Homebrew CitrAGB - 3DS GBA Emulator (WIP)

[Shadowtrance]

Where's the .smdh file? I don't like having homebrew applications that don't have a smdh file. I can make one for you if yoy want.

There's one in the rar i put in the post above yours that i just compiled from source, or you could compile it yourself. Either or.

Yeah I get a cut in half black screen

Yeah i get that too. Bugs are half the fun though!

I'm gonna try this now. I'm also gonna make a video of it.

Alright, pushed the font fix to my Github. I'll probably add the proper smdh stuff soon. Just as a note, this does in fact rely on the latest version of ctrulib since it uses the RGB5A1 screen buffer and has a few other things set in with double buffering.

This does not work for me. I didn't read many posts above this one so idk if others got this problem. It makes the screen grey and it crashes to the home menu after like 2 seconds.

Figured it out, I completely forgot that gpsp requires a GBA bios to run, and apparently the error which makes you aware that it's missing causes a crash. Just add gba_bios.bin to the root of your SD and it should work.

Where do I get gba_bios.bin?

edit: i found one already on my pc lol

Google

The same way you'd get a ROM. Either dump it yourself or find it on the interwebs. Just google GBA Bios bin and you'll find it, it's needed for gpsp so it's not the hardest thing to find.

I remember there are 2 versions of the GBA bios. Only one of them worked well for the PS2 port of gpsp.

Whenever I navigate to a directory, it crashes and returns me to the home menu.

From the source code

          debug_screen_printl("Sorry, but gpSP requires a Gameboy Advance BIOS      ");
          debug_screen_printl("image to run correctly. Make sure to get an          ");
          debug_screen_printl("authentic one, it'll be exactly 16384 bytes large    ");
          debug_screen_printl("and should have the following md5sum value:          ");
          debug_screen_printl("                                                      ");
          debug_screen_printl("a860e8c0b6d573d191e4ec7db1b1e4f6                      ");
          debug_screen_printl("                                                      ");
          debug_screen_printl("When you do get it name it gba_bios.bin and put it    ");
          debug_screen_printl("in sdmc:/gba/ .                                      ");
          debug_screen_printl("                                                      ");
          debug_screen_printl("Press any button to exit.                            ");

So use that md5sum to check you have the right version

• Games stored in folders currently do not work, this will be fixed soon.

Managed to get it to work yay , however it's very slow and glitchy when playing pokemon fire red. However it's definitely nice to know that this being worked on! best of luck

 

[ChrisRX]

Metroid Zero mission crashes after a few seconds but it's great to see it up and running. Keep up the good work.

 

[shinyquagsire23]

Fixed the nagging message for gba_bios.bin, so it shouldn't just crash without a bios binary. Will probably work on loading files from directories next and maybe fiddle with some video stuff.

Crashes 3DS when opening, even with the one that someone posted before in a rar file

Redownload from the main post, it should be fixed. If it crashes on opening it's outdated, it should notify you that you're missing gba_bios.bin. If you don't already have gba_bios.bin, find it and put it at the root of your SD card.

Yeah i just saw that and now it loaded. Except when I tried to run rhythm heaven it crashed D:

EDIT: 2nd time it worked. I think I may have opened the bios file by accident

Does this support most gba games? Will duke nukem advance work?

Basically anything that gpsp can run, this (should) run. So maybe, maybe not. Testing is definitely appreciated so that I can find issues with my porting and fix those to get back to gpsp's true compatability.

Also, I just pushed a new 3dsx. This one reverts the previous method I used to rotate the screen and instead writes to a GBA framebuffer, and then uses this framebuffer and translates it over to the screen via software. In the future I'll probably map this buffer to a texture and render it in hardware instead. However, this fixes a number of graphics-related crashes, which is good. I also fixed input, so you'll be able to progress a lot more now in games and further testing.
