I thought the same as you John, same hope sice pes3 ps2 and pc relase over year ago
ps2 had fevernova, pc didn't
nobody cracked mdl files, many ppl tried it at many forums
when pes4 was around the corner, Ariel messed with hexes and made smth what looked almost like Aerow but with many bugs unfortunately
we have no knowledge how Konami guys builded their mdl files, no chances to break it by yourself; you can open both pc and ps2 mdl's in hexeditor and compare and you'll only see milion of digits, no similar areas to copy and paste, like some ppl thought it could work
all different, all mess; manualy changing random digits and importing it to game, run the game, browse menus, start the match and see how ball looks like or crash
then back to hexeditor, change it back, change next value and import to game, run it, browse through menus, start the match and crash

after 20 you're enough tired or bored (or both) to continue and keep tracking the rest of 999.999.999 values you have to check, and then 1.000.000.000.000.000 of its combinations to be so lucky and find out how some ball areas start to be visible after changing which digits
it's could be a punishment for serial killers, not patching fun for editors you know
