The one I have did not come with a boot disc and it did not need the disc to operate. It is truly plug-and-play right out of the box. It is basically a memory card at double the normal capacity (at 16MB) with an expansion slot which allows you to plug your original memory card in there. A switch on the card allows you to switch between the 16MB expansion and the 8MB memory card. There are 2 LED indicators that lets you know whether it's the 16MB expansion or the 8MB memory card that can be accessed currently. This means you cannot access saved files on both memory cards at the same time, but at least you can access 16+8 = 24MB's worth of saved files via a single port without rebooting the system or physically replacing the cards. With 2 of these and 2 memory cards, you can have 48MB's worth of memory using only 2 memory card slots compared to the 16MBs you are limited to if you are only using the regular memory cards.

At $12.49, this is defiinitely a great value and a great alternative to a Sony brand memory card, which gives you half the amount of memory at double the price.

Disc Swap Tricks to get more memory  Jan 17, 2003 By Christopher Green
This comes with such an annoying bootloader that you have to use before each and every game. There are a few games (such as Super Bust-a-move) that this doesn't even work with. It's a hack and it makes you swap discs each and every time you load a game.

Spend the extra bucks and buy a real memory card.

Crap!  May 05, 2005 By Daniel
I buyed this item two weeks ago... I put many saves in it... Works very well! Works like a single memory card(don't need to swap, no CD is included anyway!!!)

But today my PS2 tell me that this 'memory card' is unformatted. Impossible to see my saves...

I choose 'Format It' and I see 'Format Failed'!!!

It's now impossible to save on it. And I lost all my saves! WOW!

(...)
DON'T BUY THAT ******!

NEVER WORKED  Aug 02, 2005 By Jason J. Dimarzio
My machine wouldnt recognize the card. Total waste of my money. I have the new slim PSTwo machine... I DO NOT recommend this to anyone. Do yourself a favor and just buy the regular memory cards.

It works fine....until the day you wake up to find that it has crashed on you, and all your stats and saves are down the toilet
