I downloaded version 1.6.0 of epsxe. I got the Pete video/sound plugins. When I go to the FILE menu and run the BIOS, I get the Sony Playstation logo and the menu and stuff so I know my epsxe is working fine. However, when I pop in a game CD, it won't read the CD-ROM and I just get a blank screen. If I press ESC, it'll load me back to the epsxe main menu. I think I am not setting up my epsxe CD-ROM drive correctly. in the CONFIGURATION option, I set my CD-ROM drive to /mnt/cdrom. I even tried /mnt/cdrom2 (my DVD drive) and none of it works. What do you guys have for your setting for your CD-ROM drive? Help!

Your cdrom drive is not /mnt/cdrom. That it where it is mounted

You should enter /dev/cdrom

DUUUUDE!! You're a genius!! It works!!!!!!!!

What is the different between /mnt and /dev, by the way?

This explanation might contain some errors, if anyone finds anything wrong then please let me know. I am just presenting what I know myself.

Every device in Unix/Linux is represented as a file

/dev/hda1, /dev/cdrom, /dev/fd0 etc.. Go to the directory /dev/ and you will find a damn huge list of devices. Most of them might not be actually present in the system, but they are listed as a standard.

/mnt/cdrom is the folder where you mount the cdrom file system.
When a program wants to read a file from the cd, it will look in /mnt/cdrom and the OS will get the data from /dev/cdrom and send the data to the program.

Sometimes the program will need to read data that is not represented in the standard file system (things like the disc id in an audio cd etc..). So then it will directly contact /dev/cdrom and read it, just like the OS gets the information.

Usually when you insert a cd into your system, a program running in the background like autorun, will automatically mount the cd into your /mnt/cdrom.

You can also mount stuff like harddisk partitions of different formats. For example, I have some documents in a FAT32 partition. So when I need those documents through linux, I just mount it into a directory like /mnt/documents.

You mount stuff using the command/program 'mount'

check man mount for more information.

I think that information was enough for you to understand the difference between /dev/ and /mnt/

If you have any doubts then dont hesitate to ask.

lol! I don't doubt your knowledge of /mnt and /dev. Thank you for informing me of the difference. I appreciate it VERY much as I'm a newbie to all this linux stuff and am slowly learning my way around.
