Okay, so given that I couldn't get this working on the Harmony cart with two completely different 7800 models...I just acquired a 2600jr. Can't get it working on that, either...so I'm sure there's an issue somewhere with the Harmony cart.
I'm using the latest non-beta Harmony firmware, and transfering via OSX Lion...anything I should do different, or should I break down and use Winblows?
Download the latest Harmony Tool 1.3 from here: http://sourceforge.n...monycart/files/
Take out the card, and connect the Harmony to the computer with USB.
Run the HarmonyCart.app If the bottom does not report connected with a green circle, use a different USB cable.
Step 1. Select the eeloader by clicking the "... button" and double click the mounted device image called HarmonyCart, and then the arm folder which contains NTSC, PAL50 and PAL60.
........... The click the large Download EEPROM button. Unplug everything.
Step 2. Mount your memory card on the computer. Select the hbios_xxx file version from the asm folder as above. Select where your memory card is mounted. Click the Copy HBIOS button. Properly eject the memory card.
