I want to ask a question regarding downloaded PSX isos(.bins, .imgs....)

Okay, when I downloaded the Megaman X6 rom, there were two files(bin file and cue file) within the zip file.
I'm using the ePSXe latest version emulator.Question:
Do I need the .cue file(76 KB) to play because when I play I just run the emulator then select the bin file and it's ok?
What's the significance of the .cue file or .sub file?

The .cue file (open it in Notepad) just contains the layout of tracks of a CD. It is used when you want to burn the image onto a disc. You burn the .cue instead of the .bin then :) So, you don't need it unless you want to burn it later on (otherwise you could just still use the .bin).

okay thanks, what about the .sub file, it came with the Resident Evil 2.img file(not bin file)

.sub??maybe for subtitle??
I just extract all inside the rar/zip file into the folder and play..

Okay then. I needed to know because my PC's getting cluttered and I want to clean up.thanks for the help.

.sub is subchannel data, usually audio.

oOo..you cleaned up manually??

What do you mean by that?

Loonylion · #6.sub is subchannel data, usually audio.

So it isn't okay to get rid of the .sub file?

Not if you want sound I guess.

The files are so tiny, just keep them all. There's really no reason to delete them (What is 75kb compared to 700mb?)

^Has a point :P

I guess,

haha..
I mean..did you manually clean up your computer without using any software??

^No,. of course, not

Another Question:Is it okay to rename the files I downloaded, well except the extensions, E.g fft.bin ---->>> Final Fantasy Tactics.bin?

yes,but all the files need to have the same name...
