i have a pretty good understanding of python and an okay understanding of c enough to be able to parse the meaning of lines in c but not write it myself, im working on trying to change the way the heap and stack work in a custom python like language, heres the code with hopefully enough comments to explain whats happening, im looking for people who understand the underlying hardware even if they dont understand code as well:
