How do you prefer to play GB/GBC/GBA games?

PSP 3000. Seriously, the emulators for PSP are great, savestates, screenshots and the bigger screen make playing games on the original hardware a chore.

But if I'm gonna go with the original hardware, I like the GBA SP 2.0 best of all, closely followed by GB Player. The Super GameBoy is nice in a pinch, but the GB Player is almost always the better option unless you're playing one of the several dozen games that specifically use the Super GameBoy to enhance the game.

I use the GBA SP 2 or the Gameboy Player on a Gamecube.

If I actually have the game, Gameboy Pocket for anything pre-Color, standard model Color for anything during that era. If I don't actually own the game, VBA Wii version (via the Homebrew Channel).
