Thanks meganova, I've managed to install FMCB to my Memory Card via the disc swap with Need for Speed Underground 2
All I did was copy an ISO Image of NFSU2 and download a program called Apache which edits the code within the image, in this case, I downloaded an uncompressed BOOT.ELF, renamed it to NTGUI.ELF and replaced it in the games code with another file named the exact same, except the file I replaced it with was uLaunchElf, this tricks the game into thinking its the right file, then I saved the edited image and burned it to a DVD-R.
After all that I booted vanilla NFSU2 in my PS2 Console and at the Main Menu, I swapped the disc with the other copy I made with a change in the code, did the special trick to activate uLaunchElf and then proceeded to install FMCB to my Memory Card, everything was fine and dandy.
Now, to transfer a PS2 Save Game to my Memory Card I downloaded a Resident Evil 4 Save Game, and proceeded to download a program called PS2 Save Builder, I then opened the save game in the program, created a folder using the same name as the game (BESCES-51719GAMEDATA E.g; It's region it came from) copied the folder to my USB Flash Drive, shoved her into my PS2, started FMCB and then booted uLaunchElf, from there I copied the files from my USB Flash Drive and pasted them to my PS2 Memory Card!
And then I reset my PS2 and threw in Resident Evil 4 and Wah-Lah! I had everything on both the saves!
P.S
I DID THIS WITHOUT ANY HARDMODDING OR SOFTMODDING (Didn't have to bypass sensors or open up PS2 etc.) JUST EDITED SOME CODE!!
Thanks for your help you guys.
Cheers
