[mgba] adding codes to games :-?

[AWESOMEGAMER]

I have tried adding codes to games and they did not work for weeks
HM more fronds of mineral town and HM gb

and they both just did not work
I also have mgba on my pc and I have added codes on there. I just thought I added the code in wrong on the n3ds or something but they still did not work.
On the pc I have the first one activated *HM MFoMT*because it would not let me pick Action Replay codes . There was nothing picked for HH Gb

I had gamyob but the cheats were greyed out and there was a(n) link but I could not click the download button to get the cheats for GB and GBC. I tried in FF (FF blocks the lnk) and Opera (opera just brings up a page with the header on it

I can add the codes they just will not work noting happens at all.

Thank You
Happy Hacking

I don't know much about the GBA options on the 3ds. If such things are troublesome though then there are options to hardpatch cheats into games

Even if you run that once and copy the resulting save back to the stock ROM you might be able to do what you want.
