gpSP not working

[lunorian]

I followed the tutorial at viewtopic.php?f=78&t=37433&start=50 and I'm still unable to get the games to play. It hangs at the gameboy splashscreen. I downloaded game_config.txt from the GitHub repo and created gpsp-input.cfg from another thread I found on this forum (I did basic googling before asking here).

The following files are in the folder:

Code: Select all

game_config.txt  gpsp            Pokemon - Emerald Version (U).gba
gba_bios.bin     gpsp_input.cfg  romdir.txt

When trying to play a game I get this error:

Code: Select all

pi@raspberrypi:~/Documents/gba $ ./gpsp
audio: freq 22050, size 4096
game config missing
ALSA lib pcm.c:7843:(snd_pcm_recover) underrun occurred

Any idea how I can get this working?

Ok so apparently I'm a complete idiot, I've been selecting GBA BIOs and not the rom. Now I have another issue. The arrow keys and start works fine, however pressing the A Button (z) has a huge lag. My keyboard input is over VNC although using a monitor so I can see the game in real time. The attempted ROM is Pokemon Emerald, I'd really like to be able to play although the A Button barely works. Any ideas on fixing this?
