There is a problem with the link for the romhack and for the cheat code (in the rules section). The link to the hack doesnt work, and Project64 doesnt let me add the cheat code. I searched for the hack but i couldnt find it, can someone pls send me a link to the romhack?

What version of PJ64 are you using? If you are using the correct PJ64 version (v1.6.x), you can enter the codes. This thread might help, which explains how to enter codes into PJ64 v1.6.x: https://www.speedrun.com/sm64/thread/c1dhu

Just make sure to enter in the codes for 1000 Unique Coins instead of the Nonstop codes. The thread also has a link to the PJ64 v1.6.x download with instructions if you aren't already using it.

I am using Project64 1.6, and if I Paste the code in the Cheats Section, PJ64 doesnt let me add the cheat code.

But also, the code is in one line so it looks like this: 8124B2A8 2400 8124B2B0 2400 8124B2B4 2400 8124B2B8 2400 8024BEB9 006B 8124BEC8 2400 8124BED0 2400 8024BF3D 0000 812CB1C8 3C01 812CB1CA 8016 812CB1CC 3421 812CB1CE AA94 812CB1D0 3C0A 812CB1D2 8033 812E3DC0 2400

and not like this: 8124B2A8 2400 8124B2B0 2400 8124B2B4 2400 8124B2B8 2400 8024BEB9 006B 8124BEC8 2400 8124BED0 2400 8024BF3D 0000 812CB1C8 3C01 812CB1CA 8016 812CB1CC 3421 812CB1CE AA94 812CB1D0 3C0A 812CB1D2 8033 812E3DC0 2400

but i also tried to paste that code in the Cheats Section, but that doesnt work either.

So I just tested it and I was able to add the codes to PJ64 and it accepted them (on the US version), however, it is just resetting the game after file selection. So I think those codes may be incorrect (I tried the ones you pasted and the ones in the rules tab of the 1000 Unique Coins page).

Your best bet is to join the ROM Hacks discord and ask your question there. I'm sure they have a working link to the ROM Hack/codes, or at least someone who can direct you to it. Here is the discord: https://discord.com/invite/BYrpMBG

I tryed updating my PJ64, and now I can finally add the code and run the category, ty! It also fixed a weird glitch at the beginning that lost me a second.
