Note
Rumors (provided by noemi (nyoemii) & miracle (SimplyAe)): Ainu builds are reportedly still circulating, with some claiming to hold the original source and allegedly using AI to produce new versions. This is unconfirmed rumor and speculation only: the source appears lost to time and/or kept private by Cherry, and Chewy/Pythr has deleted his GitHub account.

From hinamizawa: We also picked up a very unique Ainu build of our own for the archive, with noticeably different design work compared to the copy above. It's different enough that it could mean a third person out there holds some version of Cherry's original source, though that's unconfirmed and purely a rumor for now. Call it Ainu Enhanced: currently kept internal while we verify and test it, so there's no download yet.
