Brand new multi-tap for Playstation, PSone, & Playstation2(for Playstation 1 games only).

Use up to 4 controllers(5 controllers if also use second socket on Playstation itself) at once, from one joypad socket on your game console.
Also has a memory card socket for each of the 4 joypad sockets.

Play with or against your friends - ideal for racing, sports, shooting, fighting etc games.

Supports all joypad functions: analog sticks, vibration etc.
Also supports light-guns, steering wheel, & probably all other controllers.

By using 2 of these, you could have up to 8 people playing at once!

NOTES FOR USE WITH PLAYSTATION2:
It seems the memory card sockets can't be used when connected to a Playstation2, however you can still use both of the memory card sockets on the Playstation2 itself, so it's not important.
This will fit in both the original, & slim model PS2s.

The Playstation2 can't use an original Sony Playstation2 multitap for Playstation 1 games, it requires a Playstation/PSone multitap like this one.
Some multitaps are specially designed(I think Sony multitap for Slim PS2 are) so can be used for both Playstation2 & Playstation 1 games, but this isn't standard.

Controllers shown in photo are for illustrative purposes only, price is for multitap only.

Examples of Playstation1 games that apparently support multitap:
NBA Live (any year)
almost any soccer game (eg: the FIFA series)
Poy Poy
Bomberman World
Need For Speed 5
Circuit Breakers
Hot Shots Golf 2 & 3
Gauntlet: Dark Legacy
Running Wild
+ a lot more (especially sports games)
