if the game is in cdi format, use cdirip to get the tracks.
if you get one audio track and one data track, you're ok. if it has many audio tracks you have to do some nasty stuff to make it work.
take note of the lba of the 2nd track (data)
isofix it:
Code:
isofix tdata02.iso 11700
now extract it using isobuster
copy the bootfile.bin (created by isofix) to the game dir (created with isobuster) with IP.BIN as the filename
now you have two options:
1. hack the 1st_read.bin and the other bin files with binhack or other tools, then do this:
Code:
mkisofs -C 0,0 -l -o hacked.iso -V "game label" GAME_DIR
typical GAME_DIR is GAMENAME_ECH or something like that (it was created with isobuster)
burn that iso file and that's it.
2. create an iso file with the same offsets as the first file:
Code:
mkisofs -C 0,11700 -l -o out.iso GAME_DIR
isofix out.iso 11700
the advantage of this method is that you can use this if you have a game that can't be hacked (skies of arcadia, ...)
the key of a boot-disc game is the IP.BIN. if you don't put it, you're screwed. also remember to hack the files.
of course replace the 11700 with the LBA you game has (typical values: 11700, 11702, 45000)
also check xeal.cjb.net, that site rules. it has many tutorials for this stuff.
