RB's Notes 2: Included in subfolders are the separate patches that make up this compilation hack. If you'd rather create your own feature combination, feel free. Apply them to an unmodified ROM.

RB's Notes 3: The original ROMs are kept in the post for purposes of customizability. In my testing, The Retro Bit one worked fine even on ancient emulators like Kega Fusion, while the Genesis Mini one worked only on Blast 'Em and via Retroarch cores.
