  Romhacks targeting VBA-M: Accuracy vs (bug-for-bug) "Compatibility"
Posted by: jimbo1qaz - 08-14-2018, 08:38 AM - Forum: General - Replies (1)

I'm new to GBA romhacking, and my first impressions are absolutely negative. I tried downloading the Moemon romhack (please don't judge my tastes), but it crashes after the intro screen on mGBA.

I kinda made an unpleasant first impression in their Discord server, complaining about their usage of IPS patches (inability to tell which revision to use), and incompatibility with mGBA (and likely hardware). They complained I hadn't read the readme, which specified the ROM name (which doesn't help) and CRC32 (facepalm, it's a horrible and insecure checksum) to use.

In the project Discord, one user specified this:

Quote:Until mGBA is completed, it's still and experimental emu
Compatibility=Ability to play every title and rom hack without crashing or bugging
Which mGBA haven't
In response to me arguing that:
Quote:"bug-compatibility with vba-m = Ability to play every rom hack which doesn't work on hardware"
"compatibility = behaving like real hardware"
they responded:
Quote:Do what you want, but you're still wrong
Behaving like real hardware is not conpatibility
It's emulation
A good emulator is able to work like real.hardware
And a compatible emulator can do both work like real hadware and go out of the way to work like a slighty different one
and a good vba-m workalike supports anything that runs on vba-m. that's not a compatible emulator, merely one broken in the same ways
Quote:i wont stat a pointless argument about emulators. We use VBA-M as a base and that's it. We won't debug or support other emulators

I assume, given the Holy Grail articles and discussion on byuu's forum, that mGBA is the most accurate emulator, and that  Higan is second but slow. I'm assuming that hacks that break on mGBA are broken on hardware, so they're making a VBA-M game, not a GBA game. Are my assumptions correct? Having to deal with this kind of mindset is frustrating.

----------

Additionally are there any ways to detect VBA-M in GBA mode, and display a "only tested on VBA" warning when running on other emulators? I brought this up, the community mocked me and demanded me to "show them how". Echo RAM? VRAM locking? Are these GB-specific?

  Need help with hacked Pokemon Rom not working
Posted by: Fuey - 08-04-2018, 10:20 AM - Forum: General - No Replies

I am trying to to play the Nameless Fire Red Rom. The game work on vba-(m) emulator but for some reason that emulator has massive frame drops and de sync problems on my mac. Usually after starting up the rom on mGBA the game crashes right before professor Oak is supposed to show up and set you on your journey, so I get the title screen and everything.

I got the game working but loading a .sav file that I had from the other emulator but during the first battle the game crashes giving me the Jumped to invalid address: 09FE209C error. Any help would be appreciated.

  New 3DS Rewind and Turbo
Posted by: Jacktendo - 07-25-2018, 11:09 PM - Forum: General - No Replies

Hi I just got the mGBA emulator for the New 3DS Xl, and I was wondering if there is a way to rewind and/or if there is a turbo mode? It would really help with the game I'm playing. Thanks in advance (no pun intended)!

  Issues with Legacy of Goku 2 on PS Vita
Posted by: vu.anguyen176 - 07-23-2018, 01:25 PM - Forum: General - No Replies

Hi guys,

I successfully installed mGBA on my Vita. However, as I tried to play Legacy of Goku 2, the game said “it could not run on this hardware” when Gohan approached the world map fly. I wonder how I can fix this issue.

  Change emu menu background
Posted by: Duhjoker - 07-23-2018, 08:26 AM - Forum: Development - Replies (1)

Hi guys

   I was wondering if there was a way to change the menu screen settings inside the emulator. The black background in menu is ok but i would like to add a custom wallpaper or color change. Ive been looking at the srm, xml files and what ever and i can change the live area and its png’s but i cant see anything that would let me give the menu a wallpaper. 

 Is this possible? If so can you please point me in the right direction on how to do so?

Im running the latest MGBA version on a vita with FW3.67 and henkaku.

  printing debug strings from inside a game
Posted by: tshirtwearingdork - 07-19-2018, 09:22 PM - Forum: General - No Replies

Hi, 

  I have been toying with some GBA development and experimenting with different emulators. I've managed to get mGBA set up using GDB and Visual Studio to give me some decent line by line debugging of my C code. But I'd really like to know more about this feature that's mentioned on the main page "GBA: Support printing debug strings from inside a game" and if there's any instructions on how to get this functionality working using ASM or C.

Other than this, mGBA is really nice to use for GBA development so thanks, and the inclusion of GDB hooks is brilliant.

So I'm installing the .cia on my emunand (11.7U), run the app, it brings up the menu so I navigate to a rom file (tried many), and when I select it I just get a "Loading" message that seems to freeze. Anyone have any experience with this and know how to fix it?
