Nice work Retro-Nerd, the PC Codewheel works
I've now grabbed screen shots of the level codes access screen for the original retail SPS English + French versions...
So in conclusion;
all SPS versions have different level codes access screens to the the Crystal crack. However the Crystal crack is virtually 99% perfect english, just slightly hacked I guess which is no big deal really.
Edit: just took a look at the screenshot and it looks like the English one was soemhow posted twice
Fixed now...
