It's possible that the LEs at TPF may have been running updated code that hasn't been publicly released yet (which would explain the more frequent disc spins).

Anyone ask them about the software version?

Yes, on the LE the upper orbit gates open up for a Ref Scoring mode. It's pretty awesome, especially when you can consecutively hit ramp after ramp.

Yes, the other belts are in there, but it's frickin' hard as hell to progress further than US Champion at this point in the code (I had to take the glass off to verify the other belts were there).

See the excerpt below, taken from Rcade's WWE Code thread:

"-----CODE OPINION-----
- Game is WAY too tough to progress as it is, which I think leads to a lot of the unsatisfying gameplay for come players. For instance; in order to start the Tag Titles match mode, you have to first play all the way through TagMB (by hitting each lit shot twice, then hitting a roving JP, then hitting the pin scoop for the SJP) and then after you get the SJP in that mode, you have to end to mode by draining out of it, then start TagMB AGAIN in order to start the Tag Titles match mode.

After you start Tag Titles mode, you should also qualify the Royal Rumble (IC Title) mode for when you end the Tag Titles mode, assuming you've already won the US title. You have to progress through the Tag Title mode and get the SJP in order to win the title."
