Regarding stock and UniBIOS switching.
If UniBIOS file "uni-bios.rom" is found, UniBIOS will be used. If not, it will use stock BIOS (sp-s2.sp1 -> MVS, neo-epo.sp1 -> AES).
In order to switch between them, I made a small shell script. This can be executed in the system menu with the joypad. Each time you run it, it will switch to the other BIOS.
Code: Select all
if [ -f uni-bios.rom ]; then
echo Disabling Universe BIOS
mv uni-bios.rom uni-bios.rom.inactive
echo Enabling Universe BIOS
mv uni-bios.rom.inactive uni-bios.rom
I saved it as "_neogeo_switch_bios.sh" in the linux directory.
Please note, my Neo Geo directory is in lower case (cd /media/fat/neogeo). Pls change it according to your exact directory name.
