Вся информация - в наших подробных обзорах. Behold a small guide/faq of the sync options in retroarch for silky smooth console experience. diodrivertinyalsa as a new line to your system/nf file. I had contributed a few fixes for Snes9x that fixed a few inconsistencies that I caught.Įdit: Just thought of another idea, validate the graphics and sounds as well.84% Test: Samsung Galaxy Tab S7 Plus – Oklanderlig lyxplatta But if a core can pass them, then it will have very consistent save states. Some people found that turning up their latency (Settings < Latency < Audio Latency < Audio Latency (Ms)) helped their audio problems. Music production applications typically have the same deal. That is, it actually controls the audio buffer size, which does have a relationship with delaying the audio, but its a bit more complex than '500 ms buffer half-second delay on audio'. It would be a huge mountain of work to get cores to pass all the tests. AFAIK, the audio latency option in RetroArch is not a straight-up ms-for-ms delay. QuickNES passes without any hitches at all, and Snes9x passes most of the time if you modify the emulator to never skip frames. GGPO-like netplay (latency hiding rollback). Most emulators fail the tests, but a few pass successfully. Then once it finds a difference, it triggers a debug breakpoint. Then after creating two save states, it compares them byte-by-byte for any differences.

(Secondary core on, Runahead 1) Compare Run, Save State, Run, Load State against another instance which never loads state.

(Secondary core on, Runahead 0) Compare Run, Save State, Load State against another instance which never loads state (this catches a lot of issues).

(Secondary core off, Runahead 1) See if Run, Save State, Run, Load State, Save State produces the same two savestates or not.

(Secondary core off, Runahead 0) See if Run, Save State, Load State, Save State produces the same two savestates or not.

It has four tests it can perform once Runahead Debug Mode is turned on (enable advanced options to see this setting) It's available from /dwedit/retroarch/tree/debug-runahead-2, but pretty much needs to be run in a debugger to be of any use. The purpose of the fork is to catch save state inconsistencies. PlayStation PSP Compilation / Development Guide¶ Environment configuration¶ You need the homebrew PlayStation PSP SDK and toolchain installed. I had made a 'Debug Runahead' fork of Retroarch. FBA should not depend on retro_serialize_size being called first, and RetroArch runahead should be made consistent with the other ways it saves state. RetroArch (formerly SSNES) is an open-source, multiplatform modular application capable of emulating various systems created by the Libretro development team. I don't see anything in the API documentation that says you must call retro_serialize_size before calling retro_unserialize, but in practice, RetroArch is calling core_serialize_size before doing anything with savestates. Yes PPSSPP has an unusual high input lag: PPSSPP: 6 frames of internal latency. RETRO_API bool retro_unserialize(const void *data, size_t size) Options for decreasing input latency related to vsync by eliminating buffering by the video driver, as well as. RETRO_API bool retro_serialize(void *data, size_t size) GGPO-like netplay (latency hiding rollback).

* retro_serialize_size(), it should return false, true otherwise. RETRO_API size_t retro_serialize_size(void) * value, to ensure that the frontend can allocate a save state buffer once.

* returned size is never allowed to be larger than a previous returned * Between calls to retro_load_game() and retro_unload_game(), the * Returns the amount of data the implementation requires to serialize
