How can I replace an R4 flashcart menu with another?

[JuanMena]

I'm not asking how to load YSMenu or other loaders with my R4.

I'm asking if anyone knows how to "autolaunch" TTDS.nds in my R4, so it becomes the main kernel instead of the R4 kernel.

The card in question is an R4i-sdhc from 2012 and the latest working kernel for my flashcard is 1.85b.

I honestly don't remember how I got TTDS.nds in my R4 and I'm wanting that to be my default kernel for reasons.

Here's what I'm wanting to do:

Rename "TTDS.nds" to "R4.dat" and put it on the SD root.
