Hi, I have a modified Dreamcast on it's way. It has an overclock Switch, a VGA port, and dual BIOS Switch to go between loading from discs and Dreamshell. All the features I'd want except for hard drive loading, but there apparently isn't room to add an IDE mod to the mix. At least not while retaining GD-ROM functionality.
I got to thinking though: Since the GD-ROM basically just plugs into a socket,what if I purchased an extra GD-ROM and a USB-GDROM mod and a 3D printed cover to be put together as a complete assembly with the USB socket on the inside? If I did that, could I use the GD-ROM when I want to rip my own games or play from disc and then Switch the assembly out for the modified assembly and then be able to Switch it back out later?
In that scenario though, how would it work? The main BIOS is configured to run disc games, with the second BIOS configured to look for files on the SD card to run Dreamshell. Would the USB-GDROM run from the main BIOS using it's own loader software? and for disc swaps, I'm guessing the menu comes up to select the second disc when I open the disc tray?
In either case, if this would work, it seems like the best of two worlds scenario - unless someone can suggest a viable alternative to having to go back and forth?
An additional concern though is that, looking at installation videos, I see some versions that use a cut out on the back and others that have it pointing inward. Is that a choice made on installation? Or how will I know which style I would get? Ideally, I'd like to be able to take the mod out at any time and go back to using discs, so I'd like to avoid the style that pokes through the back.
