byuu says: A new release for the new year. Changelog: fixed auto joypad polling edge case; fixes Ys 5 controls fixed Justifier polling code; Lethal Enforcers should be fully responsive once again rewrote SNES S-SMP processor core (~20% code reduction) fixed Game Boy 8x16 sprite mode; fixed some sprites in Zelda: Link's Awakening treat Game Boy HuC1 RAM enable flag as writable flag instead; fixes Pokemon Card GB created far faster XML parser; bsnes can now load XML files once again updated to mightymo's most recent cheat code database internal color calculations now performed at 30-bits per pixel gamma slider now acts as fine-tuned gamma ramp option Linux OpenGL driver will output at 30bpp on capable displays Linux port defaults to GTK+ now instead of Qt (both are still available)
