A Game Boy Advance / Game Boy emulator for the Wii based on VBA-M and Visual Boy Advance v1.7.2.

Features

  • Wiimote, Nunchuk, Classic, and Gamecube controller support
  • Custom controller configurations
  • SD, USB, DVD, SMB, GC Memory Card, and Zip support
  • Turbo speed feature
  • SRAM & State saving
  • MEM2 ROM Storage for fast access
  • Auto frame skip for those core heavy games
  • GBA compatiblity based on VBA-M r750, GB compatibility based on VBA 1.7.2

Notes from the Developer

  • Speed could still use some improvement. If anyone can make the code more efficient, or is able to activate the PPC assembly code inside, or can make it faster in any way, let me know.
  • Sound tends to rebuffer as a result of frameskipping, so in-game music may suffer as a result, sounding like a CD-skipping. This does not occur with Gameboy Color games or original Gameboy games, which do not use the frameskip function.
  • Everything's been ported from VBA-M, except Blaarg's new sound core and the GB core. These I haven't gotten working (they just crash). If anyone can help debug the reason(s) why, please contact me - I would appreciate the help! The new sound core is supposed to have much better performance (speed), and should make things sound better since it has interpolation. The VBA-M GB core also has a LOT of improvements.
  • Frameskipping is a bit choppy. It reacts slowly to slowdowns, and then overcompensates and skips too many frames. If anyone can improve the frameskip formula, let me know.
  • There's minor screen/sound corruption when switching to a new ROM or from a GB rom to a GBA rom. If anyone wants to fix this, let me know!
  • Some games will report that your save is invalid, but then load it up fine anyway. If anyone can fix this, let me know.

Installation

  • If you are using the Homebrew Channel just copy the apps directory from the archive to the root of your SD card. If you are using another loader use the executables/vbagx_wii.dol.
  • ROMs & saves files should be stored in vbagx/roms and vbagx/saves on the root of your SD card or USB flash drive. You can copy the vbagx directory from the archive to your support drive. Your ROMs must be in ".gba" format.
  • Launch the emulator using your Loader.
