What happens when you are on the black screen, turning off Hardware Renderer? (it will be very slow but you should be able to see a picture instead of a black screen).

#8

the loading bar loads but after that is black screen. I tried turning off Hardware Renderer still black

Ok, I think your rom is corrupted in some way. Redump it using the guides below, first link for cartridges and second if MH4U is installed on your 3DS / 2DS:


Make sure you have enough free space on your SD card before you dump, preferably 4GB free.
