similar question, I designed a working gameboy game for the jam. In my submission I included a free-to-use emulator (.exe) and a .gb file (the rom of my game). Is this acceptable?
EDIT: Turns out it isn't hard to make a web build. Made a web build and added it to the itch.io page for the game. Plays in browser now. Web version files will also be added to the source files as well.
