MDS/MDF image

I hadn't put any thought into this til a little while ago when I read a thread where someone mentioned that MDF images should work fine with pSX.

I use Alcohol 120%, and today I made fresh images from my Final Fantasy 9 discs. Alcohol gives you two choices, CCD and MDS. I went with MDS first, but when I tried to start playing the MDS image, it just went to the initial black PSX screen that games do, and sort of froze, with glitchy graphics - SONY in big letters across the top, and discolored PLAYSTATION at the bottom, with no PS logo. The log window said something about invalid headers, if I remember correctly.

Then I tried converting to CDZ to see if that would somehow fix it. No dice.

Then, I got the discs back out and made CCD images instead. Ran them, and works perfectly, without anything even showing up in the log window.

What could have caused that? Are MDS images incompatible after all? The post I read that in was from a vet forum member.

Its no big deal to me either way, but I thought it was a little curious how pSX reacted to the two different image formats when they were both taken by the same program and from the same discs.

Not sure but MDF/MDS images should work fine as far as I know.

There should be no issue with using MDS/MDF. I've used a bunch myself with no issue. Never tried with FFXI though. What region is your game, and did you try loading the image directly, or mounted on a virtual drive? And did you try re-extracting the MDS/MDF images in case there was some random issue the first time?

I'm not sure of the exact region, but its the Greatest Hits pack that I bought in Wal Mart in the US several years ago. So I guess US or Region 1 or whatever.

I loaded it as an image in pSX, not on a virtual drive. I didn't try redoing the MDS image because I did CCD after the MDS failed, and CCD works fine.

I'll try to make MDS images again just to see what it does. What would the Invalid Headers error that it gave me suggest?

Tried again, and failed again. I think this might be a new incompatibility issue. Looks like an MDS image made for the Final Fantasy 9 discs (US Greatest Hits release) with the most recent alcohol 120% version (as of 04 May 2010), used on pSX 1.13, is incompatible, while a .ccd of the same discs with the same version of Alcohol is good to go.

The MDS/MDF image gives an Invalid Header error in the pSX console window.

Made a new MDF/MDS for Metal Gear Solid, loading that crashes pSX. So a confirmation of a problems with new MDS/MDFs.
