Metal Gear Solid: The Twin Snakes is a stealth action video game. The Twin Snakes is a remake of Metal Gear Solid, developed and first published by Konami in 1998. The Twin Snakes features graphical improvements over the original, new cutscenes written and directed by Ryuhei Kitamura, and gameplay functions originally introduced in the sequel Metal Gear Solid 2: Sons of Liberty. The game also includes a revised translation with re-recorded voice acting using most of the original English voice cast.



Crashes occur in cutscenes and when continuing. Many cutscenes can be skipped, but there are some mid boss battle cutscenes that you cannot skip at all, albeit these are very short. To fix this, use the DSP LLE audio engine; people talk in game and cause the crash since the emulator can't handle it. (This may need further testing). Setting the DSP Engine to "Xaudio2" may reduce DSP HLE's crashing problems.

Error Message

On startup, several of the below two messages appear. Disable "Use Panic Handlers" to hide these messages.

BackPatch: Base reg not RBX, Attempted to access 3f47e054
BackPatch: currently only supports reads, Attempted to write to 3f47e054

Battle Glitches

During the Cyborg Ninja and Psycho Mantis fights, a glitch may occur that prevents you from damaging the bosses. The bosses may also get stuck in a loop. There is no known solution to these problems; the only way around it is to keep trying, and you should eventually be able to beat them.

Thermal Goggles

With EFB Copies to Texture Only, wearing the Thermal Goggles turns the whole screen blue, making it impossible to see both in first and third person modes. Disable EFB Copies to Texture Only to fix it.

Windows 7 Intel Pentium E6300 @ 3.3GHz ATI Radeon HD 4850 Stable and very close to solid 60FPS (except in cutscenes) with OpenGL, HLE XAudio2, Fast Safe Texture Cache, and Lock Threads to Cores. Toggle EFB to RAM for Goggles. axfelix
r7310 Windows 7 Intel Pentium E5300 @ 2.6GHz ATI Radeon HD 5450 Good,you have to enable MMU hack or the game crash at the title, the game don't have any problem but i can play at 30FPS--> 60% speed with DX9 plug-in Markon89
r7387 Windows 7 Intel Core 2 Duo P7450 @ 2.13GHz NVIDIA GeForce G210M Bad, working better in OpenGL mode. Anyway, FPS meter says 28FPS but game have a weird -annoying- slowdown; minor sound glitches and nano-communication background texture generally turns in a bad, green color bfrheostat
r7393 Windows 7 Intel Core 2 Duo E7400 @ 2.8GHz NVIDIA GeForce 9600 GT Speed 70-100% FPS 25-50 DX9 plugin, good emulation and very playable Licous

r7671 Windows 7 AMD Athlon X3 455 @ 3.5GHz AMD Radeon HD 6850 Above average, minor sound skipping in the cutscenes when frames drop, no crashes or error messages encountered, some transparency problems around certain objects in game, 50-60FPS otomo
r7690 Windows 7 Intel Core 2 Duo T9400 NVIDIA GeForce 9800M GTS No Problems, but only 35-60FPS!
^r7683 Windows 7 AMD Phenom II X4 955 @ 3.2GHz ATI Radeon HD 5770 Bad, codec conversations stops after some seconds, sound glitches, game crash in cutscenes, 30-50FPS 0005
^3.0 Windows 7 AMD Phenom II 1055t @ 3.5GHz AMD Radeon HD 6870 Fully Playable 55-60FPS with very minor visual artifacts on some cutscenes. Sound is buggy most of the time, even when using the LLE engine. HLE sounds better during general gameplay but LLE fixes the crashes during cutscenes. Using DX9 with with cache display lists and OpenMP texture decoder enabled.
3.0-201 Windows 7 Intel Core i5-2500K @ 3.3GHz NVIDIA GeForce 470 GTX Playable, no cutscene crashes. Texture Glitches on closeups. Overall Music and sound glitches, heavy sound glitches and major slowdown on alert and weapon firing, also sound (+subtitles(!)) lags behind in cutscenes; Audio/FPS throttle doesn't fix this. 50-60FPS
3.0-373 Mac OS X 10.7.2 Intel Core i7-2675QM @ 2.2GHz AMD Radeon HD 6750M Playable. 47-60FPS. Little to no slowdown during the introduction or first section of the game in the heliport. jedivulcan
3.0-377 Windows 7 Intel Core 2 Duo E8500 @ 4.23GHz NVIDIA GeForce GTX 285 2GB Playable. Mostly smooth, with occasional slowdown. Music cuts out frequently, sometimes permanently, and sound and music crackles. Lycan
3.0-458 Windows 7 Intel Core i7-2600K @ 3.40GHz NVIDIA GeForce GTX 580 1.5GB Full speed gameplay, but cutscenes freeze after a few seconds and the sound is glitchy. Though I'm using the default Dolphin download with no modifications whatsoever. Gwame
3.0-631 Windows 7 Intel Core i5-460M @ 2.53GHz Intel HD Graphics(Core i5) 1.3Gb Playable. Just a minor sound glicht in codec conversation and cutscenes, but gamemplay is good. Fox zero
3.0-688 Mac OS X 10.7.4 Intel Core i7-2675QM @ 2.2GHz AMD Radeon HD 6750M Playable. Slow in a lot of areas. Shutters. Audio glitches. I really question what kind of drugs I was on to comment that this worked really well on revision 373. jedivulcan
3.0-710 Windows 7 Intel Core 2 Quad Q9550 @ 2.83GHz NVIDIA GeForce GTX 580 1.5GB Full speed gameplay with accurate vbeam emulation enabled. FPS is heavily CPU dependent, but constant enough to be very playable. The issue where sound skips/cuts out during cutscenes can be fixed by either using DSP LLE or changing the backend to Xaudio2 if you want to use HLE Emulation. Whall005
3.0-739 Windows 7 AMD FX 4100 @ 4.22GHz NVIDIA GeForce GT 520 Full speed gameplay with accurate vbeam emulation enabled. FPS 59.9-60FPS at all times with no decrease, 1600x900 resolution and default settings The issue where sound skips/cuts out during cutscenes can be fixed by either using DSP LLE or changing the backend to Xaudio2 if you want to use HLE Emulation.
3.0-844-newaxhle Windows 7 SP1 Intel Core i5-2500K @ 3.7GHz NVIDIA GeForce GTX 580 1.5GB Perfect emulation, no crashes, full speed the hole time. MMU speed hack needed to boot correctly into the game. EFB copies to RAM not texture to fix thermal goggles issue. Disable widescreen hack to avoid double images in cutscenes.

Important: to avoid sound cutoffs, do the following: VBEAM accurate emulation turned ON in rom settings DSP recommended: NEW AX HLE 3.0.844 Framerate limit to: Audio not Auto(with "Limit by FPS" turned on to avoid audio faster than video as in lips desynched with audio). Audio backend: XAUDIO2 If still experiencing sound stuttering, try PAL version of the game, have tried both NTSC and PAL, and Pal is better in regards of avoiding sound stuttering. ONLY slowdown is in cutscenes that have real footage but there are only four of them and they are short.

3.5-1123 Windows 7 Intel Core i5 @ 2.7GHz ATI Radeon HD 5750 Better than previous builds "out of the box". Stable and 30FPS. Slight audio cracking and popping. TonyTheTerrible
3.5-1154 Windows 10 Intel Core i3-2110 CPU @ 3.10 GHz NVIDIA GeForce GTX 650 2 GB The only revision I could use to get this game to a playable state, as of the time I typed this. Near-flawless cutscenes with occasional slowdown. Gameplay near-flawless, but subject to slowdown when left on long enough and/or in a gun fight with enough people shooting at you. LLE to prevent cutscene crashes, though using HLE, crashes are much less common than other revisions, but not unheard of. Tested until the end of the cutscenes after fighting Ocelot. The only Live-action sequence during said cutscene (When Baker explains how the nuclear waste is being stored away poorly) is prone to slowdowns/audio cutting off every few seconds and video freezes. Subtitles keep going as normal however, so it stays bearable. Restart the game frequently, as the audio becomes progressively more static. Pokefrazer
3.5-1344 Windows 8 AMD Phenom II X4 955 @ 3.4GHz AMD Radeon HD 6950 2GB Full speed gameplay, perfect gameplay. FPS stable at 50-52FPS, 25-27 on cutscenes, playing perfectly. My settings : VBEAM speed hack enabled (right click -> properties on the ROM). Config : Framelimit = "Audio" & "Limit by FPS". GFX = D3D9, 1920x1080, Stretch to window, Internal Resolution = "Auto (Multiple of 640x528)", 4xMSAA, 8xAF, Scaled EFB. NO widescreen hack or you'll get double screen on cutscenes and general graphic glitches, use "stretch to window" instead. For hacks, EFB copy to RAM, accuracy fast will suffice. For DSP use LLE, On Dedicated Thread, XAudio2. Alexbeav
^3.5-367 Windows 8 Intel Core i5-2500 @ 3.3GHz NVIDIA GeForce GTX 660 Perfect emulation, No Problems, 60FPS! Internal Resolution = "Auto (Window Size)" 1920x1080p. Cronö
4.0-146 Windows 7 Intel Core i7-920 @ 2.67GHz ATI Radeon HD 5850 Full speed. But there are a few cases where there's annoying bugs/crashes. In particular is the fight with the stealth soldiers in the elevator. They will most of the time end up not spawning at all, causing you to reload multiple times until they do. Another thing I'm currently stuck at is the fight with Vulcan Raven (2nd battle, inside the frozen hangar). It crashes the emulator the moment Raven starts to shoot his minigun. Ryudo
^4.0.2 Windows 7 Intel Core i7-4710MQ @ 3.4GHz NVIDIA GeForce GTX 860M Perfect all the way through save for some crackling audio and jerky framerate during certain live-action footage. Tested at 2X native with the OpenMP hack on. All other options on default. Andy
4.0-2720 Windows 7 Intel Core i3-2120 @ 3.2GHz Intel HD 2000 Always full speed emulation @ native resolution. A few minor glitches: Quickly appearing green lines on title screen, cracking sound while saving, graphical bugs after climbing the ladder which leads to the roof of Comm. Tower B, cutscenes showing real-life footage run too slow (just video, audio is fine), one cutscene with real-life footage leads to video and audio bugs (the cutscene with Liquid explaining the Gulf War Syndrom) hack-settings used: Skip EFB-Access=off, ignore format changes=on, EFB-Copies=RAM+activate cache, External Frame Buffer=real Boltek
4.0-5935 Windows 7 AMD FX-8350 @ 4.0GHz NVIDIA GeForce GTX 750 Near Flawless emulation. 60FPS at 4x Native. Use configs above to eliminate any problems with the emulation. Combatheros
4.0-5935 Windows 7 AMD Phenom II 965 @ 3.4GHz NVIDIA GeForce GTX 760 2GB Near perfect. OpenGL Backend, 60FPS 1920x1080 3x Native. Anti-Aliasing + Anisotropic Filtering. Store EFB Copies to Texture Only (Store EFB Copies to RAM caused Codec Green Screen for me) Audio = DSP LLE recompiler. Everything else Default. BaKoFFiCeR
