Partially true. It does ignore/recalculate the CRC-16 checksum of the Q subchannel data indeed. If the Libcrypt game has only the Q subchannel checksum modified (majority of games have got both checksum and MSF data altered), it will not work on the PS3 without patching.
It looks like a display output blending issue. How did you set the display buffers? If you set the PMODE (0x12000000) register to 0x66, the blending should be turned off. Keep in mind with this particular setting you need to use a second display buffer (DISPLAY2/DISPFB2) for the output, as the...
I do not understand what is the point in downgrading the firmware, if it does look like a hardware problem.
1. Faulty hard drive - timeshift buffer does contain bad sectors, that could explain hard freeze during the playback.
2. Faulty RAM - the issue should not be PlayTV exclusive, though.
It...
Drawing functions in Snowblind Engine games (like a Dark Alliance) are tied to the VBLANK signal. You are forcing the 60 Hz video mode over the 50 Hz one, making the game run faster than programmed.
You have to insert a disc when the mmCM mode is enabled and try to dump the game. If it does not work (it will not likely), eject the disc, switch to the multiMAN mode and back, then try again.
Thankfully, there is a better solution - use a ManaGunZ instead!
PS2 ISO files dumped on the PS3 or...
Looks like the game does use code overlays. They could be loaded from anywhere on the disc. Moreover, they could be stored (in fact, they are likely most of the time), in the encrypted/packed/obfuscated form. You have to reverse engineer the function responsible for loading and unpacking the...
Looks like a disc read issue, not a software one. GT4 does read the second layer after the copyright screen.
Both patchers do not interfere with each other.
1a. PAL has got bigger vertical resolution than NTSC, so there is no way to display a full image without cropping.
1b. But a lot of games, especially from the Far East, are lazy ports. These games would fit the screen in the NTSC mode well.
2. PS1 consoles have got colorburst oscillators tied to...
The playback is unsupported most likely to avoid DVD Video licensing fees. The access to the DVD Video disc is granted by the MECHACON after decryption of a DVD Player KELF. But DTL MECHACONs have got such KELF files blacklisted in firmware.
It is not the newest patch that @LuanTeles is referring to. However, I am not able to port it to the other firmware versions as I do not have the 4.84 and 4.90 files. I could do it if you send me the modules first.
EE and VU0 run on the PPE because of the synchronization requirements. The quote you posted from the wiki does confirm that. Actually, both R5900 and VU0 recompilers and PPC emitter functions are reversed and documented by the one and only Mr. K.
