So, manuel, have you got the latest version of the script?
Yes, it's in openMSX git. So the latest development build provides it.
Wouter implemented the SAT stuff as it's done in the openMSX code itself, which is what Grauw wrote, basically. It works pretty well now. Except for screensplits. I have a prototype that allows you to specifiy which fraction of the frame the VRAM/VDP data must be sampled at.
Please try it the current version, from the development build or directly get the changed files: https://github.com/openMSX/openMSX/commit/6a9bbf65326a4fa77e...
Thanks it is great tool to debug some tricks
You're welcome! It was a fun thing to do and I learned something about how sprites work (I'm not really a very experienced hardcore MSX programmer...) If there's anything else you need, always ask, perhaps it's another fun little thing to create.
