Pablo, 09:19 CET, 2010/02/05: MERLiX: That's old news :P
MERLiX, 00:19 CET, 2010/02/05: New SONIC Game :)
Shadow, 11:22 CET, 2010/02/03: Hello pals ;)
thals1992, 21:37 CET, 2010/02/02: Ive used the same bios since i downloaded the stuff in 2006 and the only problem was that the boot screen audio didnt stop when I went into the cd player menu.
thals1992, 21:37 CET, 2010/02/02: I inserted the SonicCD for SegaCD in the drive running KEGA. Ive used the same settings on three different computers. The problem one seems to only be on windows 7.
thals1992, 21:27 CET, 2010/02/02: BTW I did have the PC version before I traded in for the real deal I fonld the PC patch and it worked on XP even vista. Patch was at http://www.sonic-cult.org/download.php?site=1&filename=SonicCDfix.exe
King, 18:20 CET, 2010/02/02: Oh, if it's the PC version you're probably screwed. :P
SmartOne, 06:27 CET, 2010/02/02: Unless it's the PC version.
King, 05:39 CET, 2010/02/02: Make sure you have the right BIOS and a BIN/CUE rip of the game. It works perfectly for me on Windows 7 x64 so it has nothing to do with the version of Windows. :)
thals1992, 03:27 CET, 2010/02/02: Aww man I cant run My SonicCD Game from my Windows7 x64 PC. I almost want to downgrade back to Windows XP.
