I need help dumping a psx game

[Devcon]

Hi, i don't know if i'm doin something wrong or maybe the disc or my cd-drive are damaged.

I purchased the game: "Attack of The Saucerman (E) [SLES-01718]" that it's in the database marked as blue.

I dumped the data track, and the first 20 audio tracks correctly, all have the same CRCs than the database, but the last track give me different checksums each time i dump it.

My drive has a read offset of +667 and can overread into the lead-in, and the game has a write offset of -647 so i assume i can dump it correctly.

Combined read/write offset it's -647+667= +20 so i'm dumping all the audio tracks with that value, but i have no luck.

I think i'm dumping it correctly? +20 is the combined read/write value right?

if it can't overread into lead-out there could be a problem since it has to overread into lead-out +20 with this disc & drive

you can use an over drive with smaller read offset to dump the last track

Ok will try, thanks.

I've checked this track and it should have a RIFF header in  the beginning

Code: Select all

52 49 46 46 C8 4E F1 02 57 41 56 45 66 6D 74 20   RIFFÈNñ.WAVEfmt 
10 00 00 00 01 00 02 00 44 AC 00 00 10 B1 02 00   ........D¬...±..
04 00 10 00 64 61 74 61 A4 4E F1 02 00 00 00 00   ....data¤Nñ.....

It's not a RIFF header problem, all the tracks there have a riff header and since other tracks match it can not be the reason.
And since the last track has many zero'ed data in the end there should be everything okay, dunno what the problem is.

Maybe it is better you upload your track somewhere to check the differences(?)

Even if his drive is unable to overread into leadout and there's data upto the very end, this can only result in some zeroed samples at the very end (the drive can't read them due to positive combined offset), but it shouldn't lead to different checksums every time.

Do the red dots in EAC light up when extracting the last track?

[themabus]

it's a surface defect then, i guess
those might pass as 100% good on EAC,
but tracks will differ among various drives, because of different masking strategies
and in some cases they might vary even on same drive, like in this one
cleaning or polishing surface might help or extraction with IsoBuster @low speed

[Devcon]

Sorry for the delay. Yes, the red dots in EAC light up at 62% to 63% of the last track, so i think the surface is damaged, snif i have bad luck. I also tried to clean the disc, but it don't work.

At least the game don't cost me much, only 3 euros

So can anyone upload the last track somewhere so i can get that game 100% complete please?
