Misc are there test ROMs for nDS?

[niomi]

I'm trying to test my DS lite battery life & uptime. When I was testing my GBA battery I ran the AGS aging ROM. I could run that out of slot 2, but I want to run the test a ROM from R4 specifically. I would also be interested in any other useful DS utility ROMs, if they are a thing. I am including some pictures just in case my specific hardware is relevant. (firmware is Ace3DS+_R4iLS_Wood_R4_1.62)

You'll want this: https://tcrf.net/Aging_Card_NTR. V6 is for the DS Lite.
