    true, it's without sound. But it is possible to hear an Audio-CD while playing a GB game.

    I guess Sony just wanted to have a futureproof system. And they certainly made the PS1 futureproof - for hackers.

    Some things that comes to mind when I think of the expansion port...

    BIOS bypassing
    The built-in BIOS will pass control to a bootcart before it does anything else. A bootcart can therefore help you bypass the main BIOS rutine, and instead call the BIOS functions needed to init the PS1 directly, and skip or replace functions you don't want. When the built-in BIOS was changed in the later PS1 revisions, so that one needed to do a double swap to bypass the copy-protection, some piracy-friendly bootcarts would not only stop the CD for you, but also let you get away with only one swap.

    Uploading and running code
    Caetla is far nicer than Yaroze for uploading code in my opinion. It is fast and requires no bootdisk. Running executables from the file browser is nice too.

    Debugging
    The bootcart can have code to setup COP0 to break on read/write/execution as part of loading an executable.

    Graphics ripping
    Press the reset button when you see something you like in a game. To key here is that the PS1 does not clear it's VRAM on a warm reset. The very first thing many bootcarts do is therefore to copy the VRAM into RAM. Then you can view the saved copy of the frame buffer (like it was at the time of reset) in a viewer util, transfer it to a PC etc. :)

    The Bung Multi Xchanger
    I think of the PS1 and CD-R media as the heart of Bung's MGD3 suite.
