Didn't know that Atariage had a custom cart ordering option on their store. Do we have permission to do this? If so would it indeed work with a Melody board? That's one of their options aside from Legacy.

Hi! Feel free to have AtariAge built you carts of the game, as long as you don't resell them for profit (I mean, the game is freeware).
This game does require a Melody board to work on real hardware. The Melody board uses the same ARM coprocessor as the Harmony cartridge, but for a single fixed game instead of an SD card.
By-the-way, I do plan to make an expanded / full version of this game someday, and hopefully make it good enough to be worthy of a boxed physical release :)!
In the meantime, I'm glad that you're enjoying this Jam version enough to want to have an actual cartridge of the game!
