Uni-Bios in MAME
Posted 07 January 2004 - 12:29 PM
I've been trying to boot neogeo games in MAME using the unibios. The only way I've found is renaming it to another bios name (in my case vs-bios.rom)... I was wondering: since MAME runs "hacked" games by default, I thought maybe it could run a hacked bios also without any such tricks.
Not that using this trick is really a problem, but I always get the wrong crc message, which is a little boring in the long run, and I'd prefer to leave the neogeo.zip as it is for other emulators.
Should I add a driver for it or is there a simpler way?

As a repent , for those interested here is what I added:
in driver/neogeo.c, under SYSTEM_BIOS_START( neogeo )
SYSTEM_BIOS_ADD( 7, "uni-bios.12","Unibios MVS (Hack, Ver. 1.2)" )and under #define NEOGEO_BIOS \
ROM_LOAD16_WORD_SWAP_BIOS( 7, "uni-bios.12", 0x00000, 0x020000, CRC(4fa698e9) ) /* Universe Bios v1.2 (hack) */and in ui/properties.c in InitializeBIOSUI(HWND hwnd) (near the end, after the other ComboBox_AddString)
ComboBox_AddString(hCtrl,"Unibios MVS (Hack, Ver. 1.2)");Next time I'll try harder to find the answer before asking the question

@james: that's what I thought I had read in another thread, but how do you enable it? In Default Game Options -> Misc. I only see the 7 normal bioses (0-6)?
