Setting up an emulator for the PC-8801mkIISR, a unique Japanese computer, can be a challenge. This guide simplifies the process using the standard M88 emulator.

1. Download the Emulator

  • Go to the M88 Website.
  • Click download on the right menu and select the red M88 2.21a link.
  • Download M88_221a.lzh. If your browser flags it as unsafe, please proceed anyway; the file is safe.
  • Extract the contents into a new folder.
    • M88

2. Setup Compatible ROMs

  • Visit the ROM Download Page.
  • Find and click pbios00.lzh (usually the second item from the bottom).
  • Extract the file and copy the contents into your M88 folder.
    • pbios

3. Generate Character Fonts

Correct font generation usually requires a Japanese environment. For overseas users, follow these steps to generate a dummy font:

  • Download gft_1_0_0.zip from this page.
  • Extract it into your M88 folder.
  • Open the Command Prompt, navigate to the M88 folder, and run:
Gen88Font.exe --m88 --font Arial

This will generate KANJI1.ROM and KANJI2.ROM, completing the required files.

Generate dummy font data

4. Running the Emulator

  • Double-click M88.exe to start.
  • Once the window appears, drag and drop your XeGrader files into the emulator to launch them.
    • XeGrader has started
