I'm wondering: 1. Are there any hacks of Sonic 1 that adds a spindash and nothing else? 2. Are there any hacks of Sonic 1 that adds SRAM saving and nothing else? 3. Are there any hacks of Sonic 2 that adds SRAM saving and nothing else? Yes, I'm aware that Sonic Classic Heroes effectively accomplishes both of this but the S3&K-style sprites and other added stuff makes it no longer feel like Sonic 1 and Sonic 2 to me, and I just want to play vanilla Sonic 1 and vanilla Sonic 2. If there aren't any 'simple' hacks like this, then I guess I'll just do it myself, but unfortunately I'm quite busy with another project at the moment.
