Might resort to that later.yeah, you can also "untrim" via 3dsexplorer, but iirc the card1to2 tool was a bit hit & miss, some work some don't....PS did you try doing what i showed in the SPI quick fix video, would save you having to try convert games to card2....if all else fails i would say stick to cia games for better compatibility
I use CTR_TOOL for trimming/untrimming.
