Beiträge von mega65 im Thema „Expansion port support for this ?“

    Tell me more about the hardware on the cart, and how it communicates via the user port.
    Are you using just the 8-bit data port, or also shift registers? Any other signals?
    What combinations of input and output on the user port?

    As I mentioned, we have planned for a while to make a user-port cartridge, that will act transparently just like the user port.

    Howdy,

    The expansion/cartridge port already works quite well, and supports $DE00, $DF00 I/O as well as the usual ROM select lines, so if the cartridge doesn't do anything too odd, it should be okay. If we were able to play with one of the cartridges here, I would be able to confirm and/or fix any problems we see. We are in the process of getting the MSSIAH cartridge support already, if that helps.
