Ratings and reviews

This app is awesome, does a great job. I am very annoyed the load state is both A. Defaulted to a quick action button and B. Doesn't prompt for confirmation with a warning. Didn't realize what that button was until I lost 2 days worth of progress because I tried to swipe to see notifications.

This has been a great app which I've been using for many years. However, I tried to play a game this evening on my Pixel 6a and no games are recognised (despite me authorizing access and the files being present). UPDATE: I found the answer in a review for the John GBA app - the game files must now be put in a subfolder called game. Working again! Still a fantastic app.

In-game saves have never worked properly and now it can't read my game files even though I've directed it to the correct folder - which contains the correct format files - multiple times now. I used to love this emulator and now it's just not working like it used to
