# Touhou Reiiden: a C# port built around original PC-98 game data

> Touhou Reiiden is a C# and .NET 8 port of the 1997 PC-98 game that loads assets from the user's own disk image or game folder. It rebuilds stages, bosses, menus, scoring, and audio, using ReC98 as a behavioral and file-format reference and measurements of the original for selected boss sequences.
