PS2 OPL-Launcher cf70a22

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 a 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. Standrd 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 (replace title0/1 by target game):
   
   

   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=

Worth to mention that there is symbols limit which users can use in 'title0' and 'title1'. I'm not sure if I'm correct but it is probably 16 characters for first line and 32 for the second. Not many for full titles but this is OSDSYS and HDD OSD limitation.

Also, as alternative to use HDL Dumb, it is possible to inject files into APA space by uLE ISR HDD.

I try to keep the OPL launcher kelf in HDL batch installer updated.

So you can get it here

These KELFs are generated by a small script made by me that automatically Downloads latest ELF and converts to proper KELF via Alex parrado KELFtool fork

https://github.com/israpps/HDL-Batch-installer/blob/main/Release/boot.kelf?raw=true

Thank you! That's kind of like the automatic compilation of the PS2SDK or OPL! Automatic lib-updates included?!!

Thank you! That's kind of like the automatic compilation of the PS2SDK or OPL! Automatic lib-updates included?!!

Just a shitty script that I run before pushing updates to the repo (if opl-launcher was updated)

 

[TnA]

Sure... It isn't about the complexity, but the usefulness!

 

[jsnepo]

Anyone know where to download this? I don't have the means to compile one from Github.

Click the Assets to expand it and download (OPL-Launcher.elf):

 

[jsnepo]

Awesome! Thanks!

 

[El_isra]

Awesome! Thanks!

Remember that this ELF won't work!

You need to convert it into KELF!

If you don't know how to do it...

Here is one already converted

[jsnepo]

That's much better. Thanks! I converted all my HDDOSD games to use this and so far it works with most of them. I still can't get Ico, Twisted Metal Black Online, and Motorstorm Arctic Edge to work. I'll try and rip those games again.

Or just sing it by this tool (for MBR, but You don't need to cut the header):

ICO works for sure but it will hang if PADEMU is active.

 

[jsnepo]

Oh. Thanks for the tip. I try it again.
