En regardant dans le source de mame on constate quelques variantes 2slots/4slots mais c'est tout donc faut voir de plus près.



La différence principales sont les régions à  priori:



SYSTEM_BIOS_START( neogeo )

SYSTEM_BIOS_ADD( 0, "euro", "Europe MVS (Ver. 2)" )

SYSTEM_BIOS_ADD( 1, "euro-s1", "Europe MVS (Ver. 1)" )

SYSTEM_BIOS_ADD( 2, "us", "US MVS (Ver. 2?)" )

SYSTEM_BIOS_ADD( 3, "us-e", "US MVS (Ver. 1)" )

SYSTEM_BIOS_ADD( 4, "asia", "Asia MVS (Ver. 3)" )

SYSTEM_BIOS_ADD( 5, "japan", "Japan MVS (Ver. 3)" )

SYSTEM_BIOS_ADD( 6, "japan-s2", "Japan MVS (Ver. 2)" )

SYSTEM_BIOS_ADD( 7, "japan-s1", "Japan MVS (Ver. 1)" )



SYSTEM_BIOS_ADD( 8, "uni-bios.10","Unibios MVS (Hack, Ver. 1.0)" )

SYSTEM_BIOS_ADD( 9, "uni-bios.11","Unibios MVS (Hack, Ver. 1.1)" )

SYSTEM_BIOS_ADD(10, "uni-bios.12","Unibios MVS (Hack, Ver. 1.2)" )

SYSTEM_BIOS_ADD(11, "uni-bios.13","Unibios MVS (Hack, Ver. 1.3)" )

SYSTEM_BIOS_ADD(12, "uni-bios.20","Unibios MVS (Hack, Ver. 2.0)" )

SYSTEM_BIOS_ADD(13, "uni-bios.21","Unibios MVS (Hack, Ver. 2.1)" )

SYSTEM_BIOS_ADD(14, "debug", "Debug MVS (Hack?)" )

SYSTEM_BIOS_ADD(15, "asia-aes", "Asia AES" )

SYSTEM_BIOS_END
