spr2bbc
A BASIC program (and C equivalent) for converting RISC OS Sprites to raw files suitable for loading into BBC video memory. The C version is undoubtedly faster, but completely untested. Usage:

spr2bbc <infile> <outfile>

Accepts 1bpp, 2bpp, 4bpp sprites as input; only the first sprite in the spritefile will be converted.

Hi, having a problem with spr2bbc BASIC utility after trying to write a BASIC program with Copilot to complete the same task.

This is the result of using the command from RISC OS ARM BASIC V,
There is no documentation but the description from above is all I can find on it. At least the program finds the sprite DCASTLE and reads the size.

Anyone know what this error means exactly? I don't know about "packing Sprites" into words yet.
