Compared to hardware development, I prefer to enjoy the joy brought by game development. I want to have a more relaxed development environment, where music can at least play midi (I like midi effects very much), mp3, wav. This requires large-capacity cartridges and audio decoding chips. It can be developed in C language, with a higher CPU clock speed, so that I can freely express my imagination when creating.
So I have always had this idea, to make the game platform I yearn for, and then develop games on it. I will feel very happy. As for making money, it's secondary.
I think at least a few game developers on the VGS forum share my thoughts. I would love to share the joy of making games at HS.
