I have the emulator set up through the LTO software and it works. Also, I have the Ultimate PC interface. I never upgraded the firmware on my device, however, I have two flashback controllers connected to the interface using the Flashback to INTY 2 adapter cables. However, JZINTV does not recognize the controllers. On the interface the left switch is up and the right switch is down. I have 2 hackfiles to try from the intellivision.us website, however, none of them work with my current configuration. It worked before using INTY 2 controllers. Any help would be greatly appreciated. Thank you very much. I appreciate it.
