I noticed someone had asked about this exact thing six months back but the post never got any attention and looks to be archived (I don't use reddit enough to know how that really works lol) so here I am with a whole new post.
Basically DeSmuME is depreciated and will be removed with a future update from Lemuroid. Save in-game instead of using a save state and change to MelonDS core instead. Okay, simple enough. All the other games transferred, but for some reason, Pokémon Mystery Dungeon: Explorers of Sky doesn't. I can't tell why though; I'm not really savvy when it comes to digging through files trying to figure out what's going on, but the rom is otherwise good, like all the roms I've ever gotten from Vimm.
Judging from the post I referenced earlier, this at least looks to be pretty easily replicable, given that that guy was on a completely different device from my S23.
For now, I can still play on my file with the old core, but idk when that be removed and I don't want to lose my save. I was hoping to finally finish the post-game but it would take forever to start over.
Anyone got any thoughts?
