higan v093r09 released
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!

higan v093r09 (Windows binary + source)
