These are the requirements if you want to help me (if you don't know the stuff that I'm about to tell you, and can't/don't want to learn, sorry but there will be no way to help)
1) You must know how to reverse engineer software. (This includes ASM / processor level knowledge (like registers, stack, etc), using disassembler / debugger / hex editors, and knowledge of the Win32 platform / API.)
If you don't know how to reverse engineer, but would like to learn, PM me and I'll put together a guide. (It is preferred that you have some experience programming in Windows with a common language, like C++)
2) If you have knowledge of OP2, like file formats, OP2's internals, etc. (A good example of someone that doesn't have a lot of Windows programming knowledge, but could help because of his in depth knowledge, is someone like Kevin Ar18.)
3) Someone that is REALLY willing to learn technical stuff (like #1 above). If you are them, you should have a LOT of patience, and be able to understand complicated stuff (like technical aspects of a computer). If you (still) apply, PM me and I'll give you information.
Well, there's my "requirements". Of course I'm sure you can help out in other ways OP2-wise if you don't want to / can't meet the description(s) above.
