using a custom tileset as a fixed-width font for _PrintString ?

[madscijr]

Wouldn't be terribly difficult to load a copy of that tileset in RAM then write a SUB to use it as the string characters using _putImage

That's what I've been doing, but with changing the color on the fly, it can get slow. 
I know hardware images are a way to speed it up, if you're willing to pre-generate a giant tileset with all the different color combinations to copy the image from.
It's been a while and I don't remember exactly how to do hardware images but it was less simple than I would have liked... 
Anyway, thanks for your reply.
