Yoru ga Kuru! -Square of the Moon- Remastered (English version)
https://www.mediafire.com/file/4nx3z3hnrh9kgus
https://vndb.org/v499

This is the uncensored DRM free version.
Technically not old since this came out last month but, outside of some shitty upscaling, it's a faithful remaster of a VN from 2001.
