The expansion port is almost certainly not going to work. The Dreamcast G2 bus that the expansion port is attached to is specifically designed not to be able to read or write to the bus the GD-ROM is on, nor does it have DMA access to the memory mapped to the game execution.

That's what internal mods are for, baby. A chip here, a wire there, and boom; you got yourself connections. They could even make another tiny board if they had to that accomplishes what a chip cant.

Well, that's lousy to hear, but appreciate the info nonetheless. I wasn't aware of that. At this point, my primary hope is a device that has menu support, and not attached to the two crackpots who currently make them.

We're starting development again on DCIO. It will be a very high quality and much cheaper product that is easily available :)

Good to hear! I would also consider offering 3D-printed options to secure/house the board in the DC, and one that replaces the drive space under the lid.
