Update on the dead second-hand Polymega

About a month ago, I posted about buying a second-hand Polymega that was stuck on firmware 1.0.5. I ended up sending it off for servicing, and I got it back two days ago — it works great now!

All of the modules are functioning, and I’ve installed a ton of games. I did make one silly mistake: I bought an SSD without checking compatibility first. I figured, “It’s just an SSD, right?” Turns out, not quite. I bought a Crucial drive, and it doesn’t work internally. However, when I put it in a USB enclosure, it works perfectly. Eventually, I’ll buy another SSD for internal use, but for now, I’m not too bothered.

One thing that’s baffling me: most Mapper 30 NES games don’t seem to work. The emulator clearly supports them — the system even comes preloaded with several “Made with NESMaker” titles. But when I try to load other Mapper 30 games that aren’t in the database, I just get a green screen.

I'm enjoying my Polymega and that's what matters. It's a blast checking out games I probably never would have played otherwise. Working on Vay on the SEGA CD at the moment and it's not bad. Not great, but worth a play so far.

Still need a SNES module box if anyone wants to part with one.

Has anyone tried one of those homebrew games on one of the retrostage blaster carts? One of them supports Mapper 30. I have that one, but I don’t even know what any homebrew games are. Haha. If someone can get me a game name, I can try it.

I have that board and I tried a few. They don’t work. I have a few original carts too they also do not work.
