Good but can’t import mods

Certain mods can’t imported because of too many files in the archive that’s what it said don’t know what to do

Some mods aren’t able to be imported.

It’s a great app but all of sudden(could be because of an update)certain mods can’t be imported the app tells me “the mod archive contains too many files”like for wilds of kanto… can you please fix this I appreciate your work.

So cool

Been using this for a few days. Dev is super responsive on Reddit and really helpful. UI is something special. Adding your games and mods is ez.

You don’t really find emulators that are this pretty, and certainly not this easy.

Someone get this man some head pats!

Great but haptics are broken.

Great emulator. Minor issue. The new haptic feedback function is broken. When the haptics are toggled off they still occur. Changing the slider has no impact in intensity either.

Tested this on Pokemon recomp mod.

Response from developer

Hey! Thanks for the review. You can turn off haptics in the in-game options menu for modded games. The app runs off two different cores, so the modded games have a lot of options only manageable in game.

Best ever

Best gaming app ever

Response from developer
