Fur Fighters not working, a patch problem ?

[tomawashi]

Hi,
I tried to burn "Fur Fighters" (the Kalisto release, not selfboot) after having patched it with PAL 2 NTSC Patcher. I tried to run it on my DC, of course with the boot cd, and the loading stops at 96%... I then made a selfbooting nero image using Bin2Boot and cdi2nrg, and it freezes at the SEGA screen.

Unfortunately, I don't have the original image anymore, so I can't burn it without patching it to make sure it is because of the patch.

What can I do ? Is there a way to "reverse" the patch to come back to my original image ?
Thanks.
