Yep, I was part of WildC*rd. I mainly worked on reverse-engineering the patches Dark_AleX placed on Sony's modules to make things like Pops work.
I also made the flasher, reverse-engineered the DXAR format, and integrated our flasher with the DXAR builder.
I was also 100% responsible for every update after the first release, the flashers for the updates, and the code for checking the current version and file integrity ;P
Below are the source code and descriptions for what was changed in 3.40* v2 and 3.40* v3. I figure that enough time has passed since their release that nobody would be too pissed if I shared them :)
You can get the ORIGINAL source files here.

To the rest of the team: It was absolutely a blast working with you guys. You're a smart bunch of folks and I'm glad we did it, even if it turned out semi-disastrously. Wish we'd finished 3.52*...
