officially unofficial friidump 0.5.0
http://www.mediafire.com/?mzmyntwmowy

- Regions: Italy, France, Germany, Spain, Australia, PAL-X, PAL-Y.
- Updated publisher list from http://wiitdb.com/Company/HomePage
- Included GDR8082N & GDR8161B as supported Hitachi drives.
- Lite-On, Renesas & vanilla memory buffer access commands.
- Shifted methods 1..4 to 0..3 and added new ones 4..6
  Associated known drives with default methods.
- Additional commandline parameters:
  stop, speed, command, type, size

should work with most Lite-Ons, maybe other MediaTek based drives (Asus, Dell, Sony, etc.)
though ~1100 MB/h was most i could get out of mine
and it did need swapping

first thing to try to see whether it works on your drive
would be some PC DVDs - try it with all commands & method 0

if program can get seeds - buffer reading works
so you can proceed with testing methods 4->5->6->1->2->3

if PC DVD works and GC/Wii does not, your drive needs swapping

if you are going to swap DVDs, be sure to use '--type' or '--size' parameter

please report your results here

edit:
btw you can use CTRL+C to halt program's execution if something goes wrong
or it takes too long, etc.

update to v1.7.0:
- fixed sector buffer output
- rised parameter nr. to 6, for some obscure commands
- switched () and L1+R1 + () behavior, so now by default only set command will execute
- Start => CdFlush; L1+L2 + Start => CdInit
- set pregaps to different tone, so there would be audiable difference between gaps and tracks
added readme.txt with full description of keys
bundled with cdrX & sbi2sub into one single archive

great
thank you very much

oh, i'm very sorry, i forgot IsoBuster doesn't actually detect gaps, so there could be problems with CDs having CDDA
but you could use ImgBurn instead: .img should be fine for LibCrypt protected CDs, .bin for the rest
or you could check Create cue-sheet in CloneCD and throw away .ccd & .sub for unprotected games

hi hardrider
IsoBuster does not save subchannels, so it's only raw sectors (2352 bytes of main channel data).
this is sufficient for USA / Japan CDs, but for European (occasionally being protected with LibCrypt)
you'd need something more, e.g.
.ccd + .img (2352 main channel = IsoBuster's .bin) + .sub  (96 bytes from subchannels) from CloneCD, ImgBurn or Alcohol
unless, of course, when you know, that this particular European release isn't protected

sometimes IsoBuster might work better
but you'd have to extract data on multiple drives to be sure
and align it manually

we would have to address garbage at the beginning of gap anyway
but you could use reMove to cut off this gap and it should inform how many samples different from 0x00 there were
if this value coincide with predicted offset (from Plextor, swapping or just different drive), it's pretty safe to do 'psxt001z --gen'
in opposite case gap's content can be verified to determine further action

the garbage that is removed along with gap is nonexistent on actual media, it's an artefact of decoding,
always manifesting on data/audio boundary
you can tell buy descrambling it and it should form data sectors closest to audio data

have you tried changing your IP?

it's often enough to change MAC address
or sometimes it could be linked to PC name too

new version
http://www.mediafire.com/?nzmttnwi0ut

it adds CD unit control commands, since cdinfo.txt
http://psx.rules.org/psxrul2.shtml
http://hitmen.c02.at/html/psx_docs.html
and this document here
http://members.at.infoseek.co.jp/DrHell/ps1/index.html
were so interesting

so one can now retrive CD unit's chipset information, SCEx code from CD/Modchip,
execute those undocumented test commands, etc.

input besides to what's given on screen:
L2 - flip lower section
R2 - flip output buffer pages
/\ - set max value ($ff)
>< - set min value ($00)
[]+DPad - do things faster
L1+R1+() - execute selected command only (otherwise it's always followed with $1a)
this is sometimes neccessary, eg. for PLAY Command to work properly
L1+R1 + rest buttons - operate with Commands instead of Parameters
(e.g. if you'd want to swap CD you could use STOP command)
SELECT - change video mode
(i'm not sure if it works since all TVs i could get to support both PAL & NTSC but at least it will change resolution
basically video mode will be set on startup based on ROM detected so likely you won't need to use this at all
but you could try if you don't get an output for example)

chip IDs i get from my SCPH-5502 are:
CXD2545Q from sub-commands 23&24. it's servo system + signal processor,
so likely 23 is for servo & 24 for sp or vice-versa
CXD1815Q from 25. this is CD-ROM decoder
subcommand 22 return: 'for Europe'
subcommand 20: 97 01 10 C2, which @DrHell's page given above is described as Year, Mon, Day, Ver and it does look so

sub-commands 60 & 71..76 look interesting, could be they return unit's internal memory content

and please be careful with 00..1a - those control drive mechanics, like you can make it spin with tray open - don't do it
only interesting ones in this range appear to be 04 & 05

i mean your offset is 2 full sectors + offset from 3rd
it's described in guide

yeah, it could be F1ReB4LL, but if persond doesn't have Plextor and is not going to open drive up
it's the only thing left
