1. I apologize, as I haven't really been in the homebrew gameboy loop since the the gameboy color. How is this any different from just using a cart player that reads off an sd card which can then be plugged into the computer for dragging and dropping of files? Is there something more grand here that I'm missing?

2. Well, among other things, making a direct cart interface will usually allow you to "dump" (copy) commercial carts, since the interfaces are usually designed to read as well as write.

Of course, I can't speak for this guy's homebrew device, but I have seen a number of the ones you can buy in the shadier corners of the Internet ;-)

3. @ 1 This interface could be used to transfer rom files from commercial GB cartridges

4. I realize theres educational fun in making electronic toys, but an easier solution for the would-be programmer is a used psp for $130 plus a 1gb pro duo card. Psp emulates gameboy at 100% although it doesnt have the nostalgic feel i guess.

5. in the pictures he shows his new board with the atmel uC with on-chip usb. he also shows what i think is the LPC board from sparkfun with the cart connector on it. which is he using?

he also suggests that there is a xilinx fpga on the cart? is this even possible given how old that hardware is?

6. The PSP doesn't re-create the gameboy sound effectively. Sadly, no emulator does. Its passable for video games, but the purpose of this is to write music on the original gray brick gameboy, which has a unique, bassy sound.
