Quick overview of known system ROM versions, may not be completely accurate. Various third-party system ROMs (e.g. Universe BIOS, Neopen BIOS, smkdan's Diagnostics BIOS) are missing from this list.

Filename	Short Name	Region	Reported Version	Description
sp1.jipan.1024	japan-s1	Japan		Japan MVS v1
sp1-1v1_3db8c.bin	japan-hotel	Japan	6, NEO-GEO GIT Ver 1.3	Japanese Hotel v1.3 (Copyright 1993)
sp-j2.sp1	japan-s2	Japan	5	Japan MVS v2
vs-bios.rom	japan	Japan	(JAPAN) Ver. 6.00	Japan MVS v3 (Copyright 1995)
japan-j3.bin	japan-j3	Japan	(JAPAN/J3) Ver. 6	Japan MVS J3 (Copyright 1995)

sp-45.sp1	mv1c	Asia	(ASIA /S3) Ver. 6	NEO-MVH MV1C (Copyright 1995)
sp-e.sp1	us-e	USA	5	USA MVS v1
sp-u2.sp1	us	USA	5	USA MVS v2?
sp-s.sp1	euro-s1	Europe		Europe MVS v1
sp-s2.sp1	euro	Europe	5	Europe MVS v2

todo: USA system ROM exists, even if most people swapped out the chip. Has it been dumped? Same question for Korean and PAL home consoles.

Filename	Short Name	Region	Description
neo-po.bin	japan	Japan	Japan AES
neo-epo.bin	asia	Asia	Asia AES
neodebug.bin	devel	Japan	Debug/Development

Regions are handled via a set of jumpers. Does the Brazilian/Portuguese language system have a different system ROM?
