Unfortunately, this happens to two of my three R4s.
The games will just freeze right in the middle of playing. I use untrimmed roms and it happens on any/all of them.
It is really annoying when playing Animal Crossing because then you have to put up with that Resetti bastage.
I haven't played my Switch n a month or so, just been playing Xbox, and just picked to play lil and Damn that A and B, X and Y being reversed always gets me.
I agree Tears is great. I even played thru it completely twice. I've been hooked on playing thru Fallout 4 again though, after they released the next gen version for Series S/X. Is pretty cool update.
