Tonight I discovered that I can emulate ColecoVision perfectly on my Wii, and I experienced the joy replaying some of my favorite childhood games that I haven't seen or heard the music from in 20 years. =D
First I installed the Homebrew Channel on my Wii's SD card, then using the Homebrew Browser I downloaded WiiColEm, and from there I just popped the SD card in my computer and loaded ColecoVision ROMs on it. I also have Atari 2600, NES, and Genesis emulators on the Wii that all work great too. =)
