If you ask me this,... I suggest you to send your MC to one of our installer-volunteers.
If you really want to do it on your own, just either post your list of original games here (somone might know if it works or not), or just search for other ELFs on the discs...
If none of your games contain any secondary ELF, you can try the double-swap-trick (which is even more time-dependent, than the single-swap), which should work with every PS2-Disc...
