I have a DS Lite (and O3DS, although just for testing what happens there) with this cart https://sanrax.github.io/flashcart-guides/cart-guides/r4i-sdhc/, more specifically the r4isdhc.com 2015 model. I setup the card with r4isdhc.com v4.3b kernel, I put gbar3-frontend.nds in _gba folder and GBARunner3.nds in /. On both consoles, when I launch gbar3-frontend.nds from the menu, kernel is stuck at its Loading… screen before any output from the launcher happens. v0.9.0-fcnet3 starts GBA ROMs normally.
