history

Project history and usage

QUASI88 is S. Fukunaga's PC-8801 emulator for SDL2-capable Windows and Unix-like systems.

Project history

The official site says QUASI88 was created with reference to fMSX source code, uses sound-driver code from MAME and xmame, and includes the fmgen FM sound generator. The site carries copyright years 1998-2026 and lists version 0.7.4 as released on 2026-05-01.

Adoption history

QUASI88 has long been packaged by Unix-like package managers because it gives retro-computing users a small, SDL-based PC-8801 emulator with command-line startup and documented ROM and disk-image handling.

How it is used

Users run quasi88 after providing PC-8801 ROM image files. The official how-to documents QUASI88_ROM_DIR and QUASI88_DISK_DIR for locating ROM and disk images, command-line startup with disk images, and menu-mode configuration through function keys.

Why package nerds care

QUASI88 is the kind of emulator package that exposes old-platform preservation details directly to packagers: external BIOS ROM requirements, D88 disk image support, SDL2 linkage, and careful separation between distributable emulator code and user-supplied copyrighted ROM images.

Timeline
