WiFi not emulated and not supported!!
We won't make a 3DS/2DS emulator.

#1 Re: Support » Save got corrupted now DEsmume now i get "Data could not be accessed." » 2017-11-12 01:02:37

probably won't happen. use desmume in retroarch, maybe they have such a feature. thanks for lending me your confidence that it's user error. with that and the confidence I already had, I can be positive. Despite the 1000s of times it happens to pokemon gamers, I get useful information only zero times, so usually I can only guess.

It might speed up whenever we add a texture database

#3 Re: Support » Save got corrupted now DEsmume now i get "Data could not be accessed." » 2017-11-11 00:42:40

No. corruption is an irreversible process. Make backups of your .dsv files if you're heavily invested in them.

#4 Re: Support » what is the bottle neck with desmume at larger resolutions and opengl? » 2017-11-06 16:30:47

haven't we been over this before? desmume does a lot of processing on the CPU still.

#5 Re: Compatibility » golden sun dark dawn djinn bug » 2017-11-03 22:53:20

weird, this is 2d, not 3d. and this is even the kind of thing we've bugfixed since 0.9.11

#6 Re: Compatibility » golden sun dark dawn djinn bug » 2017-11-03 22:08:34

post a your .dsv file saved at a point where I can investigate this readily

#7 Re: Compatibility » golden sun dark dawn djinn bug » 2017-11-03 17:47:11

post a screenshot and if possible find a video of this scene on hardware on youtube. i really doubt this mismatches the hardware. it's almost impossible for me to imagine how something accidentally gets transparent.

#8 Re: Compatibility » golden sun dark dawn djinn bug » 2017-11-03 15:08:49

change the 3d renderer or use a newer nightly build

#9 Re: Support » Troubles with Save states in Pokemon Diamond » 2017-11-03 02:55:52

no. You ignored the warning the game showed you that said this would be impossible.

#11 Re: Support » GameInfo reading out of buffer » 2017-10-29 18:47:15

there is no wisdom. there is no reason.

ideally you would figure out what correct emulation should do, and fix it to do that instead of exit.

#12 Re: Support » GameInfo reading out of buffer » 2017-10-28 22:39:53

Check one:
[ ]  I understand that errors have been inconsistently handled by dumping registers, or trapping with the GDB server embedded in the emulator, but I am surprised that still more errors have been inconsistently handled in a 3rd way by terminating the emulator

#13 Re: Support » Pokemon Platinum black pixels appear randomly on top screen. » 2017-10-24 16:28:22

If you had "Read the FAQ before posting" you would have probably seen to try changing the 3d renderer, whereupon you would have discovered that the black specks are reduced. There's nothing you can do to get rid of them entirely.

DeSmuME_git#73b5074_x64.exe on i7-4790K (but I just remembered, I have overclocked so it runs all cores at 4.7GHZ instead of 4.00GHZ with one core boost to 4.4GHZ... so my 75% figure earlier was not accurate.. should be more like 70% or something, I'm not sure).

1x - 255fps
2x - 210fps (you can see, it's truly gpu bound immediately. forget what you think you know about how graphically intensive ds games are. can you understand a child speaking simple 4 year old sentences in dutch? no? it's a different language, it does not matter how simple the sentences are)
3x - 160fps (I think I heard a fan getting louder)
4x - 133fps (note, I am NOT making the window larger. why make the test more complex?)
5x - 98fps (at this level, some architectural problems in desmume make the framerate less smooth than it should appear. you and I are still evaluating the FPS indicator though)
6x - 77fps
7x - 61fps

#16 Re: Support » zeromus i am not using magnification filters nor do i intend to » 2017-10-17 07:56:56

That's ridiculous. People routinely max out their GPUs going to absurd 4k resolutions running emulators in high resolution. Your analysis doesn't make any sense. You think you don't get "slowdowns" because you happen to stay above 60fps. You'd get "slowdowns" if you ran it unthrottled to do an actual benchmark. "Slowdown" is not an appropriate term in this case. You write the FPS you get. Either it matches expectations or it doesn't.

Desmume performs some processing in software, because it's not entirely a 3d system. Increasing the resolution increases the GPU load as well as the CPU load. Your CPU is kind of junky

By the way, to properly benchmark mario kart, do a time trial and sit at the starting line.

I'm getting about 250fps now after I zapped my ini file and tuned everything. Since this shouldnt be loading the GPU at all, you should be getting about 75% as much as me, or ~185.

Another good benchmark for pure CPU is the yoshi touch& go title screen (you can let it run into the tutorial scene, it's the same performance basically. This is actually 100% CPU bound. I get 220. You should get about 165. If you get substantially less than that you DO have rogue processes stealing cpu or you DO have broken video or audio drivers and desmume can't even output its sound and video without getting snagged, or you DO NOT have your power performance profile configured correctly.

#17 Re: Support » zeromus i am not using magnification filters nor do i intend to » 2017-10-16 23:27:05

no, I don't think ps2 emulation might need more power on the same graphics API.
"no performance loss on resolution scaling" doesn't mean anything except that the emulation is CPU bound.
Perhaps yours is CPU bound because you havent followed all our speedup tips yet, including enabling the dynamic recompiler.

#18 Re: Support » zeromus i am not using magnification filters nor do i intend to » 2017-10-16 23:04:57

well then all you have left to do is upgrade and downgrade your gpu drivers and remove streaming garbageware. That it's "the best laptop" doesn't mean anything to anybody but you. Sometimes the best isn't good enough. Though I'm sure it is in this case if you can find the faulty software on your system.

#19 Re: Support » zeromus i am not using magnification filters nor do i intend to » 2017-10-16 22:57:54

for comparison i get 150fps with the fastest settings for me (ddraw HW display method), on a "GeForce GTX 750 Ti/PCIe/SSE2" at 1x resolution on my workstation, while the CPU doesn't even get warm.  I don't know how much it being weak laptop hardware can account for, but probably not that much.

You should delete your desmume.ini file in case youve broken something in it, and upgrade and downgrade your gpu drivers

#20 Re: Support » zeromus i am not using magnification filters nor do i intend to » 2017-10-16 22:44:24

Then your system is hosed. 70fps at 1x is pathetic. About the only explanation for that is intel gpu involvement. You need 2 new methods for confirming that your nvidia gpu is working. For instance, look at what prints in the console log when desmume starts up with 'driver info"  (edit: you should probably gather ALL that information in the log). think of something else, too.

Blow dust out of your fans

upgrade or downgrade your GPU drivers

#21 Re: Support » zeromus i am not using magnification filters nor do i intend to » 2017-10-16 22:38:13

what unthrottled fps do you get in-game at 1x resolution? Also try disabling any streaming garbageware youre running. Also, I bet you've actually failed at choosing the nvidia GPU. It's hard to believe there's no difference between them. Double and triple check with every method you can think of for checking.

#22 Re: Support » zeromus i am not using magnification filters nor do i intend to » 2017-10-16 22:29:47

Then I predict you havent actually enabled the nvidia gpu for desmume. Try forcing the nvidia gpu for everything to make sure that it takes effect for desmume, and then use the opengl renderer

I don't really care what your CPU usage is. You don't write literate reports consisting of which settings you're using, what your unthrottled FPS is -- and what the CPU usage is. That's the only way it could be interesting.

But you should really give up your delusion that desmume should use 100% of your CPU. It won't, if it's bottlenecked by your GPU.

#23 Re: Support » zeromus i am not using magnification filters nor do i intend to » 2017-10-16 22:26:06

If the fps is over 100, then you don't have performance issues.  If it seems like you have performance issues still, then you need to blow the dust out of your fans, or change config > display method. Or youve accidentally selected a number in the frame skip menu.

#24 Re: Support » zeromus i am not using magnification filters nor do i intend to » 2017-10-16 22:17:40

Your estimates of what your system should be capable of are incorrect. You're getting just about the results I'd expect from someone who hasn't read the faq and followed the advice to try changing the 3d renderer from softrasterizer to opengl, or to change config > display method to different settings.

You haven't made a literate post about performance unless you've disabled config > frame skip > limit framerate and reported the results for various combinations of settings.

#25 Re: Support » please look at my problem this time.(performance issues with i5 7300h) » 2017-10-16 21:43:16

Your estimates of what your system should be capable of are incorrect.
There are no "shaders". Where did the menu telling you that you were picking a shader? You were picking a software implemented magnification filter. they kill performance.
Since I've explained this already, but you didn't understand it, I guess you have a hard time reading, so you also didn't understand the bit about the sticky, which meant for you to find this: http://wiki.desmume.org/index.php?title … oo_slow.21
