Redump Forum

<r><QUOTE author="superg"><s>[quote=superg]</s>Hmm, I'm not familiar with .LSD, probably not from redump. I can easily generate anything from redumper output, .SBI is lame, but that's the only way we can have it right now.<e>[/quote]</e></QUOTE>

I don't know who has invented that .LSD format, but ...

<r><QUOTE author="superg"><s>[quote=superg]</s>Hmm, something doesn't add up here, for Medievil (<URL url="https://redump.info/disc/592/"><s>[url]</s>https://redump.info/disc/592/<e>[/url]</e></URL>) I have the following sectors with subchannel errors: ... They don't match your first table.<e ...

<r>Cool. I don't know what dumping tools you have, but most should work as-is, or with minor modifications.<br/>
<br/>
1) Dump the sub-channel data from the whole disc, and create a list that shows which subchannel bytes are wrong on which sectors. You are probably already having hardware & software ...

<r>I've already posted this in <URL url="http://www.psxdev.net/forum/viewtopic.php?f=59&t=4176&p=23041"><s>[url=http://www.psxdev.net/forum/viewtopic.php?f=59&t=4176&p=23041]</s>http://www.psxdev.net/forum/viewtopic.p … mp;p=23041<e>[/url]</e></URL> but I thought it might be interesting here, too ...

Yes, the "SC4309xx" names on the 52pin chips seem to be unique for each version/region. The older 80pin chips do probably also have some unique names ...

<r>The PSX is using a small 8bit Motorola CPU with onchip BIOS ROM to control the CDROM drive.<br/>
The first BIOS dump was done some months ago via decapping: <URL url="http://wiki.psxdev.ru/index.php/SUB-CPU"><s>[url]</s>http://wiki.psxdev.ru/index.php/SUB-CPU<e>[/url]</e></URL><br/>
And that dump ...

<r><QUOTE author="Nexy"><s>[quote=Nexy]</s>Alcohol supports ISRC, this stuff is encoded in sub channels in mode 0 sub channel entries (normal ones are mode 1). So basically any image with valid sub channels can have ISRC codes.<e>[/quote]</e></QUOTE>

Yes, that would work. But only if the .MDF files ...

What is a redump image? Another file format?

<r>Rok (the libmirage guy) has tested .mds files with more than 9 tracks some days ago. The track numbers are non-BCD (which solving my main question about the format).<br/>
<br/>
He has also made some .mds/.ccd sample images with ean/catalog, isrc, cdtext, more than 2 indices and multiple sessions ...

<r>About the 2nd and 3rd variant of M3S files... I think they are just nonsense.<br/>
For example, for the SLUS-010.51.M3S file, according to <URL url="https://redump.info/disc/259/"><s>[url]</s>https://redump.info/disc/259/<e>[/url]</e></URL> the SLUS-01051 disc doesn't have any libcrypt protection ...
