Gameboy Advance was great
Incredible handheld with lots of great games. Lots of fabulous NES/SNES ports and lots of fabulous originals too. Plus backwards compatibility with the Gameboy and Gameboy Color.
The only problem with the system was that the original model had a poor screen. The SP model fixed this.
It was also among the last old-fashioned systems, that simply played games and didn't do much in the way of multimedia. They did have "GBA Video" but that didn't make much of an impression.
Glad to see GBA games coming to the Wii U virtual console.
Have you played Atari today?
