I looked through the Harmony manual, and didn't see anything on this topic. Is there a way to have a SD card with a single ROM file on it, like a "autorun.bin", that would be loaded automatically and started when the 2600 was turned on? I want to use my Harmony cart for an art exhibit at Maker Faire NYC next weekend, but I don't want to have a joystick hooked up to the 2600 or anyone to have to interact with the console once it's turned on.
[Edit: looks like I can use programming mode to just load a single game onto the board without the standard multicart firmware. This should work for my needs, but I like the idea of autorunning from SD too, so I'm leaving this post around.)
The best way is to use the single program mode as you discovered.
However, the Harmony cart does also have an autorun mode. Just name the game image AUTORUN, and place it in the top (root) directory on the SD card.
