Silver SNK Warranty/Serial Number stickers on old MVS carts

Do these stickers leave a VOID residue on the cartridge if removed? What I need to do is peel the sticker back to get at the PCB's inside without harming the sticker. I want to keep it as intact as possible.

Thanks for any info!

It still may leave a mark, (I know Sony stickers do) but if you get a hair dryer and heat up the sticker, it should come right off. It doesn't take long, where you have to apply too much heat.

If these are standard stickers, then it should peel off while remainding sticky on the back.

Sweet I'll try the hair dryer idea

although if you're just checking for boots those stickers are a surefire way to know that they're legit...

I've wondered about those. I've got some carts that have the foil SNK warranty sticker on the side with what looks to be a serial number, but this number does not match the serial number on the label. Is this like a number that may represent a date of purchase since the foil label states a given amount of time the cart is covered under warranty?

Could be a repair label.

You can still buy these?

Depending on where the sticker is.I sometimes just try to lift the case open on one side and finagle the boards out..to not break the sticker or label.(if removing the boards for cleaning)
It's hard to do but I've done it..

If I'm checking for a boot I try to peek inside using flashlight by lifting the case open on one side.

What I have done on some of my old MVS carts with security labels is slice the label with a razor in the line that seperates the case.(neatly)
This way the sticker is still there,it's cut but not peeled....If I'm going to be opening a cart often/problematic cart etc then heck with the security sticker.
Some carts come with them and some don't,..If the sticker was removed who'd know it was actually there once.
As long as the boards are real to me.....
And I never fully open a nice labeled cart so I don't crease the label..

Me....If I'm to sell a cart that was has a possibility to be a booted cart I'd rather open the cart,take a picture of the boards and very it to be real/original..
Thus a security sticker depending on where it's stuck on the cart can prevent that...
I'd rather I know a cart was real when it was purchased from me..

Surely flashlight + windowed eprom = bad

Isn't it UV light, which is bad?

Yes. A short peek with a flashlight won't do anything. But leaving your PCBs on the dashboard in the sunlight.....

I'll have to try and remember not to do that!

Wrong - glass is a very effective UV filter as I learned in my A-level physics.

some flashlights will emit UV as part of the spectrum they produce.

You failed to mention these UV torches originally though John.

As it turns out plastic (such as in a flashlight lens) is a MUCH better UV filter than glass. You will get sunburn through a windshield or any window in no time flat.

Glass is not nearly as effective at filtering UV. The lens on a EPROM is glass. Sunlamps use glass. The lens on a UV lamp for erasing EPROMs is glass. The UV chamber on a HPLC which uses UV detection is glass.

So, while glass may filter a tiny bit of UV light, it is largely UV transparent.

There's an easier way to do a quick check for boots, not sure fire but works alot of the time. Grip the cart in both hands infront of you label up and white arrow facing you. Flip the cart around 180 so you are now facing the back. Tilt it forward and look through the vents. Of course you need to have some sort of light, but you should be able to see the chips on the back pcb.

Minor correction here. The window on an EPROM is not glass, it is quartz crystal and normal sunlight isn't very effective for erasing it. You need a certain wavelength of UV light to do it within a reasonable time.
