Cube64 / Wii64 v1.4.1 are released. Wii64 & Cube64 are Mupen64 for the Gamecube/Wii. Port of the popular multi-OS N64 emulator, Mupen64, to the Nintendo Gamecube and Wii through the libOGC library. The emulator currently uses dynamic recompilation of the N64 machine code to PowerPC (the Gamecube/Wii's ISA) and full hardware accelerated graphics to achieve (near) full-speed emulation in most instances.

Cube64 / Wii64 Changelog:
Wiiflow support
240p support (enable it from video settings, if a game goes interlaced it's supposed to throw you out of 240p mode)
Switch to uncompressed save states to avoid low memory zlib failures (previously made save states will be incompatible)
Minor dynarec optimisations
Fix stale save state info when switching from main to basic menu view
Mario Kart 64 in-game video billboard support under glN64 on Wii only (it's a hack, specifically enabled for this game)
