byuu says:
- bsnes: added video filters from bsnes v082
- bsnes: added ZSNES snow effect option when games paused or unloaded
(no, I'm not joking)
- bsnes: added 7-zip support (LZMA 19.00 SDK)
[Recent higan WIPs have also mentioned bsnes changes, although the higan code
no longer includes the bsnes code. These changes include:
- higan, bsnes: added EXLOROM, EXLOROM-RAM, EXHIROM mappings
- higan, bsnes: focus the viewport after leaving fullscreen exclusive
mode
- bsnes: re-added mightymo's cheat code database
- bsnes: improved make install rules for the game and cheat code
databases
- bsnes: delayed construction of hiro::Window objects to properly show
bsnes window icons
