Please use discretion when distributing this file. Sound ----- Uses the AY-3-8910 core. Stuffs up after a while. Hit reset to fix. Colours ------- The colours are similar to the original. Mainly the orange is missing, replaced by red. Other than this, the game appears to be perfectly playable. The current sprite/tilemap system has an x-direction granularity of two (2) pixels. As a result, all scrolling in the x direction is by 2 pixels - this will be rectified in later (64-colour) versions. T.B.D. ------ * fix x-axis granularity * colours Contact =======
