Most Recent Changes

simple64 now has a dedicated Discord server.

Netplay announcements and general discussion will happen here. I'll be hanging out in there, so come chat!

Tip: If you're struggling with performance, try unchecking "SynchronousRDP" in the Settings->Core and Video Settings->ParaLLEl Video. Some games require this option, many don't, disabling it can increase your FPS.

• Fix for emulation thread being stuck in the background if a game freezes.

--4ac8922--

• Some performance optimizations

• Support for 64DD cartridge ports; see DUMPs and TRANSLATIONS links. You can safely ignore the warnings about emulator support on that page, simple64 now supports saving with 64DD cartridge ports. This means you can play these 64DD games like you would any other game.Technical details for those interested: 64DD cartridge ports write to the ROM, which is normally not allowed. On flash carts, as far as I know, this is accomplished by modifying the ROM file on the flash cart. simple64 creates an xdelta file and saves it as a .romsave file along with other saves (eep, fla, mpk) if the game writes to the ROM. When the game is loaded, if a .romsave file exists for that game, xdelta is used to apply the differences to the ROM in memory. The xdelta is always taken based on the Big Endian/z64 ROM image, regardless of the file type of the ROM. This should be an emulator agnostic way to save these files, and could be standard used to allow these saves to be cross-emulator compatible.

--ac08158--

• Some performance optimizations

• Fix for refresh rate calculation, see #299 for details (NTSC games now refresh at slightly under 60 FPS, as per the NTSC standard)

--830e68d---

• The emulator has a new name! simple64. People were often confused about the difference between the upstream mupen64plus project, and m64p. This new name should help people differentiate the 2 when discussing them. I think the auto updater should work, but to be safe, I would recommend downloading this release as a fresh install.

• The exe is now called simple64-gui.exe. If you use the auto-updater, your folder will still have the old mupen64plus-gui.exe. You can delete the old exe, or just download a fresh copy of the emulator to clean up the folder.

• Fix for the broken application icon in the previous release

--fbf2c91--

• Current USA games list of known issues #288

• Some performance improvements that should slightly lower the CPU usage

• Fix for a regression in the last release (caused freezing/lockups in some games)

• This release marks the removal of the last game-specific hack/setting. There was a hack in place that prevented flickering in San Francisco Rush, which is no longer required.

--a167eb6--

• Tweaks to how RDP (graphics) are timed. Fixes Tetris 64, may provide slightly improved performance when SynchronousRDP is enabled.

• Tweaks to memory access timing based on (https://github.com/rasky/n64-systembench)

--f7ff318--

• Fixes for some tests in Lemmy's system-test ROM (https://github.com/lemmy-64/n64-systemtest). Probably won't impact any commercial games but you never know.

--fa634d0--

• Fixes for the following games: NFL Quarterback Club 1999/2000/2001, The Powerpuff Girls - Chemical X-Traction. 

--7200055--

• Performance improvements for games that make heavy use of TLB addressing (Indiana Jones for instance)

• Some small timing corrections

--75f3045--

• Some performance improvements based on code analysis

--af7a38d--

• Improved synchronization between CPU and RSP tasks (fixes a lock-up in Pilot Wings and hopefully other unreported issues)

--8a0092e--

• Fix for shader stutter on Nvidia GPUs

• Further tweaks to timing, removed game-specific hacks for some RSP and audio timing issues that existed in the past

• Properly emulate PI DMA timing

• Better estimation of RSP task timing

--272704f--

• Fix for an error/freeze created in the last update

--4374d1f--

• Further tweaks to timing

• Extremely rough estimation of RSP timing

• I want to be clear that "better timing" doesn't mean "perfect timing". m64p is still not cycle accurate, and never will be, it's just much better at guessing the correct cycle count now. There still may be areas where the cycles aren't counted correctly.

--b54f435--

• Fix save states

• More timing tweaks

• Fix for HiDPI screens

• Fix randomization

--68d5465--

This is a significant reworking of the timing code in the emulator. "CountPerOp" has been removed. The N64 instruction and data cache have been fully emulated. Timings for DMAs have been corrected.

Timing is now much more accurate, for example, in the DK64 intro, Donkey Kong now correctly grabs the vines and swings across the water.

This was the result of many weeks of work. I looked at CEN64, Ares, and lots of independent research. It's definitely not perfect, but a massive step toward accurate timing in the emulator. I would appreciate bug reports if issues are discovered.

m64p strives to be an accurate emulator. Many original N64 games lagged at times. If a game has a low framerate, but the audio sounds good, this is likely in-game lag, and it is not a bug. Choppy/popping audio is likely a bug.

--3f1da83--

• Support for libdragon rspq. This is a library used for homebrew games

• Reworking of RSP timing code, should offer performance improvements in some games - Gauntlet Legends for instance

• Small accuracy improvement for audio and RSP DMAs

• The new RSP code requires a version bump of the netplay servers, you'll need to update to this version to continue using netplay

--7f8d774--

• Fix auto updater - you'll need to manually update to this version before it starts working again

• Fix issue when configuring controller profile where inputs were sometimes picked up twice

--ee48c6a--

• This release includes a new feature I'll call "Dynamic SI DMA Duration" for now. The SI (Serial Interface) is the hardware that communicates with the game controllers. The emulator now dynamically calculates an optimal value for how long data transfers should take. This greatly improves performance when using the Raphnet adapter (used to play with a real N64 controller). It also improves the performance generally in some games, for instance, Body Harvest CPU usage is roughly halved.

--6d24363--

• Fix resolution setting

• Fix bilinear filtering setting

--d338364--

• Add back screenshot support using Vulkan

--03c83c8--

• Built using Qt6 (instead of Qt5).

• Native Vulkan rendering. The shim that was in place to present the final image in OpenGL has been removed. Everything should look the same, but this is a fairly large change under the hood. Please report any bugs you find.

--34537a7--

• Fix for the Windows build of the previous release.

--5228957---

• Just a small fix for the last release to fix an issue with Wayland on Linux

• Just some minor fixes for the Snap package

--5abda88--

• Fixed a bug that caused Rumble to stop working on some controllers.

--661626c--

• Fixed a bug that totally broke netplay. It is no longer totally broken.

--c884318--

• mupen64plus-core has changed (added a CPU overclocking option), necessitating an update to the netplay backend. The netplay servers have been updated. This means that you need to update to at least this version to continue using netplay.

--03e01ab--

• Updates to ParaLLEl RDP, mostly to improve graphics card compatibility (fixes for newer Intel GPUs)

--467160c--

• Update custom ROM settings (performance improvements) for Smash Remix 1.0.0 and 1.0.1

--2d663d3--

• Just some minor fixes for the dynamic recompiler

--fe21338--

• Linux builds now built using Ubuntu 20.04

• Fix for corrupt screenshots and/or crashing when using non-native window resolutions

--53d1c29--

• IS Viewer support. You can view the output from IS Viewer by going to Emulation->View Log. This log view is now updated live, so you can leave that window open while you play

• Some bug fixes for the dynarec, including Indiana Jones crashes and Densha de Go (English) not booting.

• Improvements to VRU speech recognition

• Fix for flickering in San Francisco Rush

--b16fb1c--

• This release now includes mupen64plus's "new dynarec". It's enabled by default for new installs. For existing installs, you can enable it by going Settings->Core and Video Settings and setting "R4300Emulator" to "2". This should reduce the load on the CPU for most games.

• A first for any N64 emulator: VRU (Voice Recognition Unit) support! Only 2 games made use of it: Hey You, Pikachu! and Densha de Go! (English translation here. Both of these games expect the VRU to be connected to controller port 4:
  Once you click "Emulate VRU", it will begin to download an English language voice model, which is required for speech-to-text recognition. It only does this the first time.
  It will download the model into the same directory as the EXE, so that directory needs to be writeable.
  You need a microphone to use the VRU. You can search on YouTube for some gameplay footage of Hey You, Pikachu! to see how it's used.
  Only English is supported.

--938c08c--

• A couple of minor emulation accuracy improvements for PI and RSP DMAs. I'm not aware of any impact on games.

• Widescreen support (you'll find it in the ParaLLEl Video options). This is the equivalent of setting your TV to "force 16:9". This would normally be used on a game like GoldenEye, which has a widescreen option in the pause menu. Using this on a regular 4:3 game is just going to stretch the image.

--861373c--

• This release adds support for games created with the libdragon toolchain. These are homebrew/fan made games. An example is here.

• There are quite a few games created with this toolchain, you can google "N64 homebrew" to find some.

• If you know of other homebrew games that have issues, I'd be curious to hear about them!

--4b6ad5c--

• Hopefully some more audio improvements (popping & crackling)

• Fix saving in Pokemon Puzzle League

• Full support for Unicode characters in filepaths on Windows

• Fix for shaking video when interlacing is enabled

--5d65750--

• Fix for crash at 8x upscaling.

--768852c--

• Performance improvements when using upscaling in ParaLLEl-RDP.

• Some tweaks to the audio code to try and reduce crackling in some cases.

--094325c--

• GLideN64 (and Angrylion Plus) has been replaced by ParaLLEl-RDP
  You can read about ParaLLEl-RDP here.

• The emulator now requires Vulkan 1.1 to run. This means if you have an Intel GPU, you generally need a Skylake or newer processor. If you have an Nvidia GPU, you generally need it to be Kepler series or newer. If you have AMD, I have no idea. You may want to update your graphics drivers if it's not working.

• By default, ParaLLEl-RDP displays the game in native resolution, you can change this by going to Settings->Core and Video Settings->ParaLLEl Video->Upscaling, and changing the value of "1" to "2", "4", or "8".

I understand that this will be very exciting news for some, and for others, it will be disappointing. ParaLLEl-RDP has higher system requirements than GLideN64. I know some people will wonder why I didn't just include both. From the beginning, I set out to create a very easy-to-use, accurate emulator. Since the dawn of time, the plugin system has been a source of complexity and confusion in the N64 scene. Most of all, I am creating an emulator that I enjoy using.

I am trying to reduce the complexity and provide an accurate and playable emulator for a majority of people. It's not going to be perfect for everyone. Both Project64 and RetroArch provide good N64 emulators that include GLideN64 bundled in.6a5db81
