Hello, yesterday at the Retropolis Valencia party, I introduced RVMPlayer.
Rvmplayer allows you to embed an Amstrad CPC or ZX Spectrum emulator on the web with just a few lines of code and auto-load a game.
It is perfect for the websites of new homebrew developments.
It's in an early stage, but you can see how to do it here:

You can also see the first game that has integrated it on itch.io here:

Best regards
