Console To PC Controller Adapters - Smart Joy or build?

[IMustBeEmo]

I would like to build some sort of adapter to plug in SNES and N64 controllers to my PC like the ones here but there's a problem. Those use parallel ports, which are now becoming outdated. Is there any way to build something like that for USB?

I noticed on Lik-Sang.com the super SmartJoy adapter and SNES controller extension cable and I also saw an N64 extension on another site, I don't remember where but I have it bookmarked somewhere. Do the Smart Joys work well with multiple SNES/N64 controllers and extensions? It seems to me with all that wiring there would be lag. If there is lag I would rather build something out of the female ends of the extension cables to create an adapter for USB. Also the SmartJoy seems kind of large and I would like to conserve space for traveling (Gradius III on a 5 hour airplane trip YES!!!)

IMustBeEmo, my man, i have no knowledge of adaptoids but the parallel one on an emulator with a current gen PC should do the trick just fine.

Yes I'm sure a parallel port would work fine, but I will be getting a new computer soon and I highly doubt it will have a parallel port. Of all the PCs and laptops I've seen at Best Buy, none of them had one. I am building, but I'm sure it will be all the same, especially in a couple years. I don't want my adapters to become outdated. But then again, it is ghetto gaming

So does anyone know about Smart Joys or know how to make your own SmartJoy type of thing? Could the conversion kits on RetroZone be used to make an adapter or are they strictly for controller conversions? I don't want to render my SNES controllers useless with my real SNES.
