I've been playing around with the DPC+ kernel for weeks now and would like to use it for my next project. I usually start my projects with a basic game engine and then see if I can come up with a good game concept around it, which is what this is. I have a hard drive full of abadoned projects just like this one that just didn't work out. This demo works perfectly in Stella but loads with a blank black screen on a Harmony cart on real hardware, and I was hoping someone more knowledgable than me might be able to figure out why.
This game is a platformer and there are 15 screens that you can freely roam left to right. My idea was to have random treasures, enemies and ladders on each screen, and all the rooms would connect in a large maze-like world. I don't have any other ideas past that, this is just a proof of concept at this point and the sprites are just placeholders. The ladders probably won't work correctly on any of the screens beyond the initial screen, I haven't gotten that far yet. I've really only worked on the first screen. I'd just like help figuring out why it doesn't seem to work on the Harmony.
EDIT: The latest version is titled "jadv" (August 2013) and it will run on the Harmony.
