Round 1 TE.
Red IV Street Fighter Art work on the panel.
Issues with the PCB/ Main PCB
Round 2 TE
Alternate SF Art work
Used as the basis for other Mad Catz themed TEs Including Marvel vs Capcom 2, Marvel vs Capcom 3, BlazBlue, Street Fighter Fem Fatal, Comic-Con TE and the Gold Evo TE.
The White (Asian) TE is a Round 1 TE
Other themed TE sticks are mostly the TE-S including the limited edition Chun Li, MLG, Soul Calibur V and Tekken Hybrid.
Both the Round 1 and Round 2 sticks are discontinued
What is still being produced are the TE S+, The Pro and the V.S. sticks, all with improved body construction and improved PCBs from the Round 2 and TE-S sticks.
Note I posted sticks that are purposely left out of the guide as they are limited edition collectors items.
