There are a handful of 3DS games I want to play. I was able to get MH4U and SMT: Strange Journey Redux working through Retroarch using a Citra 2018 core. When I tried both SMT:IV games, I got a black screen briefly and then Retroarch closes. I am curious in how to troubleshoot this. If it helps, when I select the previous two games, it allows me to choose one of the 3DS cores. When I select either of the latter two, I don't get that option, just black screen and everything closing. Thanks in advance for any helpful input.
