But the fact still remains... The sound still cuts off during the cut scenes in Spyro 2 and Spyro 3, and I have Spyro 2 in CloneCD format, whilst I have Spyro 3 in .bin/.cue format. So I assume it's got nothing to do with subcode or whatnot...

Ok, I get it now. Thanks for the clear up and sorry for saying iso...

Yes I know that... but, since GoldenHawk reads the subcode, why doesn't it create another file, or for that matter, a bigger single file, since it will contain extra information? It just leads me to believe that the subcode data is already in the iso, only that you have to extract the subcode data with some special algorithm or something...

It wouldn't be the first time I never really understood the subcode notion really... I always thought that the 8 bytes after the header (subheader) were the subcodes... Now this is something I'm so damn confused about right now... Someone must be mistakened here, either you or Golden Hawk (creator of cdrwin) cause if you check this link, which is the feature list for cdrwin, you will see that it supposedly does read the subcode from the disc... Like I said before... I never really understood the whole subcode concept... I'm going to have to read the CD-ROM faq completely... If anyone is interested in taking a look: www.cdrfaq.org/My description of the EDC/ECC holds true for Mode 2 Form 1, if you add up all of the bytes you will end up with 2352 bytes of payload. The Mode 1 that you are talking about doesn't have subheader data, here is a quote from this site: "Such a high error rate is unacceptable for data or highly compressed video, therefore the CD-ROM Mode 1 format defined sectors containing a third level of software error correction. Every 2352 byte Mode 1 sector contains 12 bytes of sync, a four byte header, 2048 bytes of data, and 288 error correction bytes." But the PSX discs also have Form 2 in some sectors. You already know this but I'm just saying this for the sake of saying this... Mode 2 Form 2 discs do not hold ECC codes, only EDC codes. This will leave you with more space for the user data. I was mistakened when I said that the CD had 8 bytes of subcode data, what I meant to say was subheader... sorry 'bout that little misinformation... my mistake. The CloneCD format is comprised of 3 files: a .ccd which is comprised of a description of the ISO, a .img which is exactly the same as a .bin (you can try it out if you want to, compare a .bin and a .img of the same game and you will see that the bytes are exactly the same) and finally a .sub file which contains the subcode information. (which you already stated above...) And the question of the day is: If the .bin and .img files are exactly the same (down to the last byte... I just couldn't resist saying that), and GoldenHawk claims that cdrwin can read subcode data, then what is the .sub file from the CloneCD file format for? Is it just to speed up some kind of process which CloneCD executes at some point?

A) pSX Author, this is a fine emu you have here. Keep up the great work.
B) .bin files do include the subcode if you copy the CDs in RAW mode. Subcode information is not file format specific, it's a feature of the CD disc structure in itself. The Playstation reads CD-ROM XA discs, these discs are in mode 2, the beginning of one of these CD's frames is composed of 12 bytes of sync data (0x00, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0x00), 4 bytes of header data, 8 bytes of subcode data, 2048 bytes of user data, 4 bytes of EDC, and 276 bytes of ECC (Error Detection/Correction Codes). I know this because I did a study on the CD's structure for a project in college.
C) The .ccd files are just a description of the ISO, just a way to speed up the reading process.
D) This problem with Spyro 2 and Spyro 3, which also happens with Valkery Profile, also happens with me in ePSXe, PSXeven, and pSX. But it doesn't happen in xebra or SSSPSX (at least with spyro 3 that doesn't happen).
[EDIT]: And that someone haldrie described would be me.

it only cuts out the redundant edc and ecc fields, in other words the repeated ones, at least that is what I was lead to believe when I read the documentation that came with it...

Thank you pSX Author for fixing the bug

Sorry... The program just freezes... I enabled the status display icons and tried opening a file... but it still froze and no message or status icon appears. And this time I tried opening with a .ccd. Even .cue will not work...

I select the iso that I want to load and press ok and it freezes... the file dialog doesn't even disappear... I tried pressing the tab button to see the status but that freezes as well.

I finally was able to put a game running in pSX in linux... I had to convert the .img to .cdz to get it to run... otherwise it would freeze on me when trying to load the .img. It seems like a bug... I'm currenty using v1.12 at the moment... But version 1.11 also had a problem with loading the images. The linux distro that I am using is Ubuntu (UbuntuStudio and normal Ubuntu... it hapens in both distros)

i used apt-get install nvidia-glx-new to install these drivers, yes direct rendering is enabled (checked using glxinfo | grep -i direct), and the version of Guardian's Crusade that I am playing is NTSC, it worked in the windows version. Not sure if this is relevant or not, but I'm not using the version of pSX from the site... I am using a version that I download from a site that was recommended by UbuntuGames (has an installer... meh... tis for the lazy person such as I... ), but it is version 1.11 nonetheless.

I played this game on the windows version so it should work... It's Guardian's Crusade. I tried opening it with the .cue file and it didn't really help... I'll try opening the .ccd right now.
Still hangs... Could it be because of my graphics driver? I have an nvidia card... and I'm using the nvidia-glx-new drivers on UbuntuStudio... hmmmm... The psx BIOS animation goes without a hitch, and it shows the cursor (which it didn't do in the windows version... maybe because of the bios that I was using...) in the bios menu...

Version 4.0 (registered... not demo, not sure if results for demo are the same) is said to run pretty well in WINE, so I'm guessing that version 5.0 should run well as well, of course the last version tested was 4.0 in WINE 0.9.33 (if I'm not mistakened), they are currently in version 0.9.40 and a lot of improvements were made since then... If you want to check which programs run in WINE go over to appdb.winehq.org/ and search for it. BTW... set it to auto... still hangs... Does pSX support .img files in linux? (I'm thinking that it's a stupid question... but... meh... stupid would be to not ask)

I have not found a solution around the pad problem really... Now I'm trying it out with a different controller, which works alright, except that I have now found that I cannot load the game that I want to play... I try to load the .img file directly or the .cue file and it hangs... Maybe it's cause I have the subcode reading options at full... hmmmmm.... As for UbuntuStudio, yes it does have musical anotation programs, but if you would like to know which are the alternatives to Sibelius on Linux here is a site with a list of them and a description for each one to boot, plus a little comparison review: www.nabble.com/GPL-Scoring-Engraving-Programs-t3983617.htmlIf you would like to know straight off what it says, basically... There are no *great* alternatives to Sibelius yet on linux, although Musescore is the one to watch out for. UbuntuStudio comes with GNU Denemo and Rosegarden already installed by default, so if he would like to try out UbuntuStudio anyway and see if these packages are enough sufficient enough for him to work with, he's got nothing to lose... well... except for a little bit of bandwidth and a DVD... but that's not that great a loss BTW, with UbuntuStudio you have access to all of the Ubuntu software repositories, there are one or another that are deactivated by default but that is easy enough to configure. EDIT: Forgot to mention... If your friend does not like the alternatives he could also try to use Sibelius under WINE, it might work, if you need any help setting it up ask me and I'll give you some instructions on how to do so...

whoops... sorry bout that... not usually this careless when posting a bug...
I have a Compal HEL80 laptop with a Intel Core2 Duo T7200 + Nvidia GForce Go 7600, 2GB of RAM, 3USB ports, the gamepad plugs into the USB port. The GM-1500 is also known as the Predator, it is a gamepad that can connect to the PC and to the Playstation 2, it has pressures sensitive buttons and vibration, and it also has two analog sticks, it has a macro and turbo button. I'm using UbuntuStudio.
After trying the gamepad out with zsnes in linux I'm starting to think that the problem is not emulator related but driver related.
Sorry bout that...
EDIT: It's an Ubuntu problem... Again... Sorry bout that...
