How To Put 2 Homebrew Games On 1 Neo Geo Pocket Color Flash Masta Cart

Above is a video I just uploaded. In it, I detail how to go about putting two games on a single NGPC Flash Masta cartridge. I’m sure this is obvious to some people, but there are lots of people that want to see how this works before attempting it themselves. I’m the same way with lots of stuff.

In other news, I’ve been working on an adapter to use 5 SNES controllers on a Turbo Grafx 16, PC Engine, TurboDuo, etc. It’s pretty much a Multitap/Turbotap for the PC Engine, but it allows you to use ultra-cheap SNES controllers (which you may already own) instead of expensive PCE/TG16 controllers. Here’s a little picture of the current prototype. At the moment, it only works with a single controller, but adding the other 4 should work. It just takes a bit more doing/debugging.

I’m not yet sure what I want to do with this project, so if you’re interested in the SNES to PCE Turbotap, leave a comment.

    I am intrigued by this multitap… though I don’t have any multiplayer games for my TG16 yet, haha. Any recommendations?

      I think you can’t go wrong with Bomberman. Otherwise, I really haven’t had time for gaming lately.

    I would love to buy a snes multitap for my turbografx16! If you ever produce a run of these count me in for sure! Another great project, very cool.

      I’d really like to make a run of these, but they’ll be more complex to produce than the Linkmasta. It would have to either be just a bare PCB or I’d have to get a plastic case designed and fabricated. I think that’d be very expensive for a small run. I may also be able to retrofit a SNES multitap, but then each unit would need to start from a SNES multitap. That could be expensive, too.

      So, I’ll get one working fully first, then I’ll figure out how to produce some.

    Thanks for these videos. While I was able to puzzle out how to do this on my own (as well as installing the drivers), it’ll be nice for future owners of the Flash Masta. I’m still loving my cart!
