If you’re happy with EmuDeck, and how it performs/where it stores things…then by all means stick to it! There’s no need to abandon one for another. You can always just try RetroDECK, if you have a micro SD card its even handier that way as it will install there. Watch this, just so you’ve got a good idea of things!

As to uninstalling, if you’re dead-set and serious about removing it entirely, then I’m happy to help you via DM if you’d like? It can store data in so many different places, which really made me so cross. I know the spots though, happy to take you through it step-by-step if you’d like. I’m here, and on Mastodon, and Matrix if any of those places work best for you (and, if you do need help!)
