Emulation Classic NES Patches?

[rhfb]

Trying to get Zelda II to work, and I get the Game Pak Error message. I tried to find a patch for it and nothing. Should I just use a NES emulator to play it or is there a patch out there somewhere I just couldn't find(And yes, I checked the sticky).

I have some patches kicking around here somewhere that may work but really there is no reason to not use an emulator (better scaling, more features etc), here is a quick and dirty intro to NES emualation on the GBA and DS:
