This is the decompression result on the real Colecovision. The emulator show the compression working correctly and the graphic is perfect. On the real Colecovision, it seems it been interrupted or not complete the routine. The graphic loading routine is nested with the nmi enable/disable, so the pletter routine is running with nmi disabled. Does Pletter need the nmi enable to work properly? The decompression show different results every time it load the graphics. Anybody has this issue?
