Description

Game Name?
Dragon Ball - Revenge of King Piccolo

Game ID?
R7GEAF

What's the problem? Describe what went wrong in few words.
On several stages, during fight sequences, Goku will randomly act like he fell off the map, and respawn with some health loss. However, this results in various glitches moving between or within areas, often leaving the stage unclearable.

Tested with both graphical backends using JIT. Have not tried JITIL or Interpreter yet.

What did you expect to happen instead?
Normal Gameplay

What steps will reproduce the problem?
The issue appears mostly random, but one spot I know has problems is the first fight against the ninjas midway through stage 2-2, though I've noticed problems in 2-3 and 2-4 when the ice mechs show up, often when picking them up after they have been defeated.

Dolphin 3.5 and 3.5-367 are old versions of Dolphin that have
known issues and bugs, so don't report issues about them and test the
latest Dolphin version first.
Which versions of Dolphin did you test on?
4.0-5826

Does using an older version of Dolphin solve your issue? If yes, which
versions of Dolphin used to work?
No

What are your PC specifications? (including, but not limited to: Operating
System, CPU and GPU)
CPU: i7 2600k
GPU: GTX 770
RAM: 8GB
OS: Win 7 64

Is there any other relevant information? (e.g. logs, screenshots,
configuration files)

Please record this and try JITIL/Interpreter.

Game doesn't run with JITIL; just created Issue 8368 to document.

Interpreter doesn't appear to have the problem, and appears necessary in some spots.

I have a savestate in the middle of stage 3-1 in a spot the problem ALWAYS seems to occur, and makes the stage unpassable. I'll post a video in a bit.

Well, that was interesting. The recording doesn't match what I recorded in game, though the issue reported did occur in the recording playback anyways...

Okay, so Interpreter works? Can you try JIT on older builds if like 4.0 and whatnot if you haven't? If you have, and it's broken then... I don't know. We'll have to play the fallback game :)

Interpreter works, so no problems on that front. I'll try some older builds when I get a chance and see if I can narrow things down a bit.

Okay, so, I have another idea. Can you go into the game properties page and turning ENABLE FPRF into a checkmark.

Actions #7

Updated by gamerk316 about 9 years ago

Nope, problem still occurs.

Confirmed on my end. Thanks a ton for the report. I will narrow down where in the PPC this problem is so it can be fixed.

The problem is that we don't handle NaNs correctly.
