Oh yeah. There is one more thing to that. DEX units have bit 0 set to 1 for the minor version. So you will never find a DEX with a MECHACON version number that is even. Thanks, but it is an emulator; the data retrieved from it, might not represent any particular PlayStation 2 model. There were a few MECHACON versions under the F-chassis. Based on the service tool, the CXP103049-101GG, CXP103049-201GG and CXP103049-301GG have a minor version of 0 (v3.0.x). The newer CXP103049-001GG-TL, CXP103049-102GG-TL and CXP103049-202GG-TL have a minor version of 2 (v3.2.x). The Asian (SCPH-30005 R, SCPH-30006 R, SCPH-30007 R) F-chassis MECHACON had a different model too: CXP103049-401GG-TL (v3.4.4) The small x is the MagicGate region number. SONY used this version number format to differentiate between the 2 G-chassis models, so that should be how it is done.
