Looking for Actions Replay Codes for Pokemon Alpha Sapphire that actually work

So I am replaying Alpha Sapphire atm and i want to speed up a little by getting my hands on some rare candies. I went and looked for cheats but nothing i found worked for me. Why is that? Are the codes just outdated or am i doing something wrong?

It’s a lot safer and easier to just use PKHeX. There’s dozens of guides on youtube if you don’t know how to use it.
