Nintendo controller on a PS2

I figured if anyone has heard of this, you guys would. I'm thinking about getting ( or making ) something that will let me play a PS2 with a Nintendo Controller. ( ultimately I want to use the power glove for Gran Turismo ) Has anyone heard of anyone doing this? How hard ( if possible ) would it be to make? Anyone with any thoughts on this?

why would you want to do that in the first place? the PS2 has 6 more buttons than the NES so you wouldn't be able to control it.

again, because I want to use the Power Glove for Gran Tursimo. You're just using the gas and the brake anyway.

then it would be probable, nay possible to do it, though you'd have to sacrifice a nes controller and a ps2 controller.

ok essentially what you would have to do is swap out the NES Power Glove guts with the PS2 controller guts

and essentially it would just be a limited hardware functionality and that won't be too hard (minor hardware hacks)

Unless you don't want to ruint the functionality of the power glove to the NES, then you wold have a very complicated programming task in front of you,

See the format of the NES controller ad the PS2 controller are VERY different, the NES boils down to the up/down philosophy and the PS2 does something more complicated

Syncing an up/Down with a PS2 format would be the hard part

But in racing games you don't need up and down.

Madcatz made this a few years ago:

Read through Ben's book I am talking about the electrical signal displaying whether the switch is up or down

as in every button on the NES is on up until the switch is engaged and the rresitor tranfers the current to the "up" position

Well, that's basically how the PS2 controller works as well. It all boils down to what encoder chip the controller uses though. I know that the NES uses a 4021 8-bit shift register, which basically converts parallel data (buttons either on/off) into serial. Gamesx.com has more information if you want to read about it.

Best way to do it would be to build an interface circuit, so you can plug in any controller & have it work.
Either one to decode the NES & one to encode the PSX signal, or use a programmable microcontroller (eg, PIC) to do the lot.

There are circuit schematics for making a PSX controller using off-the-shelf chips (linked off GamesX I think?) and if you look up the NES chip (4021?) you can find out how to build a decoder circuit for it too.

Oh, and I believe the PS2 uses analog buttons, though I don't think there's many games that actually use them that way. PSX controllers work just fine.

That's exactly what I was thinking. I really don't want to take apart the Power Glove to do it, so I was thinking of some type of go between for the connection. Thanks for all the info everyone.
