Hi everyone, i didn't know where to post this so i posted it here, i use gpack to compress my psx colection, i separate the audio tracks and convert them to flac but i have found two games that have some audio in the first track, these are MLB 99 (USA) and Fantastic Four (USA), i decompressed them and i am not sure if the data at the end of the track 01 file is audio and thats what gpack is converting to .tak or there is something else like a bad dump. Any thoughts? I hope i was clear enough any help is welcomed.

Thanks for reporting this. I checked those dumps and the last sector was scrambled and did not contain the correct data. I've fixed this by running psxt001z --fix on the data track and then using injector.

psxt001z - http://redump.org/download/psxt001z-0.21b1.7z
injector - http://www.mediafire.com/file/bmv7lavdg … r-0.1b.zip

I guess we should do a thorough recheck on all the other multitrack PSX dumps to see if there are more dumps with this issue.

Is it safe to assume those tools produced proper track 1? PSX games don't have mastering errors?

Multitrack games with No EDC have ECC/EDC added in the last sector. This is a known bug in the Sony CD Generator software. Some drives aren't able to dump this sector properly.

I have compressed all of the USA games in the PSX database (except for the mia) but none show the same behaviour so i guess no other game has that issue but i am not sure, i don't have all of the japan and europe dumps but none of the ones i have has that behaviour, thanks for clarifying the issue.

I think we need some tool to mass-check the last sector for the noedc tracks.

Sorry for reviving this thread but i recently updated my PSX USA set and found some more dumps with the same issue as before:

Fighter Maker (USA) (Beta)
Thrill Kill (USA) (Beta)
Tony Hawk's Pro Skater (USA) (Beta)

Hope this helps.
