Touhou: 4 Open Source Clones Compared
ReC98 is a reverse-engineering project for the original PC-98 Touhou games and requires the player's own copy of the original game files to run its compiled executables, with development described as sporadic. Taisei Project is a different kind of project entirely — an independent fan-game with its own SDL2-based engine, music, and art that needs no Touhou data at all, and unlike ReC98 it sees active development.
