In other words, many of your favorite games from Gamecube and Wii can not be played easily.In addition to the lack of full compatibility, Dolphin Emulator allows you to configure every aspect of the program. You can turn on the ‘dual core’ option for devices that support it, and even connect a controller on the device and configure it as well.Dolphin Emulator is a very powerful emulator, thanks to which you can play Gamecube and Wii video games on your Android. Dolphin is the primary emulator for GameCube and Wii games.Plenty of GameCube games have some pretty creative solutions that rely on rather obscure behaviors of the processor which are more expensive to emulate. That pegs the Wii processor at roughly 67% more powerful than the GameCube! That means that Dolphin's CPU thread should be much more stressed out by Wii games, right? Not necessarily, in fact the Wii's extra power can actually play out in Dolphin's favor!The GameCube's slower processor may have proven to be a bottleneck for many developers. The biggest difference between the two is that the GameCube's Gekko PowerPC Processor, a modified PPC750CXe, is only 486MHz while the Wii Broadway Power PC Processor, a close to stock PPC750CL, is 729MHz. "Gekko" By Baz1521 - ja.wikipedia.org, CC BY-SA 3.0The GameCube and Wii have very similar CPUs.GPU Emulation - Flipper V.S. Overall though, the Wii's stronger processor doesn't do much to make emulation harder. Ambitious developers could get everything and more out of the Wii that they could out of the GameCube. On that note, many Wii games actually are easier on Dolphin thanks to the processor being stronger.That is not to say that a Wii game can't be more demanding than a GameCube games, though.
Even then, if you only care about performance, High Level Emulation (HLE) trivializes the performance impact of emulating the DSP in modern Dolphin. Sound Emulation - The GameCube and Wii DSPs ¶There isn't that much to say here except for a few minor differences. While there may be some extreme examples here and there of a game taking advantage of the Wii's extra GPU power to make Dolphin stumble, the bump in clock for the Wii GPU doesn't make a major difference in most cases. The fact that Hollywood can draw more pixels and render more triangles is of very little concern to Dolphin, as the host GPU in a modern PC mixed with the CPU Vertex Loader JIT is more than enough to handle it. It features a 243MHz Fixed-Function GPU (Hollywood) compared to a nearly identical except clockrate 162MHz GPU (Flipper.)The main bottleneck for emulating their GPUs comes from Dolphin having to flush the pipeline cache in situations when Flipper and Hollywood's GPUs didn't! They were extremely robust and could handle tons of state changes without flushing. Gamecube Emulator Twilight Princess Upgrade In RAMARAM Flips The Script! ¶While ARAM could be used for audio processing, some ambitious developers thought it would be a waste to leave that 16MB of RAM sitting there just for audio when they only have 24MB of regular RAM. This is the first hardware change that greatly impacts emulation. The Wii dropped this ARAM in favor of adding a 64MB MEM2 region that games could directly map without having to use paging. Both consoles feature a 24MB MEM1 region that is more or less identical for emulation purposes.The main change is that the GameCube had 16MB of slower A(udio)RAM that wasn't directly mappable to the processor. Wii MEM2 ¶It shouldn't be any surprise that the Wii also saw an upgrade in RAM over the GameCube. RAM Watch - GameCube ARAM V.S. While there are a few custom implementations, a majority of games that make use of the ARAM as virtual memory use Nintendo's libraries.Dolphin didn't actually receive its initial implementation of full MMU emulation until July of 2010, so instead of leaving these games completely broken, a more evil solution was devised. This behavior became much more widespread when Nintendo started providing a library to help developers page memory into and out of ARAM. Some of the most demanding games on the GameCube resorted to this to get an edge over their competition by essentially having an extra 16MB of virtual memory to work with.Click the image to go to our blog article that deals with MMU emulation in more detail.The early libraries provided by Nintendo didn't provide for using the ARAM as virtual memory, so most of the early games (except for Rogue Squadron II, of course) didn't use the ARAM for virtual memory. Then their specially programmed exception handler would map in memory from the ARAM into the page they were trying to access while paging something else out (which if accessed later on, could be paged back in!) When the exception handler returned program execution back to where it was, the fetch/load/store would go through as if the memory was mapped all along. A few notable examples include, but are not limited to: Star Wars: Rogue Squadron 2, Star Wars: Rogue Squadron 3, Star Wars: The Clone Wars, and Spider-Man 2. Full MMU was incredibly slow and left most of these games nearly unplayable despite the emulator finally being able to boot them. By emulating memchecks and the rest of the process of paging data in and out of ARAM, Dolphin could finally boot those games. For them, Full MMU was devised. This bypassed the whole song and dance of memchecks, the exception handler, and paging data in and out of the ARAM!This didn't quite work for games with custom solutions. By simply marking those regions of memory as valid, the games would be able to read from and write to virtual memory without issues. This means that Dolphin doesn't have to worry about MMU emulation in general. They're still extremely demanding, but, many of them can run on modern hardware without slowdown.Wii games don't have to do any of this - they have full access to the 64MB of MEM2. In recent years, many, many optimizations to the JIT have made some Full MMU titles run fairly well. Instead it has to enable expensive memchecks and make sure that memory is valid before letting the game access it.

Full MMU emulation is just one of many, but, here are some of the other common behaviors that affect emulator performance. This is because of the various features these games require. Other Demanding Behaviors ¶Some games are very lightweight to emulate while others are problematic. Those games will be covered in another article as they seem to particular target Dolphin's weaknesses and thus some of their behaviors doesn't actually make sense for the source hardware. Dolphin has to copy the memory across PCIe, send everything to the GPU, and then wait for it to finish doing its work before continuing. This is much slower on modern computers than it is on the GameCube and Wii for several reasons, including the fact that the GameCube/Wii CPU and GPU share RAM. With Store EFB/XFB Copies to RAM, we faithfully copy the framebuffer off of the host GPU and into RAM. This works for most effects as long as the GameCube/Wii CPU doesn't need to use it for anything in particular. In the case of The Legend of Zelda: Twilight Princess, the performance difference is so huge that maximum speed can be doubled just by using Vulkan in some areas. This is because Vulkan has a single immutable pipeline switch and can be potentially cut down to just three API calls, compared to tens in OpenGL. The one thing to note is that Vulkan helps a lot in draw call bottlenecked situations thanks to more efficient handling of draw calls and far fewer API calls.
