When you open the WinZip window, you should see a row named CRC... If not, goto Configuration and check the CRC box there. Now you should see the CRCs of the files inside the ZIP. Now, open up your SSV DAT with Notepad and maybe you'll see something like this: (This may not be entirely accurate) %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% System: NEO RomName: samsho5 Game: Samurai Shodown 5 (Epic Center Romset) [Program] ssv_p1.rom,0,800000,8A86C728,0 [Text] ssv_s1.rom,0,20000,33227D62,0 [Z80] ssv_m1.rom,0,20000,18114FB1,0 [samples] ssv_v1.rom,0,400000,6849136C,0 ssv_v2.rom,400000,400000,222E1774,0 ssv_v3.rom,800000,400000,CD9E7ADC,0 ssv_v4.rom,C00000,400000,8B305CAC,0 [Graphics] ssv_c1.rom,0,800000,4E7BDEA1,0 ssv_c2.rom,1,800000,7B444985,0 ssv_c3.rom,1000000,800000,8C709A9B,0 ssv_c4.rom,1000001,800000,CFD53F5C,0 ssv_c5.rom,2000000,800000,C026D318,0 ssv_c6.rom,2000001,800000,B3D9D204,0 ssv_c7.rom,3000000,800000,FE03A025,0 ssv_c8.rom,3000001,800000,89DB2D34,0 [system] CartridgeID: 270 GfxCrypt: 0 GfxKey: 0 ButLayout: 9 Fix: 0 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% The 8 or so numbers before the last ',0' are the CRCs of each file recognized by the DAT. They have to match the roms' CRCs. Paste the contents of your SSV DAT if you're confused... There should be a folder in Kawaks that contain the DATs for different games...
