Product.Description

This is a hand-made portable Super Nintendo, with ALL the games built in! It uses a standard mini-SNES and PSOne LCD screen (modded with LED backlights) with an extra circuit that lets you load games off of a SD card. The case is made out of laser cut acrylic glued together to form a box.

It is portable since it can use an external battery pack for power and contains a switching regulator for extra efficiency. The power light glows green in normal operation but turns red when the battery is low. The built in controls can be used, or standard gamepads can be plugged in for 2 player games. This automatically overrides the built in gamepad. A new TV encoder chip provides S-Video out and the LCD screen is modded to use RGB video directly from the SNES for the maximum video quality possible.

A custom made circuit board contains 4MB of SRAM and a flash ROM for the menu program. When the snes is in 'menu' mode it uses this built in program to display a list of games from the SD card. When you select a game it loads it to the SRAM using DMA, so it is very fast. After loading a game it can be reset into 'game' mode where it plays the game from SRAM just as if it were a real cartridge. Save RAM is also supported and can be written back to the SD card to save your progress. Both HIROM and LOROM games are supported, and proper save RAM size is implemented for copy protected games like Donkey Kong Country or Bust-A-Move. The only missing feature is custom chip support, so games like Starfox or Mario Kart will not work, you will need a real cartridge for these.

This thing took forever to build and was very expensive, so it is NOT FOR SALE as a product. You can make your own, however, if you design and assemble all the circuits yourself! Also note that my friend runs this web site so I am only a guest here, he can't answer any questions about it.

Made by Jonathan Scobbie 2006-2007.

	First Board This circuit board has the power supply, battery monitor, TV encoder and controller circuit on it.
	Second Board This board has the flash ROM, 4MB of SRAM and save RAM on it. A CPLD does everything and can access the RAM directly since it sits between it and the SNES.
	First board attached to SNES Red wires tap into the RGB video and the controller port as well as the reset signal (the CIC chip is bypassed, but still there to keep the cartridge happy).
	Final construction All the components together before closing the back cover. You can see how the second board is connected to the cartridge port and the SD card.
	Running Here it is running. It is hard to see, but it says it has 656 games!
