DraStic

Just disable the Start and Select buttons and that shouldn't be a problem.

Try blowing harder then. You are clearly getting somewhere with this.

If it works like other DS games, then you should be able to just blow on the microphone to blow em off.
(BTW, try posting in English next time, so we can understand your problem)

Are you running Android 11?

Can you be more specific about your problem?

Maybe you are using cheats designed for a US version. Did you try them on a US copy?

Savestates <> Saves

Have you tried deleting the save files that are already present? They should be on the backup folder of your Drastic folder.

Tried disabling Preloading unzipped games to RAM?

Tried reinstalling the app? That is likely to fix any config-related issues.
