values.
. Blue Moon soul unison mods work in Red Sun and vice versa.

US version
Localized versions butchered lots of content from main game to meet draconian cartridge space limits, and the crossover Boktai quest as well as e-Reader content was simply deleted altogether (some story/boss content got integrated in main game). Enabling the e-Cards with cheats will just give broken cards with correct descriptions but which will crash the game/not work.
JP version is more interesting in that regard.

Regarding MBN4, MBN5 and MBN6's e-Reader abilities, there's this project going on covering all of these: http://github.com/Prof9/mmbn-mod-card-kit/releases
No such luck for Battle Chip Gate hardware

Mario vs Donkey Kong 1
Had secret e-Reader support for a bunch of extra rare e-Cards that were given to only 2000 people worldwide as part of a contest. Even then, only 5 levels were actually released. The levels are contained on the rom and are 12 (US)/13 (JP) and different for each region (and besides those there's an extra test level)

US version
The e-Reader level menu can be accessed by changing the value at 034E09C4 from 18 (normal menu) to 1A, and the list of preloaded levels can be accessed by changing it to '1C' after choosing "Add Level". The thirteenth level on the list is a dummy level, probably for testing.

JP version
Same as US version, but the levels are different? Trying the above method displays two menus for scanning e-Cards and preloaded levels, but I can't figure out how to actually access those.

Hi there Smile

Really pleased with how open you are with feedback, and seeing as this may be the de-facto portable GBA emulator down in the future, I figured I might want to elaborate a bit on my.. wish list of stuff I'd really, really love to find in the game Tongue

So, without further ado, here I go Tongue

Color Correction

The older GBA models lacked back-lighting, hence why some games tended to overcompensate with altering their palettes to look far brighter than needed. As later models included back-lighting, some games disregarded this.
It would be lovely to have some custom palette correction options, kind of like with NES palettes.

SAPPY Sound Emulation Enhancements

GBA sound output is, bluntly put, often horrible. Sound gets processed through the CPU, and in most games it just tends to get the shorter end of the stick.
That aside, for games that do get the sound processed to the full potential of the hardware, the sound quality is full of crackling and noise, kind of like how sound gets distorted through phones.

While some games rely on chiptunes/GB sounds (Starfy 1, Castlevania HoD, Super Robot Taisen J), or the internal sound samples themselves have a very low bitrate to save ROM space (Lunar), ... in most cases, the sound samples found within the ROM are much higher quality than what gets output.

I often used this tool "GBA Music Ripper". It's a bit of a work-in-progress, and there are bugs at times (having to do with some instruments not being figured out, or in the case of both Golden Sun games not at all due to them using a different sappy format with reverb and stuff like that).

However, the sappy format is really widespread and almost universal in GBA games, and this tool takes the rom and rips all music, voice samples and sound effects, in sets of SoundFont files (.sf2) and midi files (midi). Using a tool like foobar to read the soundtrack, even Mother 3, often cited as a highlight of sound engineering in the GBA, pales compared to the ripped version which sounds like from a DS game. Zelda Minish Cap is a delight.

So, what I'm asking for is...

This reminded me a huge lot of 3D models rendering in shit resolutions... then emulators added upscale options to process the game's assembly instructions for graphic displaying (in our case it would be sound emulation) as normal, then recognizing specific calls to graphic hardware (here sound hardware, or just sappy sound engine assembly instructions), overriding them when it comes to end-user output to show a custom higher quality model/sound output done in real time.

Would this be possible here? I have the feeling this would be the biggest drawing point to this emulator if this ever materialized.

Debugger Suite

To help fan-translators and such folks.

Well, for starters we'd need some basic stuff, namely:
1/ Cheat support (we have already a really good base work, besides editing/deleting cheats it would also need external cheat files)
2/ Powerful cheat search engine (relative search with ability to set initial values, searching specific value, searching value equal to a given address, displaying values signed/unsigned/hex), and options for bigger/lower/equal... should be assigned to hotkeys in-game with HUD optionally displaying and telling how many results are there.
3/ Search for ranges of unused memory addresses throughout the game that never get written to aside from instructions blanking whole memory, could be running in the background as we play.
Useful for translators to find where to stuff their custom code.
4/ Save States, Rewinding, Frame Advance, Pause key, Reset key

With that out of the way:
1/ VRAM viewer (with ability to switch between various GBA modes)
2/ Map viewer (with ability to see what each square from each BG is from)
3/ OAM viewer (with info like rotation/palette/etc, palette viewer and exporter to same format as VBA, )
4/ Hex viewer/editor (divided by memory types ROM/VRAM/SRAM/...) and the ability to extract a specific range to an external file, pick a custom table (tbl) to change what each hex byte displays as as a letter/char in the right column (ascii, shift-jis, given by default, with option to get an external tbl file)

5/ you can drag to select a given area in either hex viewer or map/vram viewer, then
a: copy it to the clipboard (for VRAM: as a bitmap, for HEX: depending if it's the letter area or the hex area, as a string of characters/hex bytes selected in raw text)
b: paste with overwriting from the first byte onwards, byte number gets unchanged
c: track from ROM : meaning, relying on the rewind feature, tracking where this byte originated from in the ROM - either until a MOV instruction of a block of stuff from the rom, an LZ/Huffman compression scheme or just displaying the instruction that generated it the instant we reach a dead-end.
Figuring out where stuff is in the ROM is the bane of translators Tongue
d: watch value for RAM addresses. Like with SNES9X, it can show a tiny HUD with the value real time in-game. Could be useful too if available in the cheat engine

Of course, there's the debugger:
1/ Disassembler
2/ All Breakpoint options (on write, on read, on execute, run, break...) with keyboard shortcuts too Big Grin
3/ A good status viewer of various hardware flags
4/ Tracer (just dumps all instructions executed between instants t1 and t2)
5/ Assembler (like with FCEUX)

Unemulated Stuff

* Various rumble features: GB Player Rumble, Drill Dozer variable Rumble, WarioWare Rumble...
could use smartphone rumble, joypad rumble, wiimote rumble, or alternatively just a colored HUD square (that turns orange, or shades of orange/yellow/red for Drill Dozer's variable speed rumble)

* Key mapping for gyro controls in Yoshi/WarioWare with various schemes - key inputs with four keys, wiimote emulation (better), wiimotion plus/gyroscopic smartphones (best). And maybe the screen could rotate too?

* Figurine stuff (LegendZ, among 4 other games, but it's really obscure)

  mGBA compared to MESS
Posted by: geertjan - 05-16-2015, 10:57 AM - Forum: General - Replies (4)

Hi, thanks for pushing GBA emulation to the next level!

I had a question, I noticed MESS implemented some GBA improvements taken from mGBA, which is cool of course, the power of open source.

Now this ConsUME site says that MESS (or UME) "is, in our opinion, at least as good as the best standalone emulators for this system."

Would you agree that MESS and mGBA are on the same level of accuracy/compatibility, or do you think mGBA still has an edge?

  [Linux] Joypad inputs
Posted by: nicodemus - 05-14-2015, 02:06 AM - Forum: General - Replies (2)

Using mgba-qt, the program didn't seem to catch all the inputs from my 360 controller. It recognizes it, but only grabs a few input presses (mostly main joystick, and one trigger.)

Is this a known issue? Can I help troubleshoot in any way?

Thanks so much for doing this! We are in desperate need of a modern emulator built from the ground up. Also thanks for the early Linux support!

Q1) Is there a gui for the linux version? I seem to only have a CLI command. If I have this right you wrote the GUI in QT, that should make it easy to get going under Linux, yes? For reference I'm on Kubuntu 15.04 using the nightly.

Q2) What anti-aliasing process are you using under Windows, and can I use it under Linux? It seems to wash out the colors and smudge the image a bit, but at least it's an option. Smile

Q3) I'm very much looking forward to filters coming to mGBA, as it's one of the big things that makes me choose to emu over standard play. What do you hope to implement and how likely do you think it is for it to make it into version 3?

Q4) When do you expect v3 to release, roughly?

Thanks again for everything! mGBA is now my goto emu as it performs flawlessly for me, while VBAM does not.

  GBA colour emulation
Posted by: angrykaspar - 04-29-2015, 01:19 AM - Forum: General - Replies (2)

A while ago I asked about this in an email, but since there was no reply I assume you missed it. Sorry if you're reading it twice.

Do you have any plans for a colour correction filter? GBA games were oversaturated to compensate for the poor screen of the GBA. I first noticed the issue on Golden Sun 2, which I'd already extensively played on an original GBA and an SP. The game was fine even on the backlit SP, but on an emulator without a desaturation filter, every instance of black appears maroon. VBA-M and No$GBA are the two emulators I can think of with such a filter.

Is this option necessary if you have the emulation synchronized to audio? I would have thought that the emulator would already run at 59.7fps if the audio was running at the right speed.

  ROM hacking tools in mGBA
Posted by: endrift - 04-18-2015, 07:44 PM - Forum: General - Replies (3)

I've gotten a request for a bunch of tools to be added for ROM hacking purposes, including:

  • A palette exporter
  • text translation table support (.tbl?)
  • A way to trace RAM data back to ROM
Are there any other tools that people would want?

As for these tools, what file formats would be useful? For palettes, I could easily do .aco or .act exporting, two Photoshop formats. Are there other formats that would be useful? And what of .tbl files? I don't have any information on this file format, which would make it a bit challenging to implement. I found http://datacrystal.romhacking.net/wiki/Text_Table, but it's a bit incomplete.
