Hi mates!
One friend of mine was using his classic 2DS and updated it accidentaly. His 2DS is now showing this error screen Booting up:
"An exception occurred
Proccesor: ARM11 (core 1)
Exception type: undefined Instruction
Current process: pm (0000000000000000)
R0 E0E01BF5 R1...
I may try the new ram site, and download more RAM to my Switch. Not sure if ddr3 is the right ram
for it tho. Edit- no it uses floppy Ram, just like @AncientBoi
