What do you mean what version of KOF2003...there are only two (The original release and the fixed release)...they should both work...but I will look into it

What You Need:-
-Links removed. Read board rules.-
And finally the mame kof2003 rom, here's the crc:
271-P1.bin CRC: 92ED6EE3
271-P2.bin CRC: 5D3D8BB3
271-S1.rom CRC: C47F8AC3
271-M1d.bin CRC: 0E86AF8F
271-V1d.rom CRC: D2B8AA5E
271-V2d.rom CRC: 71956EE2
271-V3d.rom CRC: DDBBB199
271-V4d.rom CRC: 01B90C4F
271-C1d.rom CRC: E42FC226
271-C2d.rom CRC: 1B5E3B58
271-C3d.rom CRC: D334FDD9
271-C4d.rom CRC: 0D457699
271-C5d.rom CRC: 8A91AAE4
271-C6d.rom CRC: 9F8674B8
271-C7d.rom CRC: 374EA523
271-C8d.rom CRC: 75211F4D
First put the 271-p2.bin(5D3D8BB3) through the 2k3_fix, you should get 271-p2BL.bin(bf7bf5fe). Again, take that same 271-p2.rom(5D3D8BB3) and put it through the test_px.bat located in the test.zip. Take either the p2_3.bin or p2_4.bin and name it 271-p3.rom(7BC100DF). Now take the 271-s1.rom(C47F8AC3) and process it through fix#1 of the s1_fixes to correct the infinite symbol bug. The 271-S1.rom(C47F8AC3) should now be 271-S1.rom(7c7829aa).
Put all the roms together and it should look like this.
271-c1.rom CRC (E42FC226)
271-c2.rom CRC (1B5E3B58)
271-c3.rom CRC (D334FDD9)
