Anyone got any info on what exactly needs to be replaced? I got a Japan V100 Board and I'm looking to make it the version that is played.
 
Code: 
ROM_START( svg )
    ROM_REGION( 0x600000, "maincpu", 0 ) /* 68000 Code */
    PGM_68K_BIOS
    ROM_LOAD16_WORD_SWAP( "svg_v200_u30.u30",      0x100000, 0x080000, CRC(34c18f3f) SHA1(42d1edd0dcfaa5e44861c6a1d4cb24f51ba23de8) ) // V200 09/12/05 16:42:51

    ROM_REGION( 0x4000, "prot", 0 ) /* ARM protection ASIC - internal rom */
    ROM_LOAD( "svg_igs027a_execute_only_area", 0x0000, 0x00188, NO_DUMP )
    ROM_LOAD( "svg_igs027a_v200_china.bin", 0x0188, 0x3e78, CRC(72b73169) SHA1(ffc0caea855ab4b01beb3aebd0bf17187c66c22c) )

    ROM_REGION32_LE( 0x800000, "user1", 0 ) /* Protection Data (encrypted external ARM data) */
    /* eproms with no labels stickers */
    ROM_LOAD( "epr.u26", 0x000000, 0x400000, CRC(46826ec8) SHA1(ad1daf6f615fb8d748ce7f98f19dd3bf22f79fba) ) // 10/11/05 10:07:20 V201
    ROM_LOAD( "epr.u36", 0x400000, 0x400000, CRC(fa5f3901) SHA1(8ab7c6763df4f752b50ed2197063f58046b32ddb) )

I think you can swap between pcb, hk, and tw by replacing the 'user1' region roms, but the v200_china version runs on a different ASIC so there's no swapping to it. Possibly there's someone out there who can take what's in mame, decrypt v200 and re-encrypt it to run on the v100 asic, but that person is not me.
 
I can probably help.. But i'm so busy now... Can it wait till after christmass?? I have a few single PCB versions here. So i should be able to test. Can you take a few pics of your board? Especially the sticker on the ASIC chip!

I'll send you pics via PM Tonight and I don't mind waiting for whatever. Everyone's busy as all get out!
 
Any progress on this? I also have a s.v.g. v100 japan pcb and being able to update to v200 would be pretty cool.
