Hi, I'm trying to run this on my flashcart, an R4i SDHC . YsMenu has been set up and working fine. But I can't seem to load past the DSi Menu- I pick a .dat (I have three on my root now which I'm sure is wrong but idk which one to use/keep: _BOOT_DS.dat, BOOT.NDS, BOOT_cyclodsi.nds. yeah i've been at this for a while) and when I pick TWiLight Menu+++ from the DSI menu I get an nds-bootstrap error. It just has the memory card icon and says error occured. It may be worth noting that it at first said nds-boostrap wasn't found, and then when I downloaded it from ahezard's github I started getting this error.
EDIT: I figured it out but it was mostly just me being dumb. I didn't know select is what booted you into the DS menu, so I kept thinking I had to launch Twilight Menu ++ from itself for some reason

Navigated to games too and it plays perfectly.
I hope acekard themes are reinstated in the near future, there are some really good themes for that thing.
