Very minimal changes have been done to miniBAE: I only changed what's needed to fix compilation issues and allow compilation to Wasm. I wanted to make sure that the output is as close as possible to the original code. That's why I used the original miniBAE C code (with some fixes) instead of porting things to JavaScript since I'd probably mess something up if I did that, especially considering this is legacy codebase and all that.
