Trying to selfboot dc games with Internet

Heres what i did, i used cdirip to rip nfl2k1 full.
took the second iso (tdata02.iso) about (904kb) and took the ip.bin from my non selfbooting game and used ipins.exe ( from echelon self booting tools) to hack the tdata02.iso.
ok ripped the non selfbooting using isobuster placed it in my selfbooting data folder.
Then I used binhack.exe hacked the 1st_read.bin:
binary name: 1st_read.bin,boot sector ip.bin: msinfo: 0 (to be sure every thing worked.) placed ip.bin and 1st_read bin back into my data folder.
ran>
mkisofs -C 0,0 -V ECHELON -l -o data.iso data.
fired up cdrwin selected tools and record iso9660 image.
used data.iso for the first session (cdrom-xa, #####ed close and finalize session,open new session) then burned.
then used the tdata02.iso (cdrom-xa ) un#####ed open new session then burned. The game selfbooted, works fine but games with internet boot fine but internet option does'nt
work.the game returns to the play game music or vmu menu when you select connect to the internet. what do i need to do to get internet to work with this method ????????
