conclusion 1
hmm.....that looks like how the ps2 save builder splits it into parts...could u pm me w/ the attachment of that...or u could just mess around w/ ps2 save builder and see if u could join the 4 parts
conclusion 2
try to open the gamedata file into notepad and copy and paste the code into an .xps file...
This save has a 22,000+hp castrol supra and a 877hp acura cl?
I used the PS2 save builder with an old gamesave. replaced the old saves files with those of your save, saved it as a .sps file and was able to open it with MK's program.
I went ahead and put your save onto one of my cards to test it, and had no problem with it. Everything seemed to play fine.
I am going to swap your drivetrain in the CL to 4wd and extract the files, let me know if you can get it back to your memory card and if the drivetrain swap holds. If so there shouldn't be any problem for you to hybrid with mk's this same way.
Correct, I replaced the files from an old save of mine with those that you posted, and yes the save builder will work with the nport extension as well.
