No problem if it uses ioctl (sceIoIoctl/sceIoDevctl).

I tested ULJM-05105 (Stealth feat. Wipeout pure Stealth edition).

62256 + 380304 = 442560 (it matched layerbreak). So, there isn't a gap between GAME and VIDEO.

Does the resulting iso work as it should.
If put in ISO folder, does it work as a game.
And if you put it in ISO\Video does it work as a Video.
If so I would say you are on the right track.

It's not working on my hacked PSP3000 with 660 PRO-C.
Pressing the Note button does nothing, and the eboot version cannot be started because the data is corrupt.

changed: PSP_FW_VERSION 150 -> 661 (but I don't know this is correct or not.)

Does your tool dump these properly?
https://redump.info/discs/system/psp/status/3/
also, does your tool dump the same way as PSP Filer, or is there a chance that dumps with your tool are more complete?
sorry if any of these questions are stupid or already answered

Perhaps yes. I think these dumps are good because there isn't a gap between GAME and VIDEO.

I tested some discs by PSP Filer and my tool, and comfirmed same hash is outputted.
But problem is UMD VIDEO disc, not GAME VIDEO hybrid disc.

21504 + 421056 = 442560 (layerbreak)
But as you know, UMD VIDEO can't dump on GAME. So, 21504 sectors are undumpable.

I just finished dumping my (formerly user7/dizzzy's) copy of Stealth + Wipeout Pure.
Here are the output hashes:
ULUS-10058.iso 5ef803ca 386bfb26919a8f95d7300227b5b3d215 ea642afa63a3c36b7f55c407484ef4dc030cd5f2
Now what?
Also, sarami, you need to make this thing dump faster. It's too slow currently. It took several hours for my copy to dump.
(I'm attaching all output files except the 0B _mainError.txt file (because I don't want to upload an empty file
).

Hi,

I'll test it out. I'll try to give you the results tomorrow.
