Dear Ben,
I have an idea that I hope will catch your eye. My idea is to build a portable, hand-held system that can read SD cards with emulators and ROMS on it. I believe this idea is good because a younger generation is interested in the 8-bit community and they want to play the games. But because it is a younger community they do not have the games or systems to play them. With this device you can put emulators on an SD card and ROMS and play ATARI, NES, SNES, and other systems without a cartridge. This design is good because you could use an old Gameboy case and add buttons and it would not be too hard.
Thanks Ben for considering this,
Nick Streiff
