Sonic the Hedgehog rom hacks

I am interested in Sonic the Hedgehog (1) romhacks, from the worst ones to the best ones.

this list here on sonicretro has already a lot, but I better check with the community here to see if there's another list around, some source i could look at, or just some hack you know that's not on that list (I'm sure that's the case).

You're likely never going to find a comprehensive list. The main places I'd dig through are here and here. Also, don't forget about the Sonic Hacking Contest, which has numerous entries each year. You also may find some stuff at romhacking.net that isn't covered elsewhere.

this one is handpicked by me:

Sonic mega mix on the mega CD is a fairly awesome hack. Shame there does not seem to be very much megacd hombrew flying around, considering the ease of burning a cd
