After being on hold for a while, IntelliXpander is moving along again. And we got to the point where we must decide about case design, so we can design the final PCB to fit that.
Unfortunately we can't make multiple versions, that would be insanely expensive. So we must decide if we should go Intv I or Intv II style.
A second question would be about cartridge format. We have both the option to keep using the Intv regular cartridge case or come up with a new cartridge format for the IntelliXpander games. Each has pros and cons. A new format means having two cartridge slots, one for legacy regular games and another for IntelliXpander games. Using the regular Intv cartridge means having a single cartridge slot, for both regular and enhanced games. Since we don't have an easily accessible mold for Intv cartridges, we will have to create one (as I don't want someone dictating me what I can and what I can't release), which means another huge investment. But having a single cartridge shell I can use on both ColecoVision SGM and IntelliXpander games would be a huge money saving and speed up things considerably. In the end it doesn't matter, to run IntelliXpander games you need the IntelliXpander, which would have the new cartridge slot anyways. It is probably more of a purist thing, I am checking if the idea deeply bothers the purist in you.
Your input would be greatly appreciated.
