Notable Removed Features and Support

(This is a work in progress that will be made into a proper wiki page at some point. It exists to record features Dolphin has removed, why they were removed, and when was the last version they were in Dolphin, in order to aid anyone who wants to explore an old feature for whatever reason. Feel free to use my discussion for any suggestions or help you'd like to give! Also it is not sorted in any particular order just yet, I need to figure out what order I want it to be in by default. For now I'm just focused on getting data in my spare time.)

Problems

• tables are different sizes, width=100% appears to do nothing
• cannot sort (removed sortable as it didn't work correctly with Dolphin versions)

This is a list of notable features and support that Dolphin has dropped. It for those who want to revisit and explore interesting features that we have moved on from. Do not use these old features if you only want speed - the latest development or beta builds will always be faster on modern hardware.

Features

Major Features

Feature	Introduction Version	Final Version	Removal Version	Reason for Removal	Notes
Xaudio2 Audio Backend	r6371 (2.0-987)	5.0-10947	5.0-10950	Progress Report Oct 2019
WX GUI	Megacommit	5.0-8277	5.0-8279	Dolphin Blog - The Legend of Dolphin: A Lens Between Worlds and Progress Report June 2018	In the Megacommit, Dolphin used a mixture of wxwidgets for the main GUI and W32 for some plugins. W32 was slowly removed over time around 2.0 1, and was completely removed by the unification of GFX plugin interfaces in r6422 (2.0-1038).
Triforce AM Baseboard	r4437 (1.0-4437)	5.0-412	5.0-414	Progress Report August 2016	The first step of a Triforce implementation that never materialized. It never actually did much. To explore Triforce emulation, try the old Triforce Branch.
32-bit ARM Support + ARMv7 Support	3.5-476	4.0-6674	4.0-6676	Progress Report June 2015	First Android merge was 3.5-1243, but the ARM JIT was in Dolphin well before.
Dsound Audio Backend	ALPHA	4.0-2715	4.0-2717	Progress Report Aug 2014
32-bit x86 Support	ALPHA	4.0-1409	NA	Dolphin Blog - Obituary for 32-bit	Removed from Dolphin's build system and officially unsupported by the blog post. However there is no explicit removal commit - the 32-bit parts of the x86 JIT were slowly cleaned out over time. Notable cleanup commits are 4.0-1959 and 4.0-2612.
D3D9 Graphics Backend	ALPHA	4.0-146	4.0-155	Dolphin Blog - D3D9: Why It's Not a Part of Dolphin's Future
OpenGL 2 Support	ALPHA	4.0-26	4.0-27	Making way for tev_fixes_new, removing hacks	Explicitly OpenGL 2.1, set as our min version by 3.5-1203. Before that is complicated.

Minor Features

Feature	Introduction Version	Final Version	Removal Version	Reason for Removal	Notes
ASCII Art Shader	3.5-1025	5.0-12879	5.0-12881	Progress Report Oct 2020	Original commit was in the GLSL branch, merged into Dolphin with the GLSL merger.
3D Vision	r6347 (2.0-963)	5.0-10943	5.0-10945	Progress Report Aug and Sept 2019	The first implementation was removed with D3D9 in 4.0-155. However a new implementation was made in 4.0-4643.
Fractional Internal Resolution	Alpha	5.0-5094	5.0-5097	Progress Report July and Aug 2017	Can corrupt saves in some cases, revisit with caution. Originally Dolphin just presented typical PC game resolutions which were always fractional. However, Dolphin switched to controlling EFB Scale (Internal Resolution) after 2.0. 1 2
Frameskip	r3949 (1.0-3949)	NA	5.0-1033	Broken	Was broken long before it was removed. Even when it did work, it only worked with certain settings (such as XFB Disabled), only worked on certain games, only worked on 50 or 60FPS titles, and had minimal performance improvement if any. Possible versions to try to see it "working" would be versions before major graphics overhauls, such as tev_fixes_new (4.0-1192) or the GLSL Rewrite (3.5-1025).
Disable EFB Copies	TODO	4.0-5653	4.0-5656	No longer necessary	An extreme hack to work around Dolphin issues.
Disable Textures	r988 (1.0-988)	3.0-691	3.0-692	No longer necessary	An extreme hack to work around Dolphin issues.
Disable Lighting	r988 (1.0-988)	3.0-690	3.0-691	No longer necessary	An extreme hack to work around Dolphin issues.
