Overview

Avocado is currently in an infant state of maturity and only a few dozens of games are verified to work in-game or load up something. For more mature emulators, PCSX-Reloaded is the best choice if you want to play 3D games at higher resolutions. If you encounter glitches or you're emulating a 2D game, use Mednafen instead.

For now, only the lead programmer works on it, but check the branches page to see more recent activity.

Despite this emulator being in early development, some 3D games can run.

Currently audio is hard synced to NTSC (60Hz) (running PAL games will make audio stutter), and MDEC (black screen instead of movies). The timer implementation does not function properly (games fail to boot or run at the wrong speed).

Features

Note: This is still WIP. You can check the changelog notes at the relevant GitHub repo's front page.

Graphics:

  • Hardware (OpenGL) rendering

Audio:

  • SPU implementation (Partial. Samples interpolation - less harsh sounds; pitch modulation - used by few games.)
  • XA-ADPCM (streaming audio) and Red Book audio support (Good but not yet complete)

Disc reading/File formats/Storage:

  • Memory card support
  • .chd file support
  • Refactored CDROM reading and cue parsing subsystems

Controls/Configs:

  • Support for digital controller, DualShock (without vibrations) and mouse (Two controllers are supported (no multitap for now).)

Running

Avocado requires the BIOS from the real console in the data/bios directory. Selection of a BIOS rom will be required on the first run. The ROM can be changed under Options->BIOS or by modifying the config.json file.

Avocado doesn't support fast booting. UniROM can be used as a work around. Place the .rom file in the data/bios directory and modify config.json:

"extension": "data/bios/unirom_caetlaNTSC_plugin.rom"

Press the Start button (Enter by default) to fastboot, or R2 (keypad *) to slowboot a game. You can run the included PlayStation firmware replacement Caetla with the Select button (Right shift) then run the .exe directly from the disk.

To load a .cue/.bin/.img file just drag and drop it.

Keybinds

  • Space - pause/resume emulation
  • F1 - hide GUI
  • F2 - soft reset
  • F7 - single frame
  • Tab - disable framelimiting
  • Q - toggle full VRAM preview
  • R - dump RAM and SPU RAM to file

Avocado maps any Xbox 360-like controller to the PlayStation Controller. A keyboard can also be used (modify the keymap under Options->Controller).

Issues

This emulator is not very mature yet!
