GameShark/Action Reply on Roms

I've looked up how to do this but all I've goten is pc solutions. I haven't found a way to do it on the wii. Is there a way? I'm familiar with the actual hardware since i've owned them in the past. You PnP, select the game and it loads with the hack. Have any of you tried this on the Roms?

What ROMs are you talking about? Which console are you referring to to and what emulator are you trying to use?

the roms would be pokemon and yugioh for the vbagx on the wii.

Well, I haven't actually used any emulators on the Wii, but I believe that for most that support cheats, you have to download a cheat database from somewhere and put it in the SD card, then configure within the emulator which cheats you want enabled. Hopefully someone with experience in this area can help.
