Developer eke-eke has recently announced the release of a new build of the Hu-Go! GX homebrew application for the Nintendo Wii console. This app, in case you're a first-time reader, is actually an emulator that will enable you to run games originally meant for the PC Engines and the TurboGrafx-16.

Among other updates, this new build will include support for up to four players, and support for Wiimote, Nunchuk, and Classic controllers. As for the rest of the changelog (quoting the readme):

* [PCE]
o sourcecode cleanup
o fixed multiplayer support (max. 4 players)
o added preliminary Super CD-ROM support: Data only (.ISO & .BIN image files), no CDDA track support
* [NGC/WII]
o fixed progressive mode support, now automatically detected
* [Wii only]
o added automatic TV mode detection (from SYSCONF), no more PAL60 version needed
o added option to return to Wii System Menu
o fixed "TP reload" option: now compatible with HB channel
o removed SD-Gekko support (Wii slot becomes default slot)
o added Wii SD slot support for WRAM files
o added Wiimote, Nunchuk & Classic controllers support through libwiiuse (see User Manual for default keys)
o sourcecode
* Known Bugs:
o WRAM Load & Save options are inverted
o 480p is not enabled by default when detected, you have to switch PROGRESSIV rendering mode in options to have it enabled
o some games have missing sound and graphic glitches due to some emulation inaccuracy
* ISO/BIN Support:
o a ROM image of the System Card (better use 3.0) must be renamed as syscard.pce and placed into /hugo directory
o CD Audio & ADCPM playback is currently NOT supported

Full details on installing and running this emulator on your Wii are available in the file bundle's readme. Enjoy the download, and be sure to keep on the lookout in case any new builds are announced in the near future.
