I have a copy of SD Snatcher for sale on eBay. It ends in 2 days.

You can find it here eBay link

Could you elaborate on 'disk 1 and 3 don't have "Konami" on the shutter'?

take a look at the pics not the word konami on the metal slit

The disks were like this when I bought the game a few years ago.
I don't know what the previous owner did with the disks.
I think it is important enough to mention in the auction text. If you expect a mint copy, you don't want to buy this one.

fair enough IMO....

I've bought a few disk games second hand... while both seem to be entirely complete/original, disks are a problem anyway since the chances they'll stop working eventually is a lot bigger than with carts, or cd's..... same with tape games. Simply put, some of those disks make scary noises when I put them in my MSX, but they still load up.
Well, that's a risk with disks I guess most people know about. At least it's possible to replace them quite faithfully*** if they ever give out, which is harder for Cartridges, CD's and Tapes. And even then, this particular ebay auction still comes with box and manual and all, which is at least half of the value, if not more.

***as long as one can preserve the disk sticker, it's possible to write an image of the game back on a different disk, and you won't even notice it wasn't the original anymore. Of course, in this particular case, they could still be the original disks, maybe they never had a logo (seems odd, though), or just the shutters were replaced. There's simply no telling...
