Game Boy is my favorite system of all time. I've owned or played just about every console too. Sometimes I get hooked on a classic game and my PS3/PS4/Vita/iPad gets put on hold for a week until I beat it. The original black & white though. I'm not so big on the color and advance. I actually owned a large portion of AAA titles from the GBA gen and ended up selling them over the years to fund my other gaming wants.
I'm less then 10 titles shy of the entire North American release set. I will spend a good portion of my visit to Midwest Gaming Classic this Saturday hunting down orphaned boxes/manuals for my collection. Oh and also hunting down hilarious imported fakes. I have a collection of multis and fakes going strong too. Some of those are like art. Harry Potter with flying broomstick enemies. Sprite hacks of Mario Land 2 with fat Pikachu. That's just to name a few.
I would like to play them on a HDTV. HDMIBoy is too costly. Retron5 is a bit costly too. I settled on picking up a few of those Kong Feng GB Boy systems to use besides my two AGS-101 SP units. Then I discovered the magic of the Raspberry Pi 2. I'm in the process of making a emulation paradise with that so I can leave my games on the shelf. I'm a bit of a perfectionist though. I want to put all the games, cover art, info, etc on the unit before I start using it though.
If any of you are looking for import Game Boy titles, even some that are not language specific, check out
Japan Retro Direct. He sells lots of cheap Game Boy titles. I've started buying from him as I start to dabble into imports.
