Action Replay codes are hexadecimal cheat codes that are essentially on-the-fly ASM patches. They can easily be translated into ASM. Lots of AR codes have been documented for SM64DS, ranging from codes that have been made into SM64DSe patches, like Skip intro, Infinite health, Choose starting character etc. and there are also funny AR codes like moonjump, walk-through-walls and the ones that allow you to play as Signpost.

This thread is for sharing your Action Replay codes for SM64DS, from useless funny ones to ones useful in ROM hacking, either ones found online or codes you found yourself.

Always specify the ROM version your AR codes work with!

Here I have one. Found on a French-language site, so probably for the European version:

Yoshi won't lay eggs from eating enemies/shells/crates until (R) is pressed

6209B468 00000000 B209B468 00000000 10000677 0000FFFF D2000000 00000000

I haven't tested it in-game yet, to see if it really works on a 0022 European ROM and if it won't cause glitches when:
 • entering a swimming state (would normally cause Yoshi to auto-lay his egg);
 • collecting a power-up;
 • eating an actor that never turns into an egg, like the Baby Penguin, fire, Ukiki, Bob-Ombs...

It would definitely come in handy in ROM hacks to be able to choose whether or not to lay an egg.
