Dolphin Questions!

Hey you all,

I have 3 questions regarding Dolphin on Android!
I hope some of you can answer me these:


Is the Pixel Aspect Ratio / VI Scaling fix implemented in the Android Version?
(This was implemented in the dolphin desktop version way back in 2015 So I'm just wondering if it's also in the Android build)


Why is android kinda treated as the black sheep?
I know driver issues on Android suck but I am running super mario sunshine at 720p flawlessly on the official Dolphin build (clock speed set to 100)

if you override and adjust the emulated CPU Clock Speed to 60& or 50% does that result in playing games half the framerate?
I've seen a reddit post and that's what a guy claimed. Is that true? or is it just missinformation and  complete  bs?


Thank you for your time reading this!

Yes, it was added to the Android builds at the same time.

Not sure exactly what you mean by treated as the black sheep, but... While the drivers have gotten significantly better in the last few years, there are still problems (e.g. EFB copies to RAM on Adreno). And then there's also the quite different problem that very few developers are working on Android specifics.

The framerate can get lower when you lower the emulated CPU clock speed – either with a corresponding reduction in game speed or without (it depends on the game) – but it's not as simple as "50% of the clock speed means 50% of the framerate". The results are different for each game, so you have to try it out to know what happens for a certain game.

thanks for the quick answers! good to know that the Android version has it. So it automatically adjust the perfect aspect ratio like in the desktops builds?

With blacksheep I meant that people in this forum kinda have this view? I think? I have seen a few posts (regarding mmj and the official build.)
I'm new to emulating with Dolphin so for what is the option to lower or raise emulated clock speed?  And with the 50% clock speed=50% is bullcrap ok

would you recommend using the unnofficial mmj build?

We don't provide support for any unofficial fork (that's not something exclusive to MMJ). We do, however, allow these forks to have a single thread (which is the case for both MMJ and Ishiiruka, for example) where we direct people asking for help with these forks, so they can ask support directly from their authors.

For me personally, the negative view you might notice comes down to our Android user base being super toxic (from all OSes we support, I'd say it's the most toxic of all). People refuse to accept most smartphones still aren't good enough for running Dolphin at fullspeed and without hacks (e.g. emulated CPU clock override) and instead go attacking the staff and the emulator itself. Then, when a fork like MMJ surfaces (which is essentially vanila Dolphin + tons of hacks to overcome the mobile GPU driver issues at cost of stability) this same user base starts deifying the fork authors and completely bashing the hard work the "official" team had to do in all these years before fork authors could have something to use as base to add their hacks and make these custom versions.

And let me not get into the flame war we got dragged in when we temporarily locked MMJ forum thread because it was violating our GPLv2+ license by not providing the source code used to build the APKs they were providing...

The clocksspeed = framerate is only really true of games that have variable framerates. The majority of console games are actually coded to run at specific framerates, since unlike a PC the developers know the exact hardware (or sometimes small sub set of hardware) that every copy of the game will be run on.

Some games just flat out break when run at a different clockspeed then it is expecting. Some run mostly fine with some issues here and there. There are even a few that run perfect at lower clockspeeds, though I am not sure if those game are any easier on the host system when run at a lower emulated system clock.

The only real issue I see with android is people not quite getting that a $1,000 phone generally does not equal the performance of a $400 PC, due to a variety of reasons (not the least of which being no one wants a 65W space heater in their pockets with 10 minuets of battery life as their phone... probably). Also forum users getting annoyed and a little snippy with people because they have answered the same questions of why insert X phone does not play GC\Wii games as well as someone thinks it should. Dolphin for android is interesting and definitely something I like to mess around with and see exactly what works and what does not, since with a reasonably good PC Dolphin just works. Coming from a time when I used to have to run 3 different PS1 emulators with multiple versions of each to get different parts of my collection to work, I kinda miss the messier side of emulation.
