Two questions concerning exploit

Could someone plz answer these for me, I have searched and cant find a straight answer:

1)How do you make an ELF file boot automatically from Keylauncher or PS2 Menu K....(does an AUTO=15 command or something do it,if so where do I put it)

2. Im trying to copy the exploit for a friend using a diff PS1 game than I have, Can I just copy my system configuration file with a different TITLE.DB (This has not worked for me) or is my system configuration file from my PS2 different than one he would have from HIS PS2 and I need his PS2 to make it work?

THanks for any help.

there is really no use in using keylauncher or ps2menu-k to autoboot an elf file, its a waste of MC space.

if you want to copy the exploit to your friends MC just copy the TITLE.DB & BOOT.ELF (whatever you need it to be) to the BxDATA-SYSTEM folder on his MC.
