original (no including wii) QUASI88 site (only in Japanese): http://www.117.ne.jp/~show/pc8801/pc88emu.html


  • Wiimote, Classic, and Gamecube controllers
  • USB-mouse & USB-keyboard
  • snapshot (bmp or others)
  • state save & load


  • USB-keyboard (may be able to execute all solo-play games without USB-Keyboard by editing /quasi88/rc/quasi88.cfg)

How to set up

1) Copy the contens in the HBC directory to your SD/SDHC card or USB storage.

2) Copy system roms files to /quasi88/rom directory.

3) Copy game roms files to /quasi88/disk directory.

The details of the systems roms are announced the following site (but only in Japanese) http://www.117.ne.jp/~show/pc8801/quasi88/rom.html
