    I have a few MD protos I got in, and they have nothing across the
    eprom windows. I shut the carts tight again, but am wondering what
    kind of material to use to protect the windows. I assume normal
    stickers would be useless as they are transparent to light.

    Its *usualy* a special black tape (the one used to protect the UV-flashable pcb's).
    I have no idea if there is a "label" for those kind of tapes ... because if you buy cheap black tape, it may not be good ^^

    Anyway, the exposure to sun light need to be quite long before they will reset... That's why many protos just have a simple white sticker/paper :)

    I'm interested to know exactly the name/brand of those tapes, if any :)

    You can use absolutely anything, generally it's people use a paper sticker or electrical tape.

    Most ultraviolet light is stopped by any material, which is why people get tan lines. Electrical tape would probably work just fine for a very long time, especially if it's already inside a cart.

    Flash won't harm anything. EPROM erasers must apply a specific wavelength for over 5 minutes to erase.

    This is not enirely true. A camera flash can affect EPROMS. All it takes it erasing one bit to screw things up.

    When a friend was testing Frog Feast on a Jaguar, the game would crash when a picture was taken of the screen.
