64 bit support #174

Closed ustix closed 1 year ago

ustix commented 2 years ago

Dear Exophase!

Are you planning to make a 64bit version of this emulator? I have built the retropie on a dietpi bullseye 64 bit with an fbcp-ili9341 screen and i think your emulator is the best one because the others aren't even able to make fast forward fast (that's how I measure their usefulness), so I would be really excited to have your work ready on my experimental setup!

Thanks in advance!

I don't think Exophase follows this fork.

@hizzlekizzle can you help in the topic? I have seen your name somewhere, maybe at RetroPie reddit?

hizzlekizzle commented 2 years ago

Adding 64-bit support is far out of my expertise, and I can't speak for everyone, but I think the general consensus is that 64-capable devices should be able to run more accurate and compatible emulators, such as mGBA, which makes the cost in labor of adding 64-bit support to gpSP outweigh the benefits.

I think you are right and I shouldn't have to force raspberry pi zero 2 running 64 bit system with retropie, because it doesn't affect its performance in a good way and I am also getting compatibility issues with emulators when their performance matters, like mgba or vba-next is very bad compared to gpsp, but maybe they are not that bad with a pi4 for example (which i don't have, so can't tell really, but i have a radxa zero which is more powerful, so maybe i will try that.). Thanks for your detailed answer!

There is an ARM64 Dynarec available for this emulator thanks to the work by @davidgfnet, but the core needs to be built with this enabled. Check out the relevant files in the ARM folder in the repo for more details.

There's 64 bit support. You can build the emulator for any 64 bit platforms. There's dynarec support for arm64, x86-64 and even mips64!
