PS1/2 Free mcboot problem

[snails1221]

I am trying to install free mcboot on my ps2 fat. I'm following this guide http://bootleg.sksapps.com/tutorials/fmcb/swap.php. So, I bought 007 agent under fire. Then I dumped the iso to my pc. I changed the size of driving.elf and switched it with the free mcboot one. Then I burnt the iso to a Memorex dual layer DVD+R disk. After that I took apart my ps2 fat. I took out the disk stabilizer for easer swapping. Turned on the game beat it to the first level and saved. Then I swapped the disks. When I swapped the games. The menu music stopped playing. Then I picked the second level and the screen turns black and the disk stops spinning. What did I do wrong?

I've seen YouTube tutorials that say you should instead take the disc cover thing that has a PS2 logo off then stick a credit/gift/debit card with a little piece of it cut out to move what I think is the stabilizer out of place, pull the disc holder out, swap discs, then put the disc holder back in and push the stabilizer thing back in the middle (sorry I don't know all the right words). I also saw someone do what I believe is what you are talking about doing where they booted up MOH: Frontlines, then quickly swapped discs after the PS2 logo and load FreeMCBoot.
