sonic and black night - NTSC version wont play

[dell_xps]

finally got it working, downloaded a patched Gecko 1.7 that has the 002 fix on, went into Gecko set config to Foirce PAL 50 MHz and worked, initially set the option Force NTSC but got a b&W only, realised I had Patched the ISO file to PAL so tried the other Force option and jobs a good one

now after all this, the PAL version has been released - will download that as well

Glad you got it working in the end.
