Ok, now it loads the icons and the corrupted icon is a blue cube, the exploit does not launch, it goes back to OSDSYS.

Mmmm that's not a good sign, Anyway, replace fc 1f with fa 2f.

If this does not show a messed OSDSYS, then i'll need to adjust opentuna-tail.bin, but it'll be tomorrow.

Well now it gets stuck again before opening the MC. There's no hurry, do it whenever you can.

I really really thank you for the help

It's ok, I'm interested about you're doing in order to update OpenTuna payload sources. That problem is easily fixed by adding more zeroes to opentuna-tail.bin just by trial and error. Then, repeating the halving/doubling approximation sequence until it works. Actually that's how I tuned icon for different ROM versions in Fat units.
 
Well I should have gone to sleep but I couldn't let this go lol.

I managed to make it launch the exploit and I'm using the SDK's ps2-packer instead of the windows binary provided, even if payloads are larger in size. I then used the latest OpenTunaRLE with the latest "res" you sent and the resulting icon was tuned a bit in order for it to work.

Here's the normal icon:

Here's the tuned icon (just added F07FC020 as without tuning I was getting a messed OSDSYS):

icon_tuned.png

And attached you will see the two icons just for you to compare if you want.

I'll be updating my github fork with the changes I made.

After you guided me through tuning the icon I think I got what the idea of tuning is and well, I managed to do it.

Thank you very much for all the help @alexparrado !

Edit: here are the github repos for you to see the changes:

Really good news, I guess you're the third person I know who assembled a working hacked icon. Congratulations.
 
alexparrado updated OpenTuna with a new update entry:

OpenTuna v2.0.0: Fat models compatibility added and more

  • OpenTuna is now compatible with each PS2 Console starting from SCPH-18000 up to SCPH-90010 and PS2 TV. (ROM versions ranging from 1.10 to 2.30). Protokernels (SCPH-10000 and SCPH-15000) are excluded and OpenTuna won't be ported to them (at least by me).
  • Installer will automatically install OpenTuna, according to your PS2 model, in any of two MC slots.
  • Hacked icons were fixed to minimize hanging on...

one small question: the new opentuna is compatible with all these models as is? Because although it is currently working fine for me, I wanted to have this memory card as a exploit for many consoles if needed, not just mine and unlike FMCB, there is no option to choose between multi install or single install.

Once you install OpenTuna on MC, it'll only work on consoles with compatible ROM versions. For instance, if you installed OpenTuna using a 39001 model, that installation will work on any console powered by ROM versions 1.10, 1.20, 1.50 and 1.60.

As you mentioned multi-installation is not supported by current installer version. So, as workaround you can try manual installation by using proper PSU file according to target console, please check "How to Use" tab.

hi alex,
i need to do the following : i have ps2 slim with modchip but i need to install and launch opentuna from mc1 not mc0 automatically by using modchip. how can i do this?
Click to expand...
If you plan to use your modchip in DEV1 mode, it's mandatory to use MC0 to launch mc0:/BOOT/BOOT.ELF. In the case of Matrix chip in INFMAN mode file is mc0:/MATRIXTEAM/MANAGER.ELF. So,
  1. AFAIK mc1 is not supported in modchips.
  2. What behavior do you expect?
  3. Why do you wanna use OpenTuna if you already have a Modchip installed?
