General Discussion / Re: SEGA SMS/GG Firmware (FW v0.24)

This is great! I updated to this firmware and built a "Mark Master Converter". With those I'm able to dump+emulate many SG-1000 and Mark III games — both cartridges and My Cards — by stacking the Mark Master Converter atop the PlugIn Master. However, my adapter may have some sort of bug - there are a few SG-1000 cartridges I have not been able to use with the Retrode2, and they load as entirely 0xFF bytes:

  • Congo Bongo
  • Flicky
  • Girl's Garden
  • Star Jacker

Strangely, those very same games work fine (other than missing SG-1000 color palette set-up and needing a quick cartridge-swap to defeat the BIOS checks) in a Game Gear by stacking the same Mark Master Converter on top of the Beeshu Gear Master. Also, more than a dozen other games — including SG-1000 and Mark III cartridges and also My Cards — work fine with the Mark Master Converter atop the PlugIn Master in the Retrode2.

Before I go too much further into debugging these, has anyone else been able to successfully use any of these SG-1000 titles via the Retrode2?

edit: got one of skaman's Mark III Plug-Ins (thank you!) and see the same behavior with that as with the two-adapter stack - however, it's a beautiful Plug-In, works fine with actual Mark III cartridges, and I highly recommend it :)
