Hi Sam,

Thanks for the info regarding the fractional parameters, i was not at all aware that you could do that, although its usefulness is questionable when the much more powerful sspr is available. I'm finding lots of small compatibility edge cases like this as I go forwards. Currently I'm only trying to get own carts to run correctly, and haven't gone down the rabbit hole of other peoples carts yet.

My main reason for building this thing (I do need a better name for it) is that my new pico8 game needs to be able to save the levels that players create to solve the puzzles to disk, which cant currently be done with current pico8 implementation. Plus its a fun little project, its been a long time since I've written a sprite routine (Atari ST i think) . :-)

next on my todo list is
fill patterns
clicle drawing,
mouse support
sound.

Oh thanks for building z8lua, that saved me loads of time, if you had have made that I probably would have just used luajit, and not bothered with compatibility.

Cheers,
Lee
