i'm interested in emulator development but idk where to start

i know c++ and a bit of assembly

my goal is a psx emu, (yes i know its a big one and it'll take a long time to accomplish),, and probably not the best idea either..

but my question is where do i find resources, tutorials, and stuff like that cuz i barely found anything on the web and yt

thanks to anyone who comments with helpful advice ^_^
