Pooptendo

This is Pooptendo, a Nintendo Entertainment System but stuffed inside with horse manure (emulator). Games may or may not work when you plug them into this Pooptendo.

Pooptendo is mostly complete i think, most games i've tried work with few issues.
you can try it online :)

Features

Pooptendo aims for accuracy but also makes some sacrifices for speed; i want most well known (and the fun) games to work, and the final boss is the froggy game Battle-Toads >:D (it runs! but it is a bit broken)

If your computer is new enough, most games should run at full speed, but stuttering does occur sometimes; if that happens, turn off frame-skip.

The CPU is cycle accurate, but there might be a few timing bugs lying around.
The PPU is emulated to the pixel level, though i sometimes make small sacrifices for speed, and there are still some missing features.
If issues show up though, (or if i manage to make it fast enough), i'll do my best to make it as accurate as i can :)

Functionality

POOPTENDO STATUS :: horse manure is clearing out

Pooptendo is written in JS atm, however I had plans to remake it in C. (This probably won't happen, I might start a new emulator in a language like C++)

how to use

Click Choose Fileto insert a ROM.

Fullscreen toggles fullscreen,
Frameskip toggles frameskip.

-- nes joypad
D-PAD   - ARROW KEYS / WASD
B       - X / L
A       - Z / K
START   - ENTER
SELECT  - SHIFT

-- emulator shortcuts
RESET   - R
PAUSE   - P

These are the default keybinds, they cannot be changed atm soz lol :3

compatibility

- cpu           (%95) 
- ppu           (%90)
- cartridge     (%25)
- apu           (%80)
- joypad        (%90)
- extra stuff   (%0)

Current mappers supported:

  • NROM
  • MMC1
  • MMC2
  • MMC3 (WIP)
  • UxROM
  • AxROM

importing

if you want to import Pooptendo to your site or something, first of all pls credit me :3, second of all:

import NES from './core/nes.js'; // Pooptendo is modular

var nes = new NES();
nes.attachCanvas(canvas);
nes.loadRomBuff(romBuff); // A Uint8Array buffer with the ROM data
nes.start();

By default, Pooptendo's default settings are:

  • NTSC
  • Joypad Enabled
  • Frameskip Enabled

Refer to nes.js in the core to figure out how to set it up to your liking :3

goodbye

having more experience after my Game Boy emulator, this emulator is a little more refined and the codebase is cleaner. i probably won't update it much anymore, but overall it was very fun :)

thanks for checking out Pooptendo !
