I decided keeping multiple codebases was not productive at all. I've consolidated my code into a single, fairly easily expandable code base.
Right now, it only supports 128 bit hashes, but I intend to expand it soon to support larger hash sizes (out through SHA512).
However, adding hash types is fairly easy (write the code using the others as a base, then add it to the function pointer lists). As of now, it supports MD5, MD4, and NTLM. All in a single binary.
Hopefully I can release it today. I need to debug some serious issues with Windows, though. The previous versions were doing a mix of crashing and bluescreening systems - not good. It's also not particularly happy on very low end GPUs right now.
//EDIT: Released!

Currently supports cracking: MD4, MD5, NTLM.
Platforms supported:
Windows XP (32 & 64 bit), Windows Vista (32 & 64 bit). Untested on Windows 7 but probably will work.
Linux (32 & 64 bit)
Mac OS X
Requires an nVidia 8000 series or higher GPU, CUDA drivers.
Peaks at around 30B compares per second on a sufficiently large hash list with a GTX260.
Improvements are in the works.
