Damn, isn't Snes emulation already perfect? I've been using Zsnes since the late 90s and never had any issues.
Unless some games have problem with ZSNES and will OK on SNES and Higan (former BSnes). Anyway, someone make ZSNES version 1.53 right now, but show change log only... https://board.zsnes.com/phpBB3/viewtopic.php?f=2&t=139390 ... no files yet since 2015...
snes is generally perfect yes but theres probably some edge cases that dont work quite right. (like carts with additional hardware in, for example). Plus updates may be necessary for compatibility with new pc hardware or windows versions.
