Are those sprites displayed with a BASIC program, btw, or are they displayed with an ASM routine? I think somebody around here, with the help of others, managed to have complex sprites show up using line() commands, after being generated from a program. I wonder if it's very large, though...

Ya, I'm the one who helped MRide with the compression/decompression of the sprites. I wrote the different routines I made here
