Guys! I finally figured out how to hack the binaries using Hex editor! 👍
and it works!! Here is the method I used ... and I tested with HD Loader
method:
1. use ISOBuster to extract the iso or burned DVD-R
1. download AXE from here
http://www.jbrowse.com/products/axe/download.shtml
2. install it and run it
3. open PCPX_966.49 file with AXE
4. look at offset column and scoll down to 001F0740
5. you will see that row like this FF FF 42 24 07 00 40 14 .... and you change the first 8 digits to FF 00 FF 00 .... then that line should be FF 00 FF 00 07 00 ...
6. Save and overwrite PCPX_966.49
7. repack all files and burn
to Repack (for swap magic user or your ps2 is very picky)
I use $ony cd/dvd-rom generator > New Project > DVD Master Disc
volume set to GRANTURISMO4, Disc Name PCPX - 96649, others blank
in Directory, drag files into the program in following order:
SYSTEM.CNF
PCPX_966.49
IOPRP300.IMG
IRX (folder)
EPSON (folder)
GT4.VOL
then press record, error show up(ignore), export image and save file name as GT4DEMO
after that you should have GT4DEMO.000 GT4 DEMO.001
then use command prompt (Dos mode) and go to the folder where GT4DEMO.000 located
type this: copy /b GT4DEMO.000 + GT4DEMO.001 GT4DEMO.iso
wait a while, you will obtain GT4DEMO.iso in the same folder
use Nero or DVD Decrypter to burn the iso image
then now ... you can enjoy Nurburgring without time limit ... YAY!
