This is annoying, it happens to me too!! There is nothing you can do besides turn it off. Sorry i couldn't be more helpful.
no in pokemon gold
Redownload the ROM, as it may be a bad one.
If that is the only game that freezes, then the rom must be faulty. You may as well download another rom and put it into your r4. If it happens with all your games, then the software in your r4 might be faulty.
now
k first its heart gold not "shiny gold" and all u need is the ds
Get Desume
It is not an official version. It is a ROM hack of FireRed made to be like Pokemon Gold.
You should get the visual gameboy advance application, once opened, select "File", then "open gameboy" and choose the shiny gold version rom, NOW HOW DO I DOWNLOAD THIS ROM FOR FREE !? By the way: you'r welcome.
To play it, all you have to do is on the emulator, go to file > open > choose your ROM (Gold) and start playing. If you have VBA, you can choose your controls from Options> Joypad > Configure > 1.
go to coolroms.com in search type in pokemon then look for heart and gold then download it free
actually in 2010 next year Pokemon heart gold and soul silver will come out im not sure when, but it will come out on Sep. 12 in japan if you want a ROM
Why are you even playing heart gold? if you are then it must be the illegal ROM or something.
