Not that this is recommended, but I got tired of waiting for my Pi400 to arrive. I dusted off an old Pi3B (not even B+) and edited the config.txt to overclock to 1.35Ghz and video to 550, and the dang thing works! This was using a Kano Computer Kit Complete (2017).
It won't handle everything in the build - such as Akai Katana makes it craaaawwwwllll - but overall, the vast majority of games move right along.
Just thought I would share this little discovery.
V3 coming very soon - and I will have a proper Pi400 so I can screen cap and update you on all the changes/fixes/additions.
