==FeaturesDownload==*Consistency across multiple platforms, using the same UI structure and a fully featured command line interface.*Gamepad controlled menu system with multiple styles available, such as XMB or Material UI. (There's also a [https://www.youtube.com/watch?v=hfuioGjCItw QT-based 'WIMP' desktop-style interface] for PC platforms that was announced before and released in version [https://www.libretro.com/index.php/retroarch-1-7-3-released/ 1.7.3].)*Gamepad auto-configuration profiles, so that gamepads are mapped automatically when connected. XInput controller autoconfig is built into the application, with other controller types available as external profiles.*Per-core and per-game configuration overrides*Custom resolution and refresh rate for video output, with exclusive fullscreen mode and monitor index for multi-monitor setups.*Dynamic rate control for smooth audio and video, even when the game's output rate is different from your system. Especially obvious with systems like GBA that do not run 60Hz.*Basic fast forward, SRAM saving, savestate, etc. It supports serialization of the emulation state which is used to provide real-time rewind and netplay.*[[Shaders and Filters|Pixel shaders]], primarily using Cg and GLSL, with HLSL on Xbox 360. The shader format it uses is flexible and fairly easy to use, allowing for complex multi-pass effects with adjustable runtime parameters. Also supports traditional video filter plugins that are run in software.*Supports audio DSP filter plugins through .dsp configuration files.*Custom overlay support.*FFmpeg recording and playback support. It can record either the native resolution output of the core or the post-processed output of the frontend. Playback is handled through an internal FFmpeg libretro core.*Streaming support. By adding your twitch account to RetroArch and making some small [https://www.retroarch.com/index.php?page=recording setup], it is possible to stream on Twitch the content of the game played.*[[GGPO]]-like netplay (latency hiding rollback). It should be lag-free if everyone involved emulates at full speed, doesn't live on opposite sides of the world and has decent internet speeds. It uses peer-to-peer UDP and supports two players. Due to rollback, it requires a fair amount of CPU power to run, and the core must support serialization.*Options for decreasing input latency related to vsync by eliminating buffering by the video driver, as well as using frame delay to delay polling of inputs until right before a vsync occurs on the display.*Run-ahead to reduce latency. This setting allows cycle-accuracy emulators to run ahead of mandatory 1 or 2 frames of input lag. It allows emulators to [https://www.libretro.com/index.php/retroarch-1-7-2%E2%80%8A-%E2%80%8Aachieving-better-latency-than-original-hardware-through-new-runahead-method/ achieve better latency than original hardware] (Official debut in version 1.7.2).

==NetplayCompatibility==Netplay is now usable from the menu in current builds, under Settings>Netplay Options. You can get it to work with the [https://github.com/libretro/RetroArch/wiki/Using-command-line command line] or the long-deprecated [http://www.mediafire.com/download/yrydc78bl6y82z4/retroarch-phoenix.7z RetroArch-Phoenix Launcher] as well in older builds.

You must specify whether you will be hosting (server) or joining (client) the game* <b>[https://psp-archive. If joining, you must also enter the host's IP address in the field below. Make sure your firewall is open on port 55435 (default; you can change it if you like) and that the port is forwarded in your router, if applicable. You can also specify 'spectator mode,' which will allow an arbitrary number of spectators to join and watch you play without being able to play themselvesgithub.io/nulldce-psp/ Official Compatibility List]</b>

Similar to the GGPO platform, RetroArch creates a constant stream of savestates which, along with button presses, are exchanged and compared between the server and client machines*<b>[https://github. If the savestates start to diverge, the com/PSP-Archive/nulldce-psp/issues Open new game rolls back in time to a point where they both agree and then the libretro cores emulates the missing frames all at once to get back to the appropriate spot. This gives the illusion of completely lagless inputs, which is invaluable for twitchy, fine controls.issues on Github]</b>

If you try to connect to a server nullDC-PSP is only compatible with 'slim' models (PSP-2000 and it immediately says client disconnected, open your log and make sure your ROMs match exactly (it will complain about a hash mismatch otherwiseabove).

==Alternative Launchers and FrontendsBIOS== There are plenty of other frontends that can either work as a launcher for RetroArch or you can replace it entirely with another [[Frontends#Libretro|libretro frontend]].

{{Main[[Emulator_Files#Nintendo_DS_.2F_DSi|Frontends}}Required DreamCast BIOS]] files are needed in the <b><code>nullDC/data</code></b> folder :<B>*dc_boot.bin*dc_flash.bin</B> ==Game Files== Only games in the <code><b>.gdi</code></b> format are supported for now. Place the files for each individual game within a separate folder, and move the folder to <b><code>nullDC-PSP\discs</code></b>. The list of available games will then appear when you boot the emulator. [[File:GUI.png|320px]] ==Controls== Idle time can be adjusted with the L / R buttons. To start the Dreamcast BIOS, press triangle as the emulator is booting.
