Thanks for the response.
I extracted the files with isobuster and made an iso (lba=0) keeping the original file order with a sort.txt.
mkisofs -C 0,0 -V "DRIVER" -sort driver.txt -l -o driver.iso driver
I burned that iso as the 1st session with cdrecord like this:
cdrecord dev=x,x,x speed=4 -multi -xa1 driver.iso
cdrecord dev=x,x,x -msinfo
Then I made an iso of the bleem.bin using that lba, inserted the IP.BIN and burned it with:
cdrecord dev=x,x,x speed=4 -xa1 bleem.iso
That's it... A selfbooting PSX game for ur DC.

Also, you can use this same disc to boot any other PSX game by doing a soft reset without the disc in the DC. It will flash the bleem! screen and u pop in any other PSX game.
Thanks for checking on that. So far I've tried using my brother's disc of Driver and my own disc... same thing with each. Never checked for a version tho.
