Homebrew How do I change a DS (Download) game to have DSi headers?

title says it all, here's a small conversation that explains what I'm asking:

Sorry for late reply.

Write the following at 0x180 in the .nds file, with the highlighted area from the below photo.

At 0x230 is the TID from 0xC, but it's letters are reversed. For example, "CSXE" at 0xC, "EXSC" at 0x230.
So put in the TID (from 0xC) at 0x230, but in reverse.

Aha, thank you!
Sorry if I bothered you on the GBAtemp Discord

Unfortunatly, didn't work. I must've done something wrong, it never comes up on the DSi menu.

You mean it appears there, but the icon doesn't?

No, it just never appears because of some invalid values.
