A new video of parallax scrolling, with a significant speed increase.
With an upgraded ZEsarUX emulator, and a little bit of newly gained know-how about ZX81 BASIC compilers, a machine code version of the "PARALLAX" demo was created.
"MCODER2" is an easily available compiler, and basically just two USR calls (via LET) are required to do the compilation. There are a few limitations to what BASIC code MCODER2 can handle, but interestingly it looks as if in this case none applied. (See MCODER2 documentation, and source code in the video.)
Anyway - the increase in speed is quite nice. :-)
