>>44281189I made a post on this a while ago so I'll change it a bit
Only thing that currently exists is Supernova Sun/Penumbra Moon (and Prismatic Moon/Photonic Sun) which is a difficulty catch-em-all set of hacks with various builds depending on how much you want altered. There is also Star, a joke hack for S/M
If you want a decentlist of fangames with Gen 1-7 Pokemon:
Coral
Kanlara Ultimate
Nameless
Mega Power
Resolute
Sky Twilight
Emerald Enhanced
Omega Red
(fangames, not romhacks, start here, if you're curious)
Reborn
Rejuvenation
Desolation
Empyrean
Camry Legend
Sunday
Floral Tempus
Be aware that with some of these the quality is pretty....nebulous, just be careful. Best one here is probably Coral (but it's not finished). There are also more, but I don't want to fish up absolutely everything
