COMMON: Fix buggy behavior that could happen with ZIP file reading on some platforms as a result of not initializing struct.COMMON: Added runahead system allows you to drive down latency even further.COMMON: Add OSD statistics for video/audio/core.

COMMON: Fix invalid long command line options causing infinite loop on Windows.

COMMON: Add way to reset core association for playlist entry.

COMMON: Hide the ‘Core delete’ option if the ‘Core updater’ is also hidden.

ANDROID/OPENSL: Prevent crashes when setting audio latency too low (buffer count can never be lower than 2 now).

The quick rule of thumb is that the faster the core, the higher chance there is to get it to run at fullspeed with more runahead frames. Your mileage may vary on any of the other cores. Based on our performance tests on the PS3 and Xbox OG, QuickNES and Gambatte should be at least two cores that should run at fullspeed with runahead set to 6 frames or less.

An often heard question that has been asked is – will this work on a Raspberry Pi? There is no straight answer to this since it heavily depends on the core’s performance.

This might likely change once our bounty for the Beetle PSX dynarec is finally fulfilled (and on that note, it has already reached $720, and a coder is working on a potential solution) Second, even after several savestate performance improvements, it is unlikely you will be able to set runahead to higher than 1 frame while still being able to run at fullspeed. The OpenGL and Vulkan renderers are currently buggy with runahead. First of all, in order for this core to work correctly with runahead, you should use the software renderer.

There are currently some things you should know about Mednafen/Beetle PSX when it comes to runahead.

Some of these cores include (but are not limited to) the Snes9x cores, QuickNES, FCEUmm, Nestopia, Gambatte, and even Mednafen/Beetle PSX. To this end, Dwedit has submitted several patches to some of the cores in order to make them perform much better.

While the runahead system is core agnostic and therefore technically we don’t need to patch up cores in order to work with the runahead system, there are several things that can be done in order to improve performance considerably.

The higher performance you get with a core, the more frames you can run ahead at fullspeed. These performance demands go up commensurate to the amount of frames you want to run ahead.

For playable performance, your system should be at least capable of running the core at twice its regular speed.

You can count the amount of lag frames a game has by using the frame advance feature in RetroArch. So, for example, if a game like Super Mario World for the SNES has a guaranteed 2 frame input lag, for the best results, set Runahead frames to 2. In order for the runahead system to perform as expected, you should set it to the same amount of frames to read ahead that the game you’re running is working by.

Every game has a certain built-in amount of lag frames.

Here are some basic things you should know: The versions that have this feature enabled and exposed now includes: Secondly, the feature has now been enabled for the vast majority of the RetroArch platform ports. First of all, several performance improvements have been made since. We ran an article on this new feature before, and since then, several facts have changed on the ground which bears pointing out.

Well known people like Durante of DSfix fame praised it and the popular site Ars Technica has dedicated an entire article to this game-changing feature. This feature has already been all the rage over the Internet. If you are using an existing installation of RetroArch, it is worth going back to the main menu and going to ‘Online Updater’, then selecting ‘Update Core Info Files’ and ‘Update Databases’ to ensure everything is up to date with RetroArch.This might just be our biggest release yet, thanks in no small part to the new runahead latency reduction system. Select this and the PPSSPP core will download and install to RetroArch. Next, navigate down the Core Downloader list until you reach ‘Sony – PlayStation Portable (PPSSPP). You can do this by selecting ‘Load Core’ and then ‘Download a Core’. To play PSP games with RetroArch, you will ideally want to use a controller – The 8bitdo Pro 2 Bluetooth Controller is an excellent controller, is available in a cool retro PS1 style, and can also be connected by USB.Īs soon as you have RetroArch installed, we are ready to download the PPSSPP core in RetroArch.Have at least one PSP game ready to use – The PPSSPP core will boot.Install RetroArch – Download RetroArch Here.Here is what you will need to have ready:.
