Thanks for those guys who helped. I have redirected UDNL to host0: and now the HDD has started up successfully. However, the program terminates and gets back to rom0:OSDSYS for unknown reason, here is the tty log:

Which unpacked ELF did you run ?
- If that's the MBR ELF, did you patch it so it loads hosdsys.elf as pain (decrypted ELF) ?
- If that's the decrypted hosdsys.elf, did you run it with
Code:
hdd0:__system:pfs:/osd100/hosdsys.elf
as argument ?

And if you used the signed hosdsys.elf, does your target system support MagicGate decryption ?

edit :
USB Driver (Version 0.16.0)
USB Keyboard Driver 1.02
F*ck me, it obviously is hosdsys.

Yes, the hosdsys is run directly as host0:hosdsys.elf (I have placed the corresponding files to hdd0:__system and __sysconf). The UDNL in T10000 rom0 seems to be not compatible so the system hangs after loading that module. Thanks for the unpacked (1.0J decrypted) elf, I was able to patch a UDNL call from rom0: to host0: for a UDNL I have obtained from SCPH-70000 bios. The program now boots to HDD and USB drivers but terminate somehow in the middle to calls rom0:OSDSYS. Anyone knows how to fix this? Thanks!

I have also tried a MBR made by SP193 several years back. The result is the same.

It seems that I finally get the hosdsys to run on my T10K, with the following method:

Running the HDD Browser on the T10000
[/span] This may interest some of you, but I was doing it to debug FHDB. For reasons, it stopped being able to boot my copy of the HDD Browser. I modified its ATAD module a very long time ago, so I am sure it works... Anyway, running my program that loads a decrypted copy of the HDD Browser from the HDD yields this ominous line via dsidb, while dsedb is stuck in a loop around SifGetReg:
Code:
loadmodule: fname rom0:SYSCLIB args 0 arg
loadmodule: id 31, ret 1
loadmodule: fname rom0:UDNL args 11 arg img0:
loadmodule: id 33, ret 1

UDNL returned 1 (not resident)! It can respond!? How's that possible? What happened, is that the T10000's late ROM had UDNL's device blacklist replaced with a whitelist, hence the HDD Browser's custom IOP reboot stops working because UDNL sees the "img0" device as an illegal device. Note that although only "img0:" is visible, the full argument is "img0: img1:". There is a NULL-terminator between arguments for IOP modules. To jump over this wall, I manually loaded UDNL:
Code:
dsidb R> mload rom0:UDNL img0:

...got its address:
Code:
dsidb R> mlist
Id Begin End Size (Text Data Bss) Ver Name
1 830- 190f 10e0 1070 50 20 2.3 System_Memory_Manager
...
22 e7730- e958f 1e60 1cb0 1b0 0 0.0

...and set a breakpoint on that evil function, before starting the module in debug mode:
Code:
dsidb R> bp e7730
$BP3=0x000e7730 init=0x1 curr=0x1 # enabled, auto-init
dsidb R> mstart -d

It's a coincidence that the function exists at the very start of UDNL's text section. I cloned this module before, which was how I knew it exists there. As there are multiple images specified, it is easier to disable this function. This gets it to return immediately, with an "OK" as the return value.
Code:
dsidb S> as $PC jr $ra
dsidb S> step
dsidb S> as $PC addu $v0, $zero, $zero
dsidb S> cont

The browser loads on my DTL-T10000, with it being identified as a SCPH-10000. So easy, right? Now just sink in about 4 hours of trying to figure out why it did not work and add in cursing and swearing. I missed the part about "img0: img1:" and spent about 2-3 hours figuring out why its MCSERV module was missing (since its sceMcInit function was getting stuck at binding). -- THANKS to the assemblergames archive of a post by SP193

Does anyone know how to convert this code so that I can patch UDNL? Thanks!
