nullDC 1.0.0 beta 1.6 [07/11/2007 update]

[LensLarque]

Well, you can also patch the image with Pal Patcher or Adrenalin Patcher (I recommend the first one) and make it boot in 60Hz whatever the bios region is.

??? No, they do run at 60fps... Unless the games I test do not use the BIOS to determine that.

[drkIIRaziel]

Many games just use the settings bios seted up.That includes Soul Calibur , MVSC2 and RECV.

Shenmue running fluently in 1920x1200!!! with full sound and (except from the unreadable diary text on later pages and some single transparent hairs) almost perfect graphics!! WOW!

From what I know, the behaviour on a real Dreamcast is that most games run at 60Hz NTSC on a NTSC console, wouldn't be nice if they didn't

A few PAL games give you a choice between 50Hz and 60Hz even on a NTSC console or a emulator trying to play a PAL game with a NTSC bios. One such game is the PAL Soul Calibur on a NTSC console.

With nullDC beta 1.5 & now beta 1.6, I've noticed that NTSC games that required patching to NTSC with PAL Patcher (attached) so they were forced to run in NTSC on a PAL console actually run in PAL video mode even with an NTSC bios in nullDC so this is unusual behaviour from nullDC and one which did not exhibit itself in beta 1.

Beta 1 did not emulate the SPG settings, it just forced 60 fps all the time.Its not the bios that makes the difference but the flash file, actualy =p.With correct files, nullDC runs on NTSC mode properly (or used to, when i tried it).

[Linktothepast]

drkIIRaziel are there any thoughts at all of implementing "true vmu" emulation, and not just a memory card (even in the distant future)? Would it slow things down a lot and doesn't worth it?

Its (very) easy to do .I just need to work at it

[Juzbrig]

I have a quick question for drkIIRaziel too if you don't mind:
Do you plan in the nearest future to add 'sync' into chankast's AICA, or upgrade nullAICA so it won't clicks, cracks etc. or plays in loops or incorrect some fragments (eg. some fmv's) in severals games ?
Because I don't know if I should play some games I really want to play, but the sound is bad, or wait few weeks and it will be fixed.

Second little question:
Why 'hardware mixing' in nullAICA is producing worse quality then without this option ? The logic says that is should be oposite...

[drkIIRaziel]

HArdware mixing is problematic on directsound, dont ask me why .Microsoft plans to drop it totaly (they did so on x64 oses and on all Vista vers).

The way chanka aica works makes it harder to limit the speed.Thats why its not implemented.It may be sometime, duno ...

Excellent work with the emulator, the games you see every better, I can not wait to see the next version

I can not stop playing doa2, this is the best emulator of dreamcast ¡¡

I have trouble booting any game! Tied both MDS and CDI. Here's what I get


Also the Joystick plugin doesn't seem to work for me. I tried to configure my controller though it, but it didn't accept any commands from it. So I wen back to Joy2Key.

Edit: Strange got it to work. Just red a couple of pages back how to make the joystick plugin work... And with it foxed the emulator booted the games... WTF? Anyhow I just played Soul Calibur for a few minutes but I see lots of improvements, terrains and menus. Great job guys, thanx
Esc doesn't work for exiting the Emu, gotta use Alt+F4 now

I gotta problem!! I can't even open up the NullDC exe. After I extract it and try to open it up and gives me an error "This application has failed to because the application configuration is incorrect". Can anyone help me with this problem plz!!!

[drkIIRaziel]

Try to folow the readme instructions -.-.

[fillstrup]

I had the error of d3dx9_35.dll on nulldc 1.0.0 beta 1.6 and i download only the d3dx9_35 library and put in windows/system32/ and fix it
Amazing emulator thanks!!! (sorry for my poor english).

[zeox]

You don't need to put it in windows\system32\ (who knowsm it might mess up something). You can simply put it in the nullDC dir.

Emulator is REALLY coming along beautifully!

Record of Lodoss war is still unplayable (Using DynaRec, it's 100% all the time - until a fight, where if you kill an enemy, the screen freezes. Disabling DynaRec fixes that, but the game runs around 12fps)

Shenmue works perfectly, but has a few sound issues using ElsemiAICA. It's full speed with no graphical glitches (except the noted ones from the Diary) using these settings;

Textures: Versioned.
Sort: Triangle.
Modifier: Normal

Dead or Alive 2 is.. hmm. Still not 100% and has some weird slowdown glitches at the start/end of each fight.

Tech Romancer is flawless. Sound, graphics, speed.

Zombie Revenge is flawless. Sound, graphics, speed.

Resident Evil 3 has massive graphical glitches, rendering it unplayable. Perfect speed and sound though.

Soul Calibur is flawless. Sound, graphics, speed.

D2 is nigh-flawless. Graphics and speed are perfect, sound is scratchy ... no buffer size changing fixes it. ChankastAICA has perfect sound, but with no sync it runs too fast.

I'm about to test Jet Grind Radio. I love the gamepad support, so far it's working flawlessly. The Sync options for Elsemi/nullAICA plugins are not only wonderful, but also essential (playing Soul Calibur @ 160fps is less than fun when you use the ChankastAICA) and I love the nice touch you've done with the BIOS, having the emulator read the BIOS to set the speed/region. It's good because I have my own UK dumped BIOS, but launching NTSC games changes the system over. Very well done!

Ok, Jet Grind Radio is soooooo close to being perfect. Full speed, perfect sound -- but a few graphical glitches (mainly shadows and missing/deforming textures) That was with NullPVR, I'll try Chankast's now.

Here's the NullPVR plugin.


The same scene with ChankastPVR. Notice the missing shadows? Well that's preferable to the rest - because with the shadows there, the screen and textures deform badly.

The fights seem fine to me. The only place I see weirdness is during the opening movie, but even then it's far, far less weird than it used to be.

For me the opening movie is all screwy. Just the initial flyover has all kinds of glitches. It actually got alot worse since 1.0. There are also problems with the shadowing, though I don't know if there's a setting to correct it. Either I get shadows with missing pieces, or huge overblown shadows.

NullDC came in really, really handy a couple of weeks ago when I was stuck at the airport for six hours. Laptop, gamepad, and the only power plug in John Wayne airport and I was good to go, though I forgot just how rough Soul Calibur was on my hands.

Well the game is fine, graphical content and all -- it just suffers from HORRENDOUS hitching at the start/end of the fight. Seems a few others on here are having the same issue with various other games. Not sure of a remedy yet >_<

I'll have a play around with it tonight, see if I can fix it. Running off a CDI image on a SATA2 HDD, so it's most definitely not a loading issue. Weird. Other than the initial hitching, the game is flawless, running at 30/60 (NTSC rip)

As far as Soul Calibur, it's perfect. I've seen no issues whatsoever, not with the opening movie, not with the game or graphics or speed. Damn man, sorry to hear about your issues :-\

-=Edit=-

Ok. Wow. What the hell? Hmm. Ok.

I just reloaded DoA2 and tried it again. Flawless! NO stuttering or hitching at the start/end of the fight! That's just plain, outright, weird!
