So I recently pulled out my DS Lite from my drawer and wanted to play on my R4. It is an R4 SDHC Gold Pro 2018 version. When I started up my DS, it locked up on the health and safety screen. I thought my DS did not work because of the long time of no use, but it does work. I inserted Mario 64 into it and worked perfectly no lock ups. I also tried Bowser's inside story and it worked. I updated the r4 firmware to v4.0 and still gives the same error. Is there a fix to this?
