Good things are happening. I can draw some graphics in ASEPRITE, then feed them through a python script to convert them into raw bitplane data that I can load into the EGA graphics ram. From there I can do very fast VRAM to VRAM copies assisted by the EGA hardware. A full screen write can be 11-35 ms, depending on the CPU speed I have to play with. Hoping I can do something like Cosmo or Duke that has a parallax layer (even if that means el-chunky scrolling)
