Hmm, I really thought I installed agbcc just as the document says, so it must be something I'm missing here. Although that guide was for pokefirered, it should still be the same process for FRLG+ right?
I tried again from the start but I still get the same error message about "/bin/bash: arm-none-eabi-cpp: command not found". Here are all my steps:
In the install file for FRLG+ (
https://github.com/Deokishisu/FRLG-Plus/blob/master/INSTALL.md), there is a prerequisites section about installing devkitpro and some commands, is this necessary even when using WSL1?
Thanks for your help.
