Hey /g/, since /prog/ is dead and you are my last bastion before I head to /r/programming I thought I'd ask you a question. TL;DR is at the bottom.

I recently bought a Raspberry Pi Model 1B from my friend, and have been playing around with it on its emulation aspect. I've been playing around with SNES Emulators and I find that they run so terribly on the Pi, even with an overclock. So, I thought of this:

Program an emulator specifically for the Raspberry Pi. Write it up in C/C++, compile and optimize the resulting ARM assembly. What I am wondering, however, is if the resulting program would be fast enough, given that one would also have to emulate the many chips included into the cartridge rom files.

TL;DR I want to make an optimized emulator for the SNES, would it be faster than say SNES9X? Is there anyone on /g/ with experience programming emulators? Am I just wasting my time?

It's the hardware,not the programming.You just wont be able to run it on a pi,no matter what optimization you do

Well, considering that I got my Model B running at 800Mhz and that the SNES ran at approximately 4MHz the emulation couldn't possibly take up more than 600MHz, right?

I mean, I never programmed an emulator before but basically it is just reverse engineering / finding a doc on the ISA and use that instruction as how a modern computer would, right?

or just buy the raspberry pi 2 model b for $50 and be happy

I was looking into that but I was worried that the SNES would also have shit emulation on that too... Not to mention that Pi2 doesn't have the composite video out.

I'm a guy that tries to make the most of the things he has.

the pi2 is powerful enough to emulate snes smoothly

get on with the times and get hdmi

or just get a hdmi>composite video adapter, I am sure some chinese guy is selling 1 on ebay

The problem isn't HDMI, it's viewing in sweet 4:3 NTSC on a beautiful Cathode Ray Tube Television.

I'd imagine that using HDMI I'd have to finagle some sort of contraption to make it work.

And if I turn down the graphics on Batman Arkham Knight so hard they actually compare with a SNES, I might get 5FPS on an i7.

what about some sort of usb -> composite video contraption?

Custom Maid 3D2. It's alright. Ask around on >>>/vg/hgg

>>52225118
Nevermind I'm retarded. Pi2 does have RCA but I'm still worried about emulation...

Nope. Straight up porn game.
I know, I wish it wasn't too. I wish my waifu got a 3D game for once.

Bought it off a friend for 20 bucks with keyboard and shit... probably should have kept the money seeing the Pi 2 was out but whatever.

attach a motor controller board to it, put 4 individual motors with wheels on it, a wifi dongle and a webcam and you're all set for a remote controllable 4wd spy car

Bullshit, I used to run SNES and even N64 emulators on an old junker PC with a 466 MHz Celeron and 256 MB of RAM.

remember how quick zsnes was back in the day? that was done in (mostly) x86 assembly, and had lots of performance hacks, it ran well on machines far slower than the pi

The pi2 has a combo video/audio port and hdmi. Just buy a cable.

As if you would actually post this on /prog/ and receive anything other than a big, fat "you're a nigger", if even that.
