DraStic

First of all, I really loved this emulator and I'm happy with the nice work on this project.
Basically, the problem beggin when I decided to capture the regirock,registeel and regice.
I just got the regirock and Save the game, after this I restarted......
And the blue screen appears with this text"the save file will be erased due to corruption.
I'm very sad because I spent a lot of time with this game.....

Well... That sucks.
You may want to use both in-game and quick saves. Every time you save in-game, also save a savestate as soon as it finished saving normally. You can have a way to return to your save even if one gets corrupted.
Also, enable auto saves in the Drastic settings for another layer of security
