I bought one of the Timeharvest USB superguns awhile back. I haven't seen anyone post a compatibility list, so I figured I'd put together what I've tested. If anyone has any information to contribute, I'm glad to add it to my post. For context, I've tested on the USB Cbox 3.0; I don't know if...
I've bought from sheep_nova twice now and had a great experience both times. First time I got a PGM with several games, second time I bought a single PGM cart. Both times, everything was shipped promptly and perfectly-packaged, and works great.
