[The following is a template to help you fill out a more informative

Many games do not run yet, or have known problems. Please do not report
those games without giving any more information. That means reports like
"Game XYZ crashes" are not helpful. Instead try to include as much debug
information as possible. Also try to search the issue tracker for similar
bugs before creating a new issue.


1) Game Name and ID (as it appears in right click > properties: "GZ2P01",
"RSBE01", etc):
Pac-Man Party (SP7EAF)

2) What is the expected output? What do you see instead?
Game run without flash and freezing in any time. Soon at the start screen the problem happens.

3) Did the game ever work correctly (i.e. not have this problem) on an
earlier version of dolphin? Please specify the exact revision when the
problem began.
I do not know.

4) What steps will reproduce the problem?
1. Start Game

5) What version of dolphin are you using (32bit/64bit along with the
version as it appears in the title bar, etc)?
On what operating system, drivers, and hardware? Be sure to list OS,
graphics driver information, and video card model if you are having
graphics problems, for example.
64bits 3.0-421, Windows 7 x64 and Windows 8 Preview x64, ATI Radeon 5870 1GB. Others games works correctly.

in r6244 x64 works, not 100%, but playable...

#2 Updated by arturbc93 about 8 years ago

If disable dual cores mode, don't flash the screen, but still freeze, but only in "Press A" screen, no before.

  • Status changed from New to Questionable
  • Issue type set to Bug

Is this issue still present in recent revisions?
If so, state which version was tested.

#4 Updated by arturbc93 over 7 years ago

No more blinks, but this game still freeze on "press A" screen and if I try stop the emulation, the Dolphin stops responding.

#5 Updated by Billiard26 over 7 years ago

"If so, state which version was tested."!

#6 Updated by arturbc93 over 7 years ago

Sorry, I have tested on version "Dolphin gamelist-filter Git 3.5-383".

#8 Updated by arturbc93 over 7 years ago

No, on this version still with freeze in "Press A" screen and now I am checking than the game is starting with full speed, but go to slow speed with the time to 10fps.

#9 Updated by arturbc93 over 7 years ago

I have tested on dolphin-FIFO-BP-3.5-334-x64...

#10 Updated by arturbc93 over 7 years ago

on dolphin-FIFO-BP-3.5-331-x86 default settings, have blinks and freeze before of intro movie.

Note: I hide panic messanges, on this with default settings show a message before freeze.

#11 Updated by arturbc93 over 7 years ago

I enable panic messages on dolphin-FIFO-BP-3.5-334-x64...

1st on Play game:
"EFB: Poke Z not implemented (tried to poke z value 0xffffff at (0,0))"

2nd on save data load:
"GFX FIFO: Unknown Opcode (0x3f).
This means one of the following:
* The emulated GPU got desynced, disabling dual core can help
* command stream corrupted by some spurious memory bug
* this really is na unknown opcode (unlikely)
* some other sort of bug

Dolphin will now likely crash or hang. Enjoy."

3rd, after 2nd message -
"Illegal command 3f
CPBase: 0x0167a100
CPEnd: 0x017fa0e0
CPHiWatermark: 0x0017c000
CPLoWatermark: 0x000c0000
CPReadWriteDistance: 0x00003bc0
CPWritePointer: 0x0167dcc0
CPReadPointer: 0x0167a100
CPBreakpoint: 0x00000000
bFF_GPReadEnable: true
bFF_BPEnable: false
bFF_BPInt: false
bFF_Breakpoint: false"

4th after 3rd and repeat the 2nd message

5th after 4th and repeat the 3rd message, but change some codes:
CPReadWriteDistance: 0x00008140
CPWritePointer: 0x01682240

6th after 3rd and repeat the 2nd message

7th after 6th and repeat the 3rd message, but change some codes:
CPReadWriteDistance: 0x0000c6e0
CPWritePointer: 0x016867e0

8 after 7th and repeat the 2nd message

have more 32 messages on this sequence after the message 8, play the intro and back this messages again after intro after 6 messages begin a new messages for example "FIFO out of bounds(sz= 1048631, at 00000000)" and repeat this last message forever, but increase this number.

everything works perfectly, no blinks, no frezes, no FIFO error messages
waiting for fix

Awesome, that narrows it down very nicely.
Thanks for the legwork.

#15 Updated by JMC4789 about 6 years ago

This probably should get looked at again. Has anyone tested it to make sure the game it fixed at the time still works?
