Hey all. I maintain a small shadPS4 fork that I test on an RTX 3080. I did the debugging for this release with Claude (Anthropic's AI). New build with the launcher included:

The Order: 1886: the random black triangle / gray rectangle

If you've played The Order on shadPS4, you've probably seen it: every few seconds, for a single frame, a huge black triangle or a fog-gray rectangle flashes over the scene. It was worst around the door in the first chapter, at about one frame in ten. (Images 1 and 2.)

Finding it took a while:

Recording the frame in RenderDoc and replaying it gave a different result each time: about 1 replay in 10 showed the triangle, with exactly the same commands and data.

Bisecting the replays showed that one small instanced draw (24 indices, 6 instances) was writing a broken triangle into the depth buffer.

That draw's vertex shader contains a GCN "waterfall" loop. It picks the first active lane's instance id (readfirstlane), the lanes with that instance do their work, and the loop repeats.

On the PS4, all lanes of a wave always run together, so this is safe. On NVIDIA, when the loop runs more than once, it sometimes read another vertex's instance id, and that vertex shot across the screen.

The proof: in RenderDoc I swapped only that cross-lane read for the vertex's own value, and the triangle went from about 10% of replays to 0 out of 120.

The fix: which vertices share a wave is up to the hardware, so no correct vertex shader can depend on its neighbours, and a wave with a single active lane is a perfectly valid PS4 execution. The emulator now runs each vertex as its own wave, so these loops always read the vertex's own data. It's a general fix in the shader recompiler, with no game-specific hack, so any game whose vertex shaders do this benefits.

Also fixed in The Order in this release:

Enemy faces turning black: a shader compiled in the background read the game's texture descriptors after the game had already changed them.

Occasional frames with black or unlit patches, caused by a GPU command reading data that had already been reused.

Two crashes, one of them in a later area.

Need for Speed Hot Pursuit Remastered: black world

The game drew only the HUD and the rear-view mirror; everything else was black (image 4). For some draws the game uses the PS4 driver's built-in shaders, which the emulator keeps inside its own executable, and a safety check thought those addresses were invalid and skipped every one of those draws. They're allowed now.

Readbacks

Every game now runs with at Auto GPU readbacks, so The Order and NHL 24 no longer need a custom config. NHL 24 plays a full match with clean ice on relaxed instead of precise.

Tested on this build (images 3, 5–7)

The Order: 1886, NHL 24 (a full match, no crash at the end of the third period), UFC 4, inFAMOUS Second Son, The Grand Tour Game and NFS Hot Pursuit Remastered. All on an RTX 3080 / Windows.

Notes:

The first run after updating recompiles shaders, so expect some hitching in that first session.

It's a fork, not an official shadPS4 build,

Wanted to know if anyone knows of a ds/3ds emulator that will work with dual monitor. Like have the bottom screen on one monitor and top screen on another.

This is a fan project made by me and can be found on my github!

Hey everyone!

I’m looking for a reasonably priced projector for retro gaming. I want to connect it to my MacBook Pro M4 Pro and play emulated retro games on a big screen.

My main priority is low input lag, especially for fast-paced games like platformers, fighting games, and classic action games. I don’t need a high-end home theater projector, just something affordable that delivers a smooth and responsive gaming experience.

Ideally, I’m looking for:

Low input lag for responsive gameplay.

A decent image quality and resolution.

Good value for money — nothing too expensive.

Compatibility with my MacBook Pro M4 Pro.

Does anyone have recommendations for budget-friendly projectors that work well for retro gaming? Are there any specific models I should look at, or features I should prioritize to minimize input lag?

I’d really appreciate any suggestions or personal experiences. Thanks!

Hi, lately I have managed with Claude Code generate own game launcher using external emulators like Dolphin and other 11 emulators to match the best solution for "plug and play". Just by "uploading" (selecting) local games or emulators and the software would do the best to install, make it ready to use.

Just bcs sometimes the solution is a little bit triccky than just downloading the Emulator binary.

🔹Yes, the software looks like PlayStation 3 home screen and Steam Library

Everything is great, I have so many ROMS for personal use but...

🔸Lets chat what could go bad with the software.

I mean I could share the BetterPlay with friends, but they have to find their ROMS and not emulators themself?

Or is there option where it could simply list the existing websites since they are the source of products?

Little bit information about BetterPlay

BetterPlay for this time is in JavaScript, but already support:

- Linux support mainly for Steam Deck 🔥

- Virtual card slots support (PS like, where games need the storage card to play, this is bypassed to own local folder).

- Remapper for Controllers, I own Steam Controller (2015) and I am trying to get the best control support for example into Super Mario Galaxy where you need movement, attacks but also gyroscope.

- Sub archives, simply you put in specific folder . zip or .rar with the game(s), than it would scan the archives for the specific types of files (games or emulators) and it would appear in your library.

- Own tracking how long you have played the game

- Local save folders (simply better, when you install binary it asks you for your folder where would you want to put those subfolders "Emulators" / "Games" / "Saves"

Note: This project is mainly done for my personal use, bcs I want to play the old games like The Simpsons Hit and Run on my main PC or Spore 👀 on some kind of Console.

POKEMON PINBALL NO SPLIT IS AN EMULATOR FOR POKEMON PINBALL GBC ON ANDROID AND WINDOWS.

ROM IS NOT INCLUDED.

Pinball NS - https://github.com/ReiniShari/Pinball-NS

A mod of Pokémon Pinball (Game Boy Color, US version) for Android and Windows, written in C with an emulation core in assembly.

In the original game, each table is split into a top and a bottom stage: only one is loaded at a time, and the screen goes blank while the other is loaded. Pinball NS turns each table into a single field: both halves are loaded, updated and shown together on one tall screen, and the ball moves between them without any reloading. The original physics and collisions are kept, so the table plays like the original.

The whole table on one screen, the score bar under the table.

Objects, lights and animations of both halves are always running; flippers moving even when the ball is at the top.

The top of the "SLOT" cave halo, never visible in the original, completed by symmetry.

Smooth pacing on 60, 90, 120 and 144 Hz screens, with the sound following the picture.

Android: the game fills the width of a portrait screen, extended to the edges with its own graphics, with touch controls styled after each table.

Windows: the table alone in a resizable window, keyboard and gamepad, key mapping tool.

The ROM is never modified: the program contains a Game Boy Color emulator and hooks the game's routines.

WHAT'S NEW IN v2.7

Sound: steady pitch and tempo (Bluetooth outputs, screens changing their refresh rate, after the menu), the bass closer to the Game Boy Color, no silence added.

Touch controls answer on their drawn shapes only; TOUCH FLIPPERS option (the left and right halves of the game).

• New options: MOTION TILT (shake the phone to tilt), SCREEN FILTER (dot, LCD), COLORS (black and white, Game Boy green), and an ABOUT page.

Next to come : iOS version, Generations compatibility

Please enjoy, any feedback is appreciated

(AI has been used for assembly core optimisation, test - debug - general optimization routine and various tasks ;-))

Brother my game is turning on properly but i am stuck on the first screen. The game tells me to shake my controller but i am on kbm so i couldnt really do anything and im stuck on the first screen. Can u tell me how can i fix it.

Hello everyone, please help me understand why my wife’s Xbox rog ally seems to be performing worse at emulation than the Thor which has lower specs (Android handheld vs pc handheld)
