I know Sonic CD and Sonic & Knuckles Collection can't be uploaded to Abandonia yet (not until 2011 or 2012). But when that day passes, can I please be the one to upload it to the site?
I own the official CDs.
I applied a No-CD Crack to Sonic & Knuckles and included a patch to make the game run at normal speed in windowed mode on modern systems.
I dumped a full ISO of Sonic CD for uploading to the site. I included the patch to make the game run on XP, Vista, and 7, plus (as a bonus), I made an alternate version with all the American music from the game replaced with the original Japanese music.
Take some time to think about it, but I really want to do this.
