Help Changing Neo Geo Bios
-
I'm having some trouble with the Neo Geo bios.
I go into the quick menu and change the bios to universe bios restart whatever game it is I'm playing and it's still booting with the initial bios.
No matter what I do it seems to be the North American bios. I need some help here or I'll never get bouncy Mai back.

Sorry, heat of frustration.
Pi 3
Retropie 4.2
Neo Geo Roms are in the Neo Geo FolderMy issue is whenever I try to change the Neo Geo Bios in the Retroarch menu it doesn't change even after I restart the rom.
I assume I can fix this if I rename the Universe bios to whatever the default is. Or maybe there's another way? -
@popetherevxxviii This is what worked for me
- Make sure your
neogeo.zip
(or your ROM zip) file contains the UNIBIOS necessary files:
$ zipinfo neogeo.zip | grep uni -rw---- 0.0 fat 131072 b- defX 96-Dec-24 23:32 uni-bios_1_0.rom -rw---- 0.0 fat 131072 b- defX 96-Dec-24 23:32 uni-bios_1_1.rom -rw---- 0.0 fat 131072 b- defX 96-Dec-24 23:32 uni-bios_1_2.rom -rw---- 0.0 fat 131072 b- defX 96-Dec-24 23:32 uni-bios_1_2o.rom -rw---- 0.0 fat 131072 b- defX 96-Dec-24 23:32 uni-bios_1_3.rom -rw---- 0.0 fat 131072 b- defX 96-Dec-24 23:32 uni-bios_2_0.rom -rw---- 0.0 fat 131072 b- defX 96-Dec-24 23:32 uni-bios_2_1.rom -rw---- 0.0 fat 131072 b- defX 96-Dec-24 23:32 uni-bios_2_2.rom -rw---- 0.0 fat 131072 b- defX 96-Dec-24 23:32 uni-bios_2_3.rom -rw---- 0.0 fat 131072 b- defX 96-Dec-24 23:32 uni-bios_2_3o.rom -rw---- 0.0 fat 131072 b- defX 96-Dec-24 23:32 uni-bios_3_0.rom -rw---- 0.0 fat 131072 b- defX 96-Dec-24 23:32 uni-bios_3_1.rom -rw---- 0.0 fat 131072 b- defX 96-Dec-24 23:32 uni-bios_3_2.rom
- Launch the game, then go to Retroarch GUI via
Select + X
, go toQuick Menu
, then inOptions
, change the 2 settings:- Neo Geo Mode - set it to
UNIBIOS
- BIOS - set it
Universe Bios ver. 3.2
. This would load the uni-bios_3_2.rom file from either theneogeo.zip
bios file or from the ROM archive.
- Neo Geo Mode - set it to
This should do it - tested on a RetroPie installation upgraded from 4.2.2 to the latest.
EDIT: Managed to get my 1st screenshot on the PI with the 2 RA settings:

AH I see exactly what I did wrong, I need to set the neo geo mode to unibios as well.
Lets see if this fixes things.
