zxthehedgehog Posted August 20, 2014 Share Posted August 20, 2014 If you ever used Demul, you've probably seen that it's VERY slow. However, there actually is a way to change that. Here, I give you, my guide to making DEMUL run at a half-decent speed! Enjoy! Step 1: Download the newest version of DEMUL(.582 as of this writing). Extract it to a folder. Step 2: Open Plugins and Paths. Make sure the plugins are set as follows: Video plugin: gpuDX10 Sound plugin: spuDemul(only choice) GD-ROM plugin: gdrCHD Controls plugin: padDemul(only choice) Untick Activate BBA if it is checked. If there is nothing in Roms and Bioses Paths, create the folder "roms" in the Demul folder and click Add. Navigate to the roms folder in the window that pops up and click on OK. Once done, close Plugins and Paths. Step 3: Open the Video tab in Demul. Set the Windows resolution to 640x480, and internal resolution to 1x. Tick Disable Auto Sort, Disable Opaque Modifier, and Disable Translucent Modifier. Click on OK. Step 4: Open the Sound tab. Set the Buffer size to as high as it will go, and tick Disable DSP. There you go! There may be a few issues in 1-2 games but, otherwise, I have yet to discover any problems with it. ______________________________________________________________________________ Issues (fix-related): Missing lifebars in KOF XI/ Neo-Geo Battle Coliseum, otherwise fully playable Capcom vs. SNK 1 intro missing text & cutaway from galaxy, otherwise fully playable Green lens flares in KOF XI Graphical errors in DolphinBlue, otherwise fully playable These are all related to Disable Auto Sort, and while turning it off fixes these, it also runs at 1/6 of the speed if you turn it on. Seriously, just don't use it. ________________________________________________________________________________ Issues (DEMUL-related, not related to fix) Sound bug in DolphinBlue Buggy Hikaru Emulation No sound in Hikaru Inital D won't boot (CARD R/W ERROR!) Post any questions/comments/issues in the comments, and I will update the post as needed. Link to comment Share on other sites More sharing options...
Agrajag Posted August 20, 2014 Share Posted August 20, 2014 Thanks a lot for this. I looked at Demul briefly some time ago, couldn't get it working properly, then forgot about it due to being too busy to troubleshoot it. I'll be sure to give these settings a try when I have time!

Aceisback Posted August 21, 2014 Share Posted August 21, 2014 I have been unable to get Demul to work right on my system, but your suggestions helped. Thanks! Link to comment Share on other sites More sharing options...
albert_c Posted August 21, 2014 Share Posted August 21, 2014 Word-up! The only other system that will be in my cab besides MAME is the Dreamcast for arcade action. Thanks! Link to comment Share on other sites More sharing options...

Seriously, just don't use it. While your guide is appreciated, honestly the best solution to get good speed but more importantly Correct emulation by leaving autosort on and using the DX11 gpu plugin, is to get a video card from the specs of about a GTX 650Ti and up, which does the trick for my cab with all Demul arcade titles. Iirc auto sort affects ALOT more games than you listed, I went through every Atomiswave and Naomi game for cab, and it really needs to be enabled. It's just slow because the emu is just a mess IMO and really unbalanced/unoptimized. The way the devs are developing this emu right now is heavily influenced by GPU power.

dark13 Posted August 21, 2014 Share Posted August 21, 2014 I agree with tnrz, dx11 is usually faster. Dx11 is usually faster than dx10 even in windows games. Moreover disabling opaque modifier and translucent modifier will make 3d graphic worse. This emulator really likes hi-end videocards, demul is the only emulator to got a speed bump when i upgraded from 9800gtx+ to 660gtx. Sadly there's no "magic wand" for demul/pcsx2/dolphin, you can gain some fps tweaking here and there but you really need an overclocked cpu and a good videocard -.- Ah... they even dropped x64 build. X64 usually is 30% faster than x86 code, just compare x86 mame or dolphin vs x64 builds... Link to comment Share on other sites More sharing options...
Agrajag Posted August 22, 2014 Share Posted August 22, 2014 Hmm, I have an overclocked i5 and overclocked 660ti so I obviously needed to spend more time tweaking the settings before abandoning it! Another job for the weekend... Link to comment Share on other sites More sharing options...

So that should show you what you are up against. Meanwhile my CPU power is only around 15-20%. The most demanding game I have encountered on my arcade cabinet is Wild Riders, which is Naomi 2. There is not a single arcade rom on my htpc so I have not thrown that game at my 770. But like I said, even a 780 ti would probably get stutter if trying to go above 2x. It once again boils down to poor optimization. Dark13, yea I know what happened to that x64 build that was supposed to come out? So much for that. But ya know the Demul devs just do as they please, because they have everyone by the balls because it's closed source. Alls they do all year is post pictures of new games they get to boot, but how about fixing game breaking bugs that have been in the emu for YEARS like the music stopping problem in Dolphin Blue, or the game crash in Initial D? I would bet money that with the new release that comes those bugs will still not be fixed. Link to comment Share on other sites More sharing options...
HazzardActual Posted August 22, 2014 Share Posted August 22, 2014 is anyone else randomly loosing sprite layers in Atomiswave mode on demul? On blue dolphin and a few other games entire parts of the level are either bright green or see through. Link to comment Share on other sites More sharing options...

Make sure you are NOT disabling list sorting and are not disabling any of the other video options either. That did not happen to me when I was using the latest Demul for Atomiswave. Try getting your hands on the Atomiswave to Naomi conversions and run Dolphin Blue on Makaron. That's what I did for Dolphin Blue until they get that nasty music bug fixed...if they ever do.

zxthehedgehog Posted August 24, 2014 Author Share Posted August 24, 2014 I would recommend the Atomiswave to Naomi conversions (done by Breaking CPS3, Google is your friend) for playing Dolphin Blue. I know this fix causes lots of bugs, but otherwise for most of us who have less-high-end systems, it should load most games with a good deal of speed. Whatever works for you may be quite different from this, but, for me, this is what works the fastest. If your specs are higher, the DX11 plugin may be a good choice. Personally, on mine, which is built for DX10, it just runs slower, but, if you have a high-class Alienware, Origin, or a custom gaming tower, you may want to try DX11. That mainly has to do for what your graphics card is made to do. It mainly is what works for you. Also, the bugs I found were mainly the bugs I found while testing the games I had. I have it mainly for arcade emulation, and will update it with bugs as I find them. Link to comment Share on other sites More sharing options...
albert_c Posted September 16, 2014 Share Posted September 16, 2014 First time ever playing with Demul. So far it is running MVC2 like crap. Can anyone recommend some settings? Here are my system specs: Dell L720x Laptop Nvidia GT555M GPU 8GB RAM Windows 7 64-bit Messed around with versions 0.582, 0.57, and 0.56, with and without the DX10 or 11 plugin enabled. Runs pretty crappy. I have yet to select different bios versions. So far not much luck. Help. Link to comment Share on other sites More sharing options...
albert_c Posted September 18, 2014 Share Posted September 18, 2014 Got Demul running decently on another machine which has lower specs than my laptop: Dell Precision 390 Intel Core 2 Duo 6600 @2.40GHz 4GB DDR2 Gefore GTS450 Windows 7 Home Premium 64-bit Most of the settings in the first post produced mixed results. I found better results with the DX11 plugin, without disabling Auto Sort; Disable Opaque Modifier; and Translucent Modifier. As this machine is lower spec'ed than my laptop and is going to eventually wind up in a cab or a dedicated machine for arcade gaming, this leads me to suspect that Demul is very peculiar with it's setup. I tried running Makaron on my laptop with worse results than Demul. I suspect Makaron may run better on this dedicated machine. Weird. Link to comment Share on other sites More sharing options...
urbangangsta101 Posted September 18, 2014 Share Posted September 18, 2014 I'm currently working on a Demul complete per-game control setup for the Xbox 360 Controller.

Atomiswave is complete, Naomi in progress...Will share when i'm finished... Quick question: For Atomiswave and NAOMI, are you simply pointing your HLHQ to your MAME roms (if so, what MAME set do you have?) or have you downloaded a different set of roms spefically for Demul?

albert_c Posted September 18, 2014 Share Posted September 18, 2014 Ah, cool. Saw an older thread where users with MAME 1.51 were simply pointing Demul to the MAME>roms folder and running Demul without issue. I got MAME 1.54 and a few MAME roms work, most don't.
