So, I don't know if this is the best place to post, but I am hoping that it is.
I am planning on building a custom board, similar to an Arduino, but I think it will be a MIPS chip. I am trying to more or less build a Nintendo 64 from scratch with a few extra features such as being able to download games via WiFi, HDMI output and and emulators for other retro systems: NES, SNES, GameBoy, etc. I would like to see if anyone could point me in the right direction in order for me to learn a bit about building my own board. I have some basic circuitry knowledge and I believe that I understand what components I will need: Power Supply, Ram, Rom, CPU, HDMI Encoder?
Any help is greatly appreciated.
If all goes as planned, I will have the OS and Emulator source code on GitHub, Schematics and a Detailed Build on Instructables, and a demo video.
I just dost know where to start.
