NeoKobe PC-98 Style LoRA

A LoRA trained on the NeoKobe PC-98 game image archive, one of the largest collections of CG art from classic NEC PC-9801/9821-era Japanese games (circa 1985-1998).

Captures the aesthetic of PC-98 era game art: flat cel-shading, limited palette, soft linework, and the distinctive bishoujo game illustration style that defined Japanese PC gaming in the late 80s and 90s.
