Is there a way in pcsx_rearmed to configure some games to not use the BIOS?
I'm using the 09-29 nightly, and the 7001 bios (tested 5501 and 1001),
-Gran Turismo works fine (in 09-28 crashes)
- in Legend of Mana the buttons are not recognized when using a BIOS. Without a BIOS, works great.

PCSX rearmed needs 5500/5501/5502 for different regions respectively, this is documented in the core information, the official wiki and the OP of this thread.

and for those have trouble finding where to put these files, take a look at settings -> directory -> system

I'm not optimistic about MAME 2003 going fullspeed with Midway games (MK1/2/3/Ultimate/NBA Jam) on Vita.

Maybe MAME 2000 is a more realistic target but it'd require heavy backports.
Any hope to see MAME at fullspeed? So, if even MAME 2003 is hard, no way to have mame 2014, 2010 and so on, right? lol

TY, I missed that info, I tested the 5501 and have the same problem with Legend of Mana :(
The question is if is there a way to config pcsx_rearmed to not using the BIOS when playing Legend of Mana?

Try with one bios at a time in the "system" folder. Looking at https://github.com/libretro/pcsx_rearmed/blob/master/frontend/libretro.c#L1535
it seem that retroarch take the first bios it found. You can have 20 bios in the "system" folder, it will always take the first one it found (I did not read the source further but it seem to be this behavior).

EDIT:
Here: https://github.com/libretro/pcsx_rearmed/blob/master/frontend/libretro.c#L1569

it look for (in this order)
"scph1001", "scph5501", "scph7001", then "find_any_bios".

I think is really strange that 5 different roms, not even one works
just use fbalpha you do not need to use the neogeo version and make sure you have ALL the required files to run the game (should be 9 files in the zip folder) and the neogeo bios file in the same folder as the game
