Are .mds files required for emulation?

[jobson]

Hi there!

Dumb question, but:

As far as i know, .mds files contain the "whereabouts" of the layerbreak. I'm emulating a couple PS1 games on PCSXR.

So, i just wanted to know if the .mds is considered useless in this very specific case.

I would say so.  PS1 games were on CD where layer breaks weren't a concern.  However, I can't recall seeing .MDS ever associated with a PS 1 game CD image.  Of course, I'm just going by ImgBurn, which I can't remember that it used MDS in its file set, but maybe it did.

Guess you're right. I'm emulating Sillent Hill rn and it works just fine, aside from a couple stutters here and there.

As you can probably tell, english is definitely not my first language, so i apologize for any grammatical errors.

Thank you for your assistance, have a wonderful evening.
