Question Preload entire rom into memory
Posted by: Styrixa - 06-03-2019, 03:11 PM - Forum: General - Replies (1)

Hi All,

I'm new to the forum, and I searched, but couldn't find the answer. I apologize if this is covered somewhere obvious.

What exactly does "preload entire rom into memory" do? I know, in theory, what it is doing, but what effect would this have on performance and energy use? I often run emulators on my laptop, and I try to reduce battery use, and try to keep my computer cool. It is actually something I really appreciate about mGBA, as opposed to some other emulators.

I work on ROM hacking as a hobby, and am curious if enabling this feature has an adverse (or positive) effects on patched ROMs. I assume it wouldn't have any effect.

Generally, I assume this would improve performance if a computer has enough Ram, but I'm not exactly sure. I know a bit about how computers work, but I use hacking ROMs and Emulation as a way to educate myself, so please be gentle. Wink

I currently use a 2010 MacBook with 8 GB ram and 256 MB video ram. Right now, MGBA seems to work fine at tops speeds, even in fast-forward.

Any help would be greatly appreciated.

  My roms doesn't load [please help]
Posted by: darioeslaonda - 06-02-2019, 05:05 AM - Forum: General - Replies (4)

I have the latest version 0.7.2 I have my roms associated with the emulator, every time I try to start one directly from the rom, it only opens the emulator but never starts. I already tried all the configurations and I already installed all the versions and it's always the same. If I start the game directly from the rom, it only opens the emulator but does not start the game. If I open it directly from the emulator it runs without problems but I can not use it with Launchbox. Thank you very much for your help.

  Not able to configure controls with libmgba on linux.
Posted by: Nonokat - 05-30-2019, 02:05 PM - Forum: General - Replies (1)

Hey,

I am on Manjaro Linux and I downloaded libmgba to start mgba from command line.
So far everything works well and as expected, I am able to set the size of the output window etc,
but I can't seem to make changes to the controls.

For example I would like to change the b key because i don't use an American keyboard.
The mgba manual tells me that mgba reads the config file $XDG_CONFIG_HOME/mgba/config.in ,
but there is no file there and I didn't know how the configurable variables would be named.

The file did appear though after installing mgba-qt and with mgba-qt I was able to change the controls
over the gui, but I would rather use mgba from command line without gui, because in i3wm there are
window size issues. The problem is that the mgba command line version doesn't seem to read the config file
at all.

I already tried to use the -C flag to change the b key like so: mgba -C keyB=89, but that didn't work either.
Other things like -C volume=5 worked fine.

Do you have any idea, how i could change the b key?

Thanks in advance!

  Tiny text in mGBA settings menu.
Posted by: RichterEX2 - 05-28-2019, 10:33 AM - Forum: General - No Replies

I'm getting a very bizarre bug when I try to load the settings menu. The text on the right side is way too small to read! Any idea how I can fix this?

[Image: 0bed527359b160100276709a553aadd5.png]


Updated: Okay, I fixed it this one myself. I had my 1440p monitor set as my main, which gives me small text to begin with, but moving it over to my 1080p screen kept the text tiny and horribly scaled. Setting the 1080p as my main display set the text back to a normal, readable level. Definitely an odd issue though.

  Compile 7.2
Posted by: Amnesia1000 - 05-27-2019, 06:18 PM - Forum: Development - Replies (4)

Again I, when giving me error the last builds compiled by me (as I explained in the forum "General" the 8.0 builds do not start), I want to see if version 7.2 would work for me or not. How can I compile version 7.2 and not the git version? Which command to compile a specific branch, or just version 7.2

  Problem with o3DS XL
Posted by: RaCuGa - 05-27-2019, 05:28 PM - Forum: General - Replies (3)

Hi,
I'm trying to use this emu to play my old GBA backups, but I have a problem with the Emu:
Everytime I open it it shows only a Black Screen... The lower screen only shows the white-triangle that selects teh archives, and also the screen shows the battery icon... nothing more. (if you need would upload a cap, but... it shows only that XD)
Is like the words were in black, as teh background... I can open folders, roms... but not the Options (pressing X) 'cause it leaves me to the HomeScreen.

I'm using LUMA 9.1, B9S, o3DS XL, using only Sysnand.
I have this same problem with other SD.
The Emu doesn't create any "config.ini", so I haven't edited anything.
Using the last mGBA version 7.2, the .CIA version. Had the same problems with 7.1.

  mGBA does not start
Posted by: Amnesia1000 - 05-27-2019, 06:33 AM - Forum: General - Replies (1)

First of all forgive me if this post does not go in this section, I was going to post it in Development but it is not sure.

My problem is that when I try to start the emulator, it doesn't start. It starts from the terminal and I get this.

"[amnesia@manjaro mgba]$ ./mgba-qt
KCrash: crashing... crashRecursionCounter = 2
KCrash: Application Name = mgba-qt path = /media/amnesia/Games/.Emulators/mgba pid = 11151
KCrash: Arguments: /media/amnesia/Games/.Emulators/mgba/mgba-qt
KCrash: Attempting to start /usr/lib/drkonqi from kdeinit
sock_file=/run/user/1000/kdeinit5__0

[1]+ Stopped ./mgba-qt"

This is the GIT version compiled by me, but the compilation does not give error, so I guess the compilation is not the problem.

I wouldn't know which version doesn't work for me since I haven't used the emulator lately, but I always keep it updated from git.

I am on Linux Manjaro.

  Messed up controller + changing palettes?
Posted by: ddubs - 05-25-2019, 07:18 AM - Forum: General - No Replies

I joined the mGBA forums just so I could get some help.

I'm playing mGBA through Steam and with a Switch Pro Controller, but the mappings keep messing up every time I close the settings. UP no longer works and LEFT becomes A. The same thing happens when I use either an Xbox One controller or a DS4 Controller.

Also, how do you change palettes? Is that a feature? I found old forum posts where admins said they were working on it, but that was 2 years ago. I can change the default palette, but I can't save or load palettes.

  Metroid: Zero Mission (Randomized) crash
Posted by: Nicholas Steel - 05-22-2019, 06:28 PM - Forum: General - No Replies

Required:
Randomizer program (download link in the first post): http://forum.metroidconstruction.com/ind...559.0.html
mGBA v0.7.1: http://mgba.io/downloads.html
Metroid: Zero Mission (USA)
Gameboy Advance BIOS

The game it self seemingly crashed right here https://imgur.com/a/dX6bufT without crashing the program. I double checked that I didn't accidentally toggle Pause. This was about 10 to 15 minutes after making the transition from VisualBoyAdvance M to mGBA 0.7.1

Also annoyingly the Emulator doesn't log a bunch of stuff by default so when I go to view logs... it's an empty window.


Rewinding emulation allows me to continue... thankfully.

I just now noticed that going in to the Settings causes the Log Viewer to reset its configuration... (the tick boxes on the left change)

  Screenshot Button Issues
Posted by: BlueberryPancakes - 05-15-2019, 04:57 PM - Forum: General - Replies (4)

I have been having a problem with mGBA saving the button that I want to use to take screenshots. Originally it was set to F12, but using it only adjusted the brightness of my laptop screen. I changed it to the + button instead, but every time I close mGBA out, it doesn't map the screenshot command to any button so I have to set my preference again when I reopen it.

Is there any way that I can prevent having to set this up every time I reopen the game?
