Reverse engineer retires after one feature breaks the entire Touhou PC-98 project

Reverse engineer of PC-98 Touhou games retires

The ReC98 project, which reverse-engineers the PC-98 Touhou games, is shutting down.

Along the way, the author found point items can underflow to negative values, a bug hidden for decades by a font with no minus sign.
