So I won a PSP lookalike in a contest recently, and it's your typical portable GBA/NES emulator. Most of the games on it are simply ROMs of licensed GBA games, but I saw a few original-looking games hidden among them. I later found that most of these were ports of JungleTac games. Most of them are available here. However, there were a few that I couldn't trace:

"On no Off" (actually Lights Out): https://imgur.com/a/6mcqp

Mr. Onion (port of the JungleTac game): https://imgur.com/a/GVnIK

Play Plane/Lightning Plan: https://imgur.com/a/ubvoW

The two in particular which I couldn't find anything about are On no Off and Hanoic Tower. I suppose these were made especially for these GBA emulator manufacturers or something.
