GameBoy Pocket > SongPro > Fiio E11 > Shure SE215LE 
It's not working quite right so I'm going to buy a GameBoy Color soon. I'm also having a hard time trying to install 12 year old software on a modern computer.

It's not working quite right so I'm going to buy a GameBoy Color soon. I'm also having a hard time trying to install 12 year old software on a modern computer.

Looks like a GameBoy Color.. correct me if I'm wrong.
Edit: ok so it was wrong..
ugh there's no way I can't buy a Songpro... have to go dig up the old gameboys.
Is there a maximum SD card capacity for these things?
The box says 512mb. Once I get my hands on a GBColor, I will let you know if you can run anything higher. I don't know if 512 is the limit right now or if that was the biggest you could buy in 2000/2001.
Also, SongPros only take wma's and mp3's. This is more of a fun experiment you can do for around $30 if you don't have a Gameboy. The SongPro cost me $11 shipped.
This picture shows a 1GB card in a Songpro:
I'm just doing this because the SongPro was a huge flop and no one really knows about them. It's pretty much guaranteed that you're not going to come across another person rocking out to music on a Gameboy + SongPro. 
I think my mind would explode if they came out with a version for the Gameboy!
Thanks, they are definitely my favorite looking IEM's by far. I think Shure did an even nicer job than with the limited edition SE535s.
I have too many gameboys and the silly useless peripherals like the camera and printer. I had no idea that there was a mp3 cart though. I'll have to get one of these even if it can only hold a few songs.
Thanks for enlightening me 
Oh, No wonder I didn't realize what it is, I never have a gameboy pocket before , I only have gameboy colors
Where did you get the Songpro?
Here is where I bought it from. The Songpro was new but the 32mb SD card was taken out. Still, it's pretty cheap.
Its a gameboy pocket apparently that is why the general outlook doesn't look like the gameboy color I remember , GBP as a DAP, this is very new isn't it
