Not Implemented Opcodes - Spawn in the Demon's Hand #42

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?

1: Run Nulldc
2: Load Spawn in the Demon Hand

What is the expected output? What do you see instead?
Actually, you should see the game past the VMU Screen, instead, after
saving a block in the VMU, it freezes saying lot of non-implemented Opcodes.

What version of the product are you using? What build? What plugins?
Right now, Im using nulldc r22.

I use the following plugins:

PowerVR Plugin: nulldc PowerVR Direct3D HAL [May 13 2010]
GDRom Plugin: Image Reader Plugin by drk||Raziel and Gigaherz [May 13 2010]
AICA Plugin: nulldc AICA [May 13 2010]
ARM7 Plugin: VBA ARM Cpu Sound Core [May 13 2010]
Maple Plugin(s): PuruPuru Imput Plugin v0.1 by Falcon4Ever [May 13 2010]
Ext.Device Plugin: nullExtDev [May 13 2010]

On what kind of system?
My system specifications are as follows:

Operating System: Windows 7 x86
CPU: Intel Dual Core E2140 Oc'ed to 2.8ghz
Video Card: ATi Radeon HD4760 512mb
Sound Card: Realtek AC97 (Onboard)

Please provide any additional information below:
There is not much to say about the configs...since it was a missing opcode.

I thought Spawn was working already.

GDI or CDI ? 
Does it work with Dynarec disabled?

GoogleCodeExporter commented 9 years ago 
for example, I have CDI...

And I cant start this game in first time... its just freezes with message about
memory card--- but on second time it can be works.

Normally it can starts in first time only then I disable dynarec!

dynarec? where in options is this?

To change the dynarec optinos open the Nulldc emulator, Options, PowerVR then 
you have several options, one of which is the dynarec.

Use the new Nulldc r50 available here, in the section Downloads. Some issues 
associated with dynarec might have been fixed. Try it!!

 telmo.quintas! Spawn is not fixed yet!(r50) ---> In first loading when we must create savefile its just freezes on VMU screen! It happens if Dynarec Enable. Normal boot in first time possible only if Dynarec is disable!!!

If you feel interest look at my report with screenshots in issue 52 (Comment 31 
 by N2008eo...@rambler.ru)

I saw your report with screenshots in issue 52. It was very detailed ;) . First 
boot time of Spwawn in the Demon's Hand is only possible with Dynarec disabled 
in the PowerVR options. From what I saw it's a not implemented opcode.

I have to disable Dynarec each time I play Spawn, not just on the first play 
when creating a save - I get the missing opcodes errors whether I'm saving or 
loading.

Hm, i also have that problem in r75. I found a bad working fix: just disable 
dynarec before launching the game, but then enable it during Capcom logo video. 
It is way to play. However, it also could give some errors time to time and it 
has some freezing while playing this game. Please fix this problem in r76. It 
really disappoints.

proletar666 - Yes, I reenable Dynarec after the save/load screen. Does the 
opening FMV also stutter for you now? I don't remember that either in earlier 
versions.

Oh, wait a minute, it is a mistake. It is not FMV video. It is SFD video. Just 
extracted data from gdi and then checked it.

Took a look of this issue yesterday. Very strange indeed.

It looks like a multi-threading issue at first, but it does not seem to 
actually be.

After tracing for a bit the problem seems to be related to the GD-ROM 
hack-sync. Sometimes it "works". Other times data on RAM end up wrong and, 
well, it dies.

Funny part is that the end result can vary (to the point it works, it resets 
the system, it just encounters invalid opcodes, younameit).

I can add a GD-ROM DMA delay. This will probably fix it, along with other 
possible related issues.
The problem is, does it worth it? It will slow emulation down (as the maple and 
SPU DMA delays did). DMAs need a new implementation and patching around the 
issue... well, it's not such a good idea.

Tested with nullDC 104 r136.

Start game first time with Enable Dynarec and create savedata on VMU

Game encounters invalid opcodes

Exit nullDC

Open nullDC and uncheck Enable Dynarec in Options -> nullDC Settings

Select normal boot and load CDI

Tested and working fine
