Sure thing, sorry about that. I can't find a delete option, but I can edit it and erase all content. I Really only uploaded it so I could link it in the comments here. Compression sounds like a much-needed feature, had not heard about that yet, and was tempted to implement my own. Thanks for the tip!

I don't have photoshop, just inadequate image viewers (irfanview, paint) that I used to build my own JASC PAL file in notepad. I may have made a mistake when I did that. either way, I managed to fix my issues with the screenshot and build a little demo cart that so far only shows the title screen. I needed some existing art with the correct palette to test my tools.

I'll investigate the correct palette again, and play around with these screens some more. Did you ever animate any of them? Making the dragon flame go across the screen like it does in the game would be cool.

I love this piece, spent a lot of time playing this game in the arcade when I was a kid, and a pico-8 port would be amazing (and way too much work, obviously). Regarding the palette, though: The gray background and the purple bar under the "select player" text seem like deviations from the pico-8 colors? As far as I can tell, yours are (138,138,138) and (114,57,81) but the console's colors are (95, 87, 79)  and (126,37,83) respectively?
