byuu says: Changelog (since v076): - video filters and shaders now populate inside main menu; no longer have to select them as files - fixed 2xSaI, Super 2xSaI and Super Eagle on 32-bit platforms; still buggy on 64-bit Windows - fixed linear mirroring issues (fixes Mega Man X dash bug) - fixed RAM memory mapping bug in Sufami Turbo games - home folder is now %APPDATA%/bsnes or ~/.config/bsnes - added paths.cfg file, which will allow you to specify custom paths for any file types - save states and cheat files for multi-slot games are based on slot names instead of BIOS names - fixed compilation warning on OS X with nall::decimal - fixed calculation bug in nall::fp - Makefile now has options variable, example: make options=debugger - configuration files and cheat database can now reside in the same folder as the binary itself - updated to 2011-03-11 release of mightymo's cheat database
