I'd like to /r/ if anyone knows of dead gachas or mobile games that have been made playable offline. Preferably not live-but-modded APKs. The closer to boot and play would be fine even if it's on mobile (but doesn't require root access).
An example is pick related which is a HTML5 port of a merge game, but is completely playable and completable on Flashpoint. There's no way of searching things in the description and I've tried all the usual ways of checking.
Old/dead Nutaku/DMM games would also be of curious, but that would be for me, not my mother.
