[SOLVED]How to use unibios in Groovymame ?

[fred92]

]Hello all from France !

I wonder how to use unibios in Groovymame launched by a frontend (i mean perhaps in command lines) ?

i tried to use the "tab" button in groovymame while a game is playing, gone to bios options, i saw unibios1 then select it then reset
and first reboot of the machine, the unibios screen is stuck/freezed, any buttons doesn't work...i tried all keys of the keyboard without success

Any help welcome.
Thanks.
Fred.


SOLVED:

in mame.ini i just wrote in "bios" line : unibios40
(located in # CORE MISC OPTIONS)

As soon as a game is launched, i pressed A+B+C keys and then unibios appears, we can select country and mod (mvs/aes)
in game, enabeling blood in metalslug : press B+C+D+START
go to setting up the soft dip, slot1 then blood ON.
then
