PSX Switching ISOs

This has been giving me problems for days and days I cannot find a fix.
I've been playing MGS on an emulator, everything was perfect until I got to the end of the first disc and then the nightmare started. For some reason, with none of the emulators I try, I can't seem to be able to change discs. ALL and I'm saying ALL the emulators I tried crash as soon as I click on the "Change Disc" feature.

I tried at least 4 different versions of the game from all around the world, I tried .bin and .iso, I tried changing emulators, I did literally everything I could do but no matter what it's still not working.

This is making me so mad I feel like I might explode in a murderous rage.

Why is this happening?

Can anybody provide me with a savefile on disc 2 so I can just bypass this?

Bump, please.
