I recently followed this guide to install arm9loaderhax https://github.com/Plailect/Guide/wiki/Get-Started. Everything worked out for 3ds games. I then put in my old DS blue card I got when I purchased an MT-Card back in early 2014. My 3DS shows the cartridge is loaded but when I click on the game to load it just goes to a black screen and nothing else happens forcing me to hold down the power button to turn the 3DS. Does anyone know what is happening to make it incompatible with my DS blue card and is there a way to fix it?
