How can I test my homebrew Nintendo Entertainment System software on real hardware?

A few years ago, I implemented an NES game as a class project, written in 6502 assembly. I only ever ran it on an NES emulator, but I would like to see it run on the real hardware. Is there any development board to do this? I understand it is somewhat tricky, with mapper chips and such, but I am开发者_开发技巧 willing to limit to just a common mapper (say MMC3).

I would check out RetroZone, especially the page with Developer Tools for the NES and SNES. They have a device that you can install into an NES to flash carts (like this one) or a cart that will read ROMs off of a CF card.
