higan (formerly known as bsnes) is a Super Game Boy, BS-X Satellaview, Sufami Turbo, Famicom, Super Famicom, Game Boy, Game Boy Color, Game Boy Advance and Nintendo DS emulator, that began development on 2004-10-14. It focuses on accuracy and clean code above all else. It never uses speed or compatibilty hacks. As a result, the minimum system requirements are greater than with other emulators.
Here's release info:
I'm posting a beta release of higan, in the hopes of getting some feedback on the new library system (pictured below; more info on the forums), and reports of any potential new regressions before an official release.
Also, as of v093r08, the Game Boy and Game Boy Color PPU are now cycle-based, allowing raster effects such as those used in Prehistorik Man. This is in addition to several major improvements to the Game Boy emulation code.
If you're willing to test this, and provide feedback on the forum, it'd be appreciated. Thanks!
