Dekopon - (Mostly) Fullspeed 3DS Emulation on Nintendo Switch

Does anybody remember the setting to change to fix the issue with the top screen flickering with the lower screen visuals? Particularly bad in A Link Between Worlds. I had this same issue with Azahar on Switchroot Linux and do not remember how I ended up fixing it...

The performance preset is the recommended settings. You can try some of the hacks for more performance, but they very well may break things.

Did anyone get USUM to boot? Whenever I try to run it, it just flashes a dual screen and nothing else happens.

Edit: Just made the account to comment in this, amazing work on the emulator!

A new release has been made that hopefully fixes the long pauses that occurs after playing games for longer periods of time: https://github.com/PalindromicBreadLoaf/dekopon/releases/tag/v2.2.2

@FashionNugget specifically this should fix the issue you were having previously. Hopefully. I can't guarantee anything 100%.

USUM should be working just fine. It may take a little bit to start up, but not a crazy long time. Does it exit back to the menu after the flash or does it just sit there?
