This repository is a follow-up to my earlier project where I explained how to use the PRINT command instead of the usual POKE to manipulate memory on the Commodore 64.
That trick made it possible to define sprites faster by printing specially formed strings directly into screen memory.
See my earlier created video on this here:

This time, no Excel macro needed!
Instead, the conversion is done fully in Commodore BASIC.
- The program takes a normal sprite definition written with
DATAstatements. - It automatically generates a set of BASIC lines.
- These lines can be saved to disk as their own program.
Load that generated program back, run it, and voilà — your sprite is instantly created.

I used the online sprite creator at https://petscii.krissz.hu/ to create a simple sprite as an example in the code.
From this online sprite creator I exported the definition in raw byte format and then converted it to basic lines. Replaced, by search and replace, 'BYTE' to 'data' en then copied it to CBM prg studio to add linenumers to it.
like this:
