Heres a great new Snes Emulator for the Nintendo Switch:
Hi, here is something i'm working on since a while now, but as my time is very limited... There is now other alternatives but... well
Installation
copy "psnes" directory to "/switch/" directory on sdcard
copy roms to "/switch/psnes/roms/" directory on sdcard
Information
pSNES "should" work on any firmware (based on libnx and snes9x.git)
pSNES actually support save states, 2x, 3x, fit, fit 4/3 and fullscreen hardware linear scaling and a simple (but nice?) ui.
pSNES ui support titles images (png), named as the rom name with png extension instead zip, in the "previews" directory (to be created if needed).
pSNES does not actually support high resolution games...
pSNES use a database file for rom handling. You'll need a "db.xml" file located alongside the application. The current "db.xml" file comes from "Hyperspin" website, and only contains USA "good rom / no-intro" set. Your rom files must be zipped and named as per this set. You'll find in the "database" directory this file as backup/reference (Super Nintendo Entertainment System - hyperspin.xml) + a complete set from dat-o-matic (http://datomatic.no-intro.org). Rename this file to "db.xml" and (re)place it in the same directory as the executable to use this one. You can make your own database file with filtering from this great website.
