I'm sure you know but this is a bt backwards. GD-ROMs are the native format for games because of the higher density. The Dreamcast can also play music CDs, but CD really comes into play for playing game "backups". The original content was read from the GD-ROM disks, unnecessary bits were removed, some stuff would be compressed, etc to get down to the around 800K that you could stuff onto a regular CD. I just picked up a Dreamcast before Christmas as part of a retro console spree and the modding scene is very active around it. There is the GD-emu that can replace the GD-ROM drive and store your library of games on a memory card, replacement power supplies, SDCard attachments for the console's serial port, dual-bios mods (that Dreamshell can reprogram in place!), replacement cases, and the list goes on. There is an active homebrew scene as well with some high quality games still being released. I myself want to get away from the GD-ROM for playing games as that will eventually become problematic. The GD-emu swaps out the GD-Rom but I want to keep it in the unit just because. So over the last couple days I've ordered up the parts that will add compact flash capability to the console by piggybacking on to the Dreamcast's IDE bus interface to the GD-ROM (compact flash is basically an IDE interface). But compact flash storage cards are expensive, so I'm also getting a compact flash to SD-Card adapter. This isn't new ground so far, but I think I can do this as a stealth mod and do it all within the GD-ROM enclosure.
