Yeeah another great demo for my little PCE, sure with this code my 6280 processor will be heat for this winter !!!
Adding PCE console specific layer on top of that, makes for an interesting challenge (no, not a reference to Ys II).
OK, I've added an ISO of my demo: http://www.disgruntleddesigner.com/chrisc/data/FractalEngine.zipPlease let me know if you have problems getting it to work on your SCD systems.
