That's a neat idea about exporting an 'Install' function!

I've actually been working on simplifying my project using macros similar to how you did (except in the assembly), which has made it much easier to maintain compared to before. I also fixed the "random" crashing bug that I referred to earlier (which was caused by stack corruption and some of the volatile registers getting mutilated by my proc resolver function ). If you or anyone else is interested in taking a look, here's an example of the changes I've made:

Edit: OK I really fixed the register mutilation now... I was restoring r8 to r9 and r9 to r8 in the last commit.
