Star Wars Rogue Squadron II: Rogue Leader is an arcade-style flight action game co-developed by Factor 5 and LucasArts. The second of three games in the Rogue Squadron series, it was published by LucasArts and released as a launch title for the Nintendo GameCube. The game was praised for its amazing visuals, thanks to an impressive game engine that uses advanced GameCube features.

Similar to its predecessor, Star Wars: Rogue Squadron, Rogue Leader is a fast-paced, flight action game. Each of the game's ten levels introduces mission objectives such as search and destroy or protection that must be completed to progress to the next level. The players performance on each level is compared to three medals (bronze, silver, and gold), based on completion time, enemies killed, etc. Getting more medals results in unlocking more levels and spacecraft. Rogue Leader also has a large collection of hidden items throughout the game, from powerups, hidden ships, and hidden levels.

Because of its technical prowess, use of rare GameCube features, and plethora of hacks, Star Wars Rogue Squadron II: Rogue Leader has proven difficult for Dolphin to emulate.

Emulation Information

Shader Compilation Stuttering

Star Wars Rogue Squadron II: Rogue Leader is one of the most susceptible titles to shader compilation stuttering. The GC and Wii have no concept of shaders - everything is executed directly by the hardware without an intermediate programming language (API). Modern computers and mobile systems do not work in this way, requiring the use of shaders as an intermediary so your system's GPU can perform the tasks that the GC and Wii GPU performed directly. Shaders have to be generated though, and since GC/Wii games are not designed to create shaders ahead of time as a PC game would, when a new effect appears Dolphin has to delay the CPU thread while the GPU thread performs the compilation; a pause that does not exist on the consoles. For most games shader generation takes only a few milliseconds, but for a few demanding titles, the shaders that they generate are so large that they can result in noticeable stuttering, in severe cases pauses of over a second may occur.

Since 5.0-4869, this problem can be solved by enabling ubershaders. Changing GPU, updating GPU drivers, or updating Dolphin may invalidate the shader cache, requiring specialized shaders to be compiled again. Since 5.0-6461, Dolphin caches shader pipeline UIDs independently of the video backend and compiles them on game start. This allows cached shaders to work across different video backends, platforms, hardware configurations and even Dolphin versions as long as changes aren't made to Dolphin's actual shader pipeline. These shaders are compiled in the background when the game starts, which may cause stuttering for a short period. Enable Compile Shaders Before Starting to avoid this.


Random Hang on Mission Start

Occasionally, the game may hang upon starting missions. Unfortunately, the cause for this is unknown and the best solution is to simply close and reopen the game. This should only happen rarely.

GPU Texture Decode Crash

Leaving GPU Texture Decode enabled will cause Rogue Squadron II to crash on a fairly regular basis.

Hang on Pause or Targeting Computer

Using the targeting computer or pressing Start to bring up the menu can occasionally both result in a hang. Fixed by 4.0-4889, but broken again by 4.0-5971. This hang cannot be avoided by disabling dual core, contrary to what is stated in the official ticket: issue 8493. This is fixed on single core by 5.0-14019.

Distorted Music

Music is garbled and distorted with DSP-HLE. Use DSP-LLE to rectify this, or disable music in the game's options as a workaround. Refer issue 7228.

Fixed in 5.0-3260.


HD Texture Pack

There is a high definition texture pack for Rogue Leader on the Dolphin forums.[1].

3.0-373 Mac OS X 10.7.2 Intel Core i7-2675QM @ 2.2 GHz AMD Radeon HD 6750M Wonky, slow, and unpredictable regardless of CPU/Sound emulation setting. jedivulcan
3.0-415 Windows 7 Intel Core i5-2400 Intel HD2000 Is 100% speed all the time but the draw distance problem is too important. You can't see anything until is in front of you. Shame. If that get fix the game will work excellent at full speed. InterlinkKnight
3.0-865 Windows 8 Intel Core i5-3570K @ 3.4 GHz AMD Radeon HD 7870 Runs around 25FPS, screen flickers, throws unknown opcode 0x3d and 0x62 frequently, crashes at Star Wars logo before beginning mission, music continues to play. Whacka
3.5-1387 Windows 7 AMD FX 6350 NVIDIA GeForce GTX 560 Ti Menu screen flickers, throws unknown opcodes few seconds into first mission, audio is garbled throughout. Ship selection still runs full speed, slight screen flicker, the only bit of the game that works almost 100%, everything else is messed up. Slarlac249
3.5-1729 zfreeze branch Windows 8 AMD FX 6350 AMD Radeon HD 7850 intro/logos still really slow, audio is garbled throughout. Ship selection still runs full speed, slight screen flicker, depth issue only fixed in OGL. fast depth calculation must be disabled in game. game is still far from playable due to low FPS and broken audio. Slarlac249
4.0-2826 Windows 8.1 Intel Core i5-4670K @ 3.4 GHz NVIDIA GeForce GTX 670 same as Slarlac249 above. Attempting to run with software rendering causes multiple unknown opcode errors. Nontheist
4.0-3214 Windows 7 Intel Core i5-4570 NVIDIA GeForce GTX 770 game running at full speed but audio is mostly garbled. Very limited draw distance during the main game guybrush
4.0-3810 Windows 7 Intel Core i7-2760QM AMD Radeon HD 6990M Running with EFB to RAM external frame buffer to Virtual, audio works perfectly with LLE but the game runs slow. Need to optimize the settings, however as indicated earlier the drawing distance is too low which makes the game unplayable.
4.0-5283 Windows 8.1 Intel Core i7-4790K AMD R9 290X Running at perfect 60FPS. Using EFB to RAM w/ safe cache and LLE audio on separate thread. Graphics run better in OGL on this game and I am running at 6X IR IceStrike256
4.0-5420 Windows 8.1 Intel Core i7-4790K AMD R9 290X Running even better then last entry with the need for safe texture caching eliminated. Still need LLE Audio which causes slow downs on slower systems. Also make sure to check skip EFB access to CPU for a bit of a speed boost. This game has become extremely more accessible to more players over the last month thank you Devs!! IceStrike256
4.0-6029 Windows 8.1 Intel Core i7-4770K NVIDIA GeForce GTX 980 Runs without errors when using LLE audio and DX11 backend. Hoth intro and Vengeance on Kothlis when close to or shooting water have severe slowdowns LtRoyalShrimp
4.0-7157 Windows 10 AMD FX-8350 @ 4 GHz AMD Radeon R9 280X Works fine on missions that don't take place on planet surfaces, with occasional slowdowns. On planet surfaces (like the mission on Hoth or the one in the Maw), the framerate about halves, likely due to the sloped environments. Tested at 3xIR, 16xAF and the HD texture mod by General_Han_Solo. Alpha284
4.0-8526 Windows 10 Intel Core i7-4790K @ 4.9 GHz NVIDIA GeForce GTX 980 Ti Perfect! All slowdown has been eliminated except where present on real hardware (Y-Wing Bomb Spam). If your system doesn't have high specs don't expect these result. Tested at 6xIR D3D11 Backend, LLE Audio with HD texture pack by General_Han_Solo. IceStrike256
4.0-8750 Mac OS X 10.11.2 Intel Core i7 @ 2.6 GHz NVIDIA GeForce GT 650M No good here. Very poor, especially during cut scenes. Audio just gave static noise, with low framerate. Will try to adjust and update if I see better results. N64BOY39
5.0 Windows 10 Intel Core i7-2600K @ 3.8 GHz NVIDIA GeForce GTX 1070 Stable framerate without any special config adjustments. Audio works without issue. FPS is rather stable but framerate drops are noticeable at times. Otherwise working as expected. Unforgiven
5.0 Windows 10 Intel Core i5-3470 @ 4.0 GHz NVIDIA GeForce GTX 650 Ti Occasional short stutters during cutscenes. Constant 60FPS on space levels. Battle of Hoth and Prisons of the Maw are slightly laggy. Otherwise playable. MISSINGNO.
5.0-9 OpenSUSE Tumbleweed AMD FX-8320 AMD R9 Fury Audio is ok but laggy due to low FPS. Cutscenes and movies play very poorly varying 8-48FPS. Menu is smooth but audio lags. Star Wars text plays perfectly and in game is stable ~30FPS. MajorNyuutabaru
5.0-1615 Windows 10 Intel Core i5-3470 @ 4.0 GHz NVIDIA GeForce GTX 970 Occasional stutters disappear as a shader cache is built up. Constant 60 FPS on all stages and cutscenes at 4K. Setting XFB to Virtual fixes the twitchy pause and mission complete screens. Runs Perfectly. MISSINGNO.
5.0-5075 Windows 10 Intel Core i7-7700K NVIDIA GeForce GTX 980 Ti Edging ever so closer to perfect. Gameplay is practically perfect now thanks to Ubershaders but loads and some dialogue cause brief lag. IceStrike256
