I built some homebrew games for the PlayStation Portable circa 2004, in the middle of high school. I had some C and C++ knowledge, but barely knew what I was doing. Setting up the toolchain for building PSP homebrew on Windows XP involved a cygwin instance and all sorts of bizarre compiler and library packages that made almost zero sense to me at the time, and I had pretty much no Unix experience. I remember if I ever got linker errors, I'd just back up my source code (copy the whole dir to "game_backup_20040102" etc), delete everything, and re-do the entire installation from scratch, because I had no idea what a linker was or what the errors meant.

It's wild to me that I actually built and shipped two decent little games with that setup, lol. I put them on Itch a couple years ago: https://coldpie.itch.io/
