Its tricky...look at Harper's Zelda code.  He's got some hacked routines that do sprites a little bigger.  8x8 is easier coz of
the bytes.

Ok, yeah...the numbers are just decimal values for binary like the first few bytes represent:

(128, 143, 214, 17)
10000000 10001111 11010110 00010001

....and yes, unless the person has A LOT of free time, it is pic83 generated.  You can find it on ticalc.org (try the search
engine...probably with no luck though :) or on Ti-Files.   Look under "Archives" then "Misc" or whatever...

Incidentally, hopefully I'll make a Win32 program that does the same thing soon...perhaps :)

HTH,

James.
