Heh. I can just imagine a 486 DX4 running inside a cart. That would be funny, and something I'd be willing to assemble the hardware on(assuming my teacher gets the board etcher this year like he said he would). I am a computer junkie. I admit it. With a 486 inside, you could probably run Linux on the NES(I'm more familiar with Windows 3.x, Windows 9X and DOS shell myself). There are Linux OSs for GBA on Flash Carts, even. I am already planing my Famicom A and X, but they just have Japanese game support and Japanese Game support/FDS respectively, and I haven't made them yet. Tell me how the x86 NES goes, I will watch(and possibly participate) with great interest. ^^
Here's a slightly more realistic(possibly) idea for this time, though. I was looking through pages when I saw that there was a way to use NES controllers on an Atari. That got me thinking--why can someone make an Atari 2600(maybe even Intellivision or Oddessy?) emu/adapter for the NES? Put it in the cart and have the cart plug into the NES! Plus with a cart, you can have some of the Atari's actual circuitry for the functions, and then have the rest emulated by the NES. The Atari 2600 can be made fully operational at a size of 4 inches X 4 inches by cutting the board, and re-attaching some components. Here's a site with all the data:
They specialize in handhelds. They've made an Atari 2600 handheld, an SNES handheld and a PS One handheld. The people on the forum have nade NES handhelds, PSX handhelds, N64 handhelds, and are doing Dreamcast handhelds. These guys know a lot about hardware. ^^
Is there any practicality to the idea of an Atari 2600 cart emu/adapter?
What?! A Flaming Bowling Ball just hit my CAR!
