Open decrypted psx emu elf in hexedytor and search for "disc". First you get "%s/disc/disc0" its path for mounting virtual drive without checks. You can specify here disc for mounting(iso with header from bishi bashi). Next will be "pfs0:/disc/disc%d". This is for validation, so it must be specified to original disc0 file. That's all.

hmmm.. i was trying to make custom images by adding header from bishibashi (exactly 1 Mb), but it seems not working (i was trying this game - can you please check it?). So now will try silent hill...
With original disc0 anything is working fine :)


Yep Silent Hill works fine :) Thanks for this stuff!!!!

This is beginning of Header file (1Mb) combined by 10 bytes

In offset 400h there is SPOP word :) and image size in sectors on offset 406h (twice). The same that in offset 9368h in original CD image.


It seems that there is Country-Code Lockout for Japan consoles, right?


Emulator uses latest bios from SCPH-103 v4.5 J (there is no dump in community - so it will be useful not only for PS2) so it seems that it really use region protection.

Re: PS2 HDD Dumps
 

I replaced bios file to scph7502.bin and I was able to run PAL games (there was even boot sequence). I dont know if there is region free bios but we can always patch image region.

Ответ: Re: PS2 HDD Dumps
 

thanks )) unfortunately i can test games only on evenings. To my mind it is not good idea to replace BIOSes (cause 4.5J is the latest), it seems that patching images is much more useful (but it is great that bios replace is working).
So if understand correctly we don't need to change sector count in 1Mb header at offset 46h? Anything is working fine without changing? Pal game runs in PAL video mode?
Maybe we can replace %s/disc/disc0 with %s/disc/disc%d to add possibilty to run 2-disk images? Did you try to boot directly into bios?

Re: PS2 HDD Dumps
 

I didn't change sector count and games run fine. I only tested ntsc FFIX(at battle are disappearing some characters) and Silent Hill (some slowdowns but works good). When I run pal Diablo it freezes in loading screen (probably copy protection).
Emulator always run in NTSC mode. If you want it to run in PAL use GSM from psx-scene.
Replacing %s/disc/disc0 with %s/disc/disc%d wouldn't work. I tried boot to bios with normal image(without header) but it hangs. Soon I will try with cdaudio.

I was trying to launch Crash Bash Pal and it shows me some graphical bugs and when i try to enter the game it freezes on Loading screen...


It seems that there is really copy protection modules.

Sorry, been busy as hell.

MUAHAHAHAH. It was that simple ?
Awesome find ! Thanks very much for sharing the info:ng_ThumbUp:.


@ AKuHAK,
Sorry for not replying to your 2 private messages. I was about to write a reply but I saw you answered your own questions, and all the great progress in the thread...
Thank you for posting the bnver history/changelog. Never heard of something else than "Pre-Release" version (SCPN-60101) for PSBBN 0.10, and I've been told it has no online upgrade capability.

Well I did a packet capture and URL snooping of the PSBBN 0.32 first initialization. Since you've detailed the update process, it's useless to share but here I go :

The dump of the GameCity Channel you've asked for :

Kudos to Richi for archiving. I just made little modifications here and there. I don't know if it can be run straight from opt0. At least it works fine from local host/dedicated server. Oh and it's not a recent backup, I can't remember when it was done.

Regarding CogSwap, ZoneLoader or any 3rd Party tool, I'm affraid it's not possible. The installer tells to remove Disc 1, insert Disc 2 and rejects wrong discs. There is no poweroff/reset, the second disc have to be inserted and validated whilst the installation program is running. Single-swap method does not work, even if the TOC is refreshed. That shit can not be installed on unmodded units.
I sent my cracked backups to the trashbin :( . Can't make new ones for the moment because I'm working on the "MRBew Loader" project.

If I find the time, I'll release cracked Utility Discs so someone with a modchipped console can intall it and share the HDD dump...


Or perhaps just a glitch.
Any feedback on how the commercial game emulation is ? The tests I did a while ago with homebrews were disastrous (glitches, random crashes and shit). Some couldn't even start.
