OPL-Launcher

OPL-Launcher reads hdd0:/__common/OPL/conf_hdd.cfg to launch $OPL/OPNPS2LD.ELF.

You can inject OPL-Launcher into APA using, i.e. HDL Dump:

hdl_dump.exe modify_header hdd<Disk Number>: <PP. Partition with PS2 game>

To do so, You must also prepare few files for the injection process:

1. Signed executable which You can make by this application

        kelftool encrypt mbr OPL-Launcher.elf boot.kelf

2. system.cnf file that contains:

        BOOT2 = PATINFO
        VER = 1.00
        VMODE = NTSC
        HDDUNITPOWER = NICHDD

3. Standard PS2 game icon. Just take one from game save and rename it to list.ico.

4. icon.sys file, which is not binary like in Memory Card case but fully text one. Example file, title0 replaced by game name, title1 replaced by Game ID and region (information from http://redump.org/):

        PS2X
        title0=ICO
        title1=SCUS-97113 (NTSC-U)
        bgcola=0
        bgcol0=0,0,0
        bgcol1=0,0,0
        bgcol2=0,0,0
        bgcol3=0,0,0
        lightdir0=1.0,-1.0,1.0
        lightdir1=-1.0,1.0,-1.0
        lightdir2=0.0,0.0,0.0
        lightcolamb=64,64,64
        lightcol0=64,64,64
        lightcol1=16,16,16
        lightcol2=0,0,0
        uninstallmes0=
        uninstallmes1=
        uninstallmes2=

5. You can use a combination of 2 partitions: <PP. Partition with PS2 game resources> and <__. Partition with PS2 game>. Partition names should only differ in the first two characters. This will add compatibility with BB Navigator / PSX DESR XMB users. <PP. Partition with PS2 game resources> will contain game resources, <__. Partition with PS2 game> is the game in HDL format.

Detailed guide for installing on PSX DESR / BB Navigator

1. Install the game with HDL Dump by using the switch -hide. If you already installed the game without that switch, rename the partition and change the first three characters to __..

2. Create PFS partition <PP. Partition with PS2 game resources>. The name should match the installed game name in the previous step, except that the first three characters should be PP..

3. Prepare signed executable (for example, by this app)

        kelftool encrypt mbr OPL-Launcher.elf boot.kelf

4. Put signed executable into partition from step 2. For example, you can place it in <PP. Partition with PS2 game resources>/EXECUTE.KELF

5. Create text file system.cnf, BOOT2 should be the same path as in step 4, only replace <PP. Partition with PS2 game resources> with pfs::

        BOOT2 = pfs:/EXECUTE.KELF
        VER = 1.00
        VMODE = NTSC
        HDDUNITPOWER = NICHDD

6. list.ico and icon.sys are the same as in the first part of this Readme. These files are not used in BB Navigator / PSX DESR XMB, but you can keep them if you plan to use HDD OSD.

7. You can now inject all files into PP. with that command:

        hdl_dump.exe modify_header hdd<Disk Number>: <PP. Partition with PS2 game>

8. Create folder res in <PP. Partition with PS2 game resources>. This folder will contain all resources.

9. Create inside res folder text file info.sys. Example file, title replaced by game name, title_id replaced by Game ID and region (information from http://redump.org/)

        title = ICO
        title_id = SCUS-97113 (NTSC-U)
        title_sub_id = 0
        release_date =
        developer_id =
        publisher_id =
        note =
        content_web =
        image_topviewflag = 0
        image_type = 0
        image_count = 1
        image_viewsec = 600
        copyright_viewflag = 0
        copyright_imgcount = 0
        genre =
        parental_lock = 1
        effective_date = 0
        expire_date = 0
        area = J
        violence_flag = 0
        content_type = 255
        content_subtype = 0

10. Place jkt_001.png and jkt_002.png in res folder. These two pictures will be used as mini-thumbnails for the game. It can be the same picture as used in OPL art. jkt_001.png used in BB Navigator, jkt_002.png used in PSX XMB.
