Hi everyone, I’d really appreciate it if anyone can help figure out this issue. I’ve been playing Pokémon HeartGold on my NDSL with an R4 Wood flashcard (the one shown in the picture). When I set up the Wi-Fi network on the game menu and press B to exit, the game should normally soft-reset and go back to the main menu. But instead, the screen stays white for 1–2 seconds, then turns completely black. The game background music keeps playing, but all buttons stop working — even the hard reset combo L+R+A+B+X+Y does nothing. The only fix is fully rebooting the console, then the game works fine again. If I go into Wi-Fi settings and exit again, the problem happens every single time. I also own a 3DS, so I did a cross test: I put the same R4 card into my 3DS and launched HeartGold. The exact same black-screen-with-sound crash happens after exiting Wi-Fi settings. This proves the problem is not with the console itself, but the flashcard/kernel. I also tested another 4th-gen Pokémon game, Pokémon Diamond. When entering and exiting Wi-Fi settings on Diamond, it soft-resets perfectly with no issues at all. I thought it might be a corrupted ROM, so I re-downloaded the clean original ROM and applied the latest official Chinese patch — the problem still exists. Then I installed the dual boot kernel setup from the NDS community: primary kernel is Wood R4, secondary is AKMenu-Next. • Booting HeartGold with the Wood R4 kernel: exiting Wi-Fi still causes black screen, music playing, no button response. • Booting with the AKMenu-Next kernel: exiting Wi-Fi works perfectly, normal soft reset, no crash at all. After all these comparison tests, it seems like the Wood kernel has compatibility issues with Pokémon HeartGold, or there might be some hidden setting I need to tweak. Could any experienced players please explain what’s causing this and how to fix it? Thanks a lot in advance! 🙏🙏

BlocksDS-Nix provides an easy-to-use, comprehensive Nix package for Nintendo DS development with BlocksDS.

I recently got into using Nix/NixOS for software development, and I have really come to love it! A common side-effect of converting to Nix is that you develop an insatiable desire to port everything to it

I am currently using this utility in my own homebrew projects, and it seems to be working very well!

You can find more information, along with some examples, on its GitHub page.

How to use

As a prerequisite, you need to have Nix installed on your system, and have flakes enabled.

Use the "simple example" in my repository (https://github.com/pgattic/blocksds-nix/tree/master/examples/simple) as a starting point. You only really need to copy flake.nix, Makefile and source/main.c.

Type nix build . to build the example Nintendo DS rom! It'll be placed in result/simple-example.nds. If you want to do interactive development, type nix develop . to enter the devShell, and then type make to build it (should be much faster for quick iterating). In this case, the rom will just be put in your current folder, not in result/.

As mentioned above, check out this project's GitHub repository for more complete information and usage examples.
