-screen size about the size of psp-bright enough to play, adjustable unless its too difficult
-all buttons
-cartridge deck (of course)
-memory card (for games like rayman 2, a lot of my games need it)
-expansion pack for DK64 (necessary?)
-speakers with headphone port
-rechargable battery
i want it shaped something like a nds (no flipping). the screen on top, buttons and speakers below. something like this

the circle with A is the analog. i think i'll put the Z button right behind it. the dots under the start button is the speaker. the cartridge deck, should it be behind controls, the screen, or mid-way?
also a question about N64: are there any games that require the L button? because most used R and Z instead of L.
