For those of you who are interested in "how to make a SNES game", I've just published a long article about making my SNES game Yo-Yo Shuriken.

It starts with the various steps I went through to design and program the game. Then, it details how we manufactured new cartridges (with box and manual) for a console whose commercial support ceased more than 20 years ago! (spoiler: all cartridges and boxes and hand-assembled for each order!)
