Metal Gear Solid: The Twin Snakes

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.

Crashing
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.
