I have a Trimui Brick and a RG Cube XX.
On the Cube, the same Roms are working, on the Brick i will just get send back after a short black screen.
I tried to start the roms with a complete new install and only 4 roms on the sd card. I also tried the core reset and the drastic restore configuration.
Now that i also updated my Cube to Jacaranda, I can confirm that all DS Roms that fail on the Brick, are loading and playing just fine on the Cube.
