*Thinks this is the time and place to pimp the GP32*
How about getting a GP32 instead? The prices are similar, and there is now a full speed with sound pc engine emulator running on it (
http://gp32.emu.pl/gpengine/). This means that you never need to actually spend money on games if you don't want to.
Also, there is a working GBA emulator for it, its very very slow at the moment, but is being worked on.
Other advantages are the mp3 player, and divx player…and a nice neo geo pocket style clicky stick. What more could you want?
Have a look at some of the other games and emulators here

*will shut up about it now*
Back to the topic, am I the only one who disagrees with the idea of having to buy a headphone adaptor? So what if its cheap, and the system is smaller because of it. Will they sell the screen as a separate accessory next?
