Hey. I'm just wondering if popcap games like peggle and plants v zombies can be ported to the switch

Almost all PSP Minis work in RetroArch with the latest PPSSPP Patreon build btw. Might be worth a look for those "quick grab" games like angry birds and others.@minomore
The PSP version of Peggle is perfect. Resolution to 1440x816, no overclock. As for Plants vs Zombies, there are NES and Sega Genesis fanmade versions, but they are heinous. Still got to figure out how to get Bejeweled 2 running good.
Some other PSP games from mobile like Jetpack Joyride and Angry Birds {AB has that, built-in, PlayStation sticky controller issue} decent, too. Also Canabalt.
Turn Fast Memory Speedhack to off in the settings for Peggle. https://twitter.com/m4xwdev/status/1117513300521172993

I have the majority of the ones I want to play running. I'll have to do some more tinkering for Bejeweled 2, though. If you get it smooth, please let me know.
As for the Angry Birds thing I mentioned, it seems the controls weren't too optimized for their PlayStation releases. I get that same 'sticky' issue on the PS3 version.
Disable Fast Mem, Vertex, and Unsupport Func. (Each says (speedhack) next to the name) see if that works.
