SDISO Compatibility List

[SWAT]

So you not need repack gdi image. You need to getting only one track03.bin (if game not have CDDA tracks) and convert it to ISO by my ISO Make pack v2 just clicked to bin2iso.bat. After this try run, if game works, you can try compress image by compress_iso.bat and try it again.
If game have CDDA tracks, need to repack gdi by repack_gdi.bat or make iso with padding as it could be with cdda tracks, but this more hard for you.
