Hardware How do I build a 64-bit Homebrew console?

[Calegxm999]

Can anyone help me make a 64-bit homebrew console?
I have been researching for a long time, and there's not a scrap of help!

Can you be more specific? What exactly would you do with it? Do you want to program your own 64-bit games? Is there some reason you need 64 bits for that?

If you want to run an N64 emulator, then you don't necessarily need a 64-bit system to do that.

You have previously stated that you are bad at complex coding. Are you expecting a "64-bit hombrew console" to somehow be easier!?

Yeah nobody really sets about to make a console with a number of bits.
They might want a specific family of CPU to power it but anybody concerned with number of bits in their "homebrew" device is either a time traveller from the early 90s or is building a basic data gathering tool and has to choose between 8 and 16 bits for their microcontroller.

The family* of CPU has a far bigger set of consequences than the number of bits either available for general/notable amounts of instructions in the CPU registers, or a marketing stunt where something is 64 bits inside the device and thus 64 bits gets picked to designate it because it sounds cool.

*There are many but mostly people are concerned with a few of them. ARM is presently mega popular and has a bunch of stuff available for later revisions of it, X86 (though I suppose if you are set on 64 bits then AMD64 or X64) is what the PC uses so you have that available to you, I don't think there are many 64 bit powerpc, MIPS or anything else in that world.

Single board computers might be worth looking at (think raspberry pi, beagleboard and
While intel will have some X86, or indeed, stuff a "console" might also be able to use a small board designed for media computers https://all3dp.com/1/single-board-computer-raspberry-pi-alternative/ https://www.mouser.co.uk/Embedded-Solutions/Computing/Single-Board-Computers/_/N-aez3t and so forth.

this is an 8bit computer (game console) im working on, its based on a 6502 and atmega 644/8515,

not 64bit or hi res but even coding something like this with only asm and C and you have to do everything, video, sound, garbage collecting, io, subroutines, everything has to be accounted
and timing is critical, and this is 8bits + bank-switching, i need to add tri-stating for the 6502 so the avr can do dma (lets see who's know their chips to figure this out)


you just don't choose a random bit width, when it comes to computers, you chose based on what you want to accomplish, but be very careful to set limits, or else you'll have a runaway train... you end up adding so much your goal isn't clear anymore

need to be more clear, do you want to build a computer from scratch or from pre-assembled parts (build a desktop, raspi box)

1. Get PC
2. Install Lakka
3. Done?
