@amidog:

with nullplugins (no compiler, etc...) it works (OS3 version) and you
can quit with the ESC key. gpupeops.dll with all features disabled
results in the "app is meditating" window

Ok, I'll try to find the time to make a debug build of gpupeops tonight.

The Warp3D plugin tries its best to render as many triangles as possible at once, but as soon as the texture and/or blending mode is changed by the game, the plugin has to flush its internal vertex cache.


It just occurred to me, do you do batching? That is, do you sort triangles by texture, or do you output triangles as they come?

Color scaling? What are you doing there?

@Rogue

As long as the game doesn't change the texture or blending mode used, I put the triangles in a vertex cache, which I flush when the texture or blending mode is changed. The PSX has a small texture cache, meaning it's a big advantage to render many triangles using the same texture at once, so I assume that's what most games do.

About color scaling. The PSX modulate does TextureColor*PolyColor*2, meaning a textured poly with R=G=B=0.5 gives the original texture colors. (Have a look at the OS4 Bugzilla or just try to set the RGB scale to 2 or 4 in the multitext demo and you'll see what I mean. Works with the R100 driver, not with the R200 one.)

@Amidog

Emulation is +/- working with gpunull.dll (with/without compiler, biosemu/biosfile etc). Sound is working (spuwave.dll) :) .

appears.

With gpuw3d.dll is the same problem.

There is a problem with screenmode requester also:

(hits after choosing mode)

@rzookol

Looks like I have som debugging to do.

Interesting that the MorphOS M68k emu identifies itself as a M68060 ("M68060 optimizations enabled."). That's probably not optimal as the PPC can do 64bit multiplies unlike the M68060, not that it matters much but anyway...

Ok, this is what's making gpupeops crash with a divide by zero:

void InitFPS(void)
{
if(!fFrameRate) fFrameRate=200.0f;
if(fFrameRateHz==0) fFrameRateHz=fFrameRate; // set user framerate
dwFrameRateTicks=(TIMEBASE / (unsigned long)fFrameRateHz);
}

_InitFPS:
.stabd 68,0,889
.stabd 68,0,890
ftsts _fFrameRate
fjne L138
.stabd 68,0,890
movel #0x43480000,_fFrameRate
L138:
.stabd 68,0,891
fsmoves _fFrameRateHz,fp0
fjne L140
movel _fFrameRate,_fFrameRateHz
fsmoves _fFrameRate,fp0
L140:
.stabd 68,0,892
fcmps #0r2.14748365e+9,fp0
fjge L142
fintrzx fp0,fp0
fmovel fp0,d0
jra L143
.even
L142:
fsadds #0r-2.14748365e+9,fp0
fintrzx fp0,fp0
fmovel fp0,d0
bchg #31,d0
L143:
movel #100000,d1
divul d0,d1
movel d1,_dwFrameRateTicks
rts


Not that I can understand how fFrameRateHz could ever be zero considering it's always assigned a non-zero value...

Could You release dll with const value :

{ dwFrameRateTicks=(TIMEBASE / 200); }

for testing ?

Sure, go to my homepage and the WIP section. Both debug and release compiled versions are included in the archive.

Thanks, with Scale and SpeedLimit set to OFF is working fullspeed.
With set to ON it hits :/

Morphos 68k fpu emulation do not set status bits. Maybe compilator generates not mos-compatible code :)

Good!

So the 68k fpu emulation is broken then. That explains why it worked fine on anything except MorphOS. Where do one report MorphOS bugs nowadays?

The SpeedLimit most likely rely on correct FPU behavior too, but I don't think Scale should care?

Hmmm... sounds like a bug in the pixel shader... I'll have a look asap. Probably the output scale is messed up then... which should be easy to fix.

NICE constructive thread! And good work there Amidog!
Try to report the MOS bug to Itix.

The best place would be the MorphOS mailing list, but that's
restricted to registered users (i.e.: those who bought a Peg).

The second best is the IRC channel #morphos at FreeNode: there is
always a good part of the MorphOS team connected, and sometimes they
are also in a good helpy mood (as can be confirmed also by some guests
of this very site )

Finally, also posts at MorphZone gets usually noticed and answered.

BTW, thank you very much for this version of FPSE. Ah, probably a WUP
compile would perform even better on MorphOS (with respect with the
68k version).

Kind regards,
Andrea

What do you mean by "fullspeed"?
Here it's damn slow...

It hits also in Actual ScreenMode+Fullscreen

According to this page there are several levels of FPU emulation in MorphOS where the fastest level (3) is the least compatible. Have you tried to change the FPU emulation to level 1?
