HDL_DUMP 0.2a Readme by golf7


To start off with you need to place hdl_dump.exe and image.bin in the same folder and make it a folder that is close to the root of the disc.

EX: I have mine at D:/test/hdl_dump.exe


To run the program, DO NOT double click on the exe. You need to click
start, run, then type "cmd" (without the "&quot then hit enter.

THen navigate to the program file. Remember where you saved it. For me i would type:
(each line represents where i would hit enter at)

d:
cd test
hdl_dump

Ok now to the nitty gritty of installing games on your hdd.

to install games to your HDD, first hook up the hdd to your computer.
Then open up hdl_dump in command prompt and find out which disk is the one your looking for.

Do:

hdl_dump toc

and find the correct hdd that you want to install to.

next you need to execute this command.

THe inject_dvd comand.

Usage: inject_dvd device partition file signature

Creates a new HD Loader partition from a DVD.

Example:
HDL_DUMP inject_dvd hdd1: "Gran Turismo 3" c:\gt3.iso SCES_xxx.xx

so type :
hdl_dump inject_dvd [yourhddname] "[game name]" [location of iso] [SCES number]


p.s.
hdd name must be in:
hddX format
where X is a number.


SCES number can be found by browsing the iso and looking at the root of the folder for a file similer to this:
SLES_897.34



then it should create a new partition on your hdd with the game installed.

take out the hdd from the pc, and install in ps2, and enjoy your newly installed game with hdloader.
