"Why do you want to compile it from source files? There is binary right next to them http://dlcorp.nedopc.com/download/file.php?id=3013 You can run it just executing "unreal.exe"... or "wine unreal.exe" if you're not using windows..."

I prefer to be able to rebuild the project, so I can also debug it or modify for experiments... but even bigger issue is the "exe", I don't have windows, and my "wine" config is kinda flaky and broken, as I don't use it very often and can't remember what experiments I did with it, but I can't run windows executables easily... Anyway, it would highly likely take me at least half a day to make it work and to learn how to use it, probably whole day.

So it's quicker just to take a look at the source code and let *you* confirm if I understand correctly how it works

The new info is perfect, now I'm sure the code I have seen is used, and I did understand it correctly, so I know how to produce working bpx.ini from sjasmplus.

If you will pull latest sources of sjasmplus from github, it's now implemented.
(check the last commit and new asm test files to see the usage, the docs are not updated yet... next thing to do)
