Description

Game Name?

[The Dodger Demo]

Game ID? (right click the game in the game list, Properties, Info tab)

[DRDD52]

MD5 Hash? (right click the game in the game list, Properties, Verify tab, Verify Integrity button)

[37b606ab98bd93158704188513090879]

What's the problem? Describe what went wrong.

[The Dodger Demo runs at half speed (Dolphin boots the game at an initial 120 VPS then stays at 60 VPS after loading instead of always being at 60 VPS) if the debug HUD is not enabled.]

What steps will reproduce the problem?

[Run the game.]

Is the issue present in the latest development version? For future reference, please also write down the version number of the latest development version.

[5.0-10169]

Is the issue present in the latest stable version?

[No, 5.0]

If the issue isn't present in the latest stable version, which is the first broken version? (You can find the first broken version by bisecting. Windows users can use the tool https://forums.dolphin-emu.org/Thread-green-notice-development-thread-unofficial-dolphin-bisection-tool-for-finding-broken-builds and anyone who is building Dolphin on their own can use git bisect.)

[5.0-4740]

If your issue is a graphical issue, please attach screenshots and record a three frame fifolog of the issue if possible. Screenshots showing what it is supposed to look like from either console or older builds of Dolphin will help too. For more information on how to use the fifoplayer, please check here: https://wiki.dolphin-emu.org/index.php?title=FifoPlayer

[Attach any fifologs if possible, write a description of fifologs and screenshots here to assist people unfamiliar with the game.]

What are your PC specifications? (CPU, GPU, Operating System, more)

[CPU: Intel i7-8750H, GPU: NVIDIA GTX 1060,OS: Windows 10]

Is there anything else that can help developers narrow down the issue? (e.g. logs, screenshots,
configuration files, savefiles, savestates)

[Anything else here]

History

#1 Updated by JMC4789 8 months ago

Turn off immediately present XFB copies. It should help with issues like these.

#2 Updated by Anonymous 8 months ago

The bug still happens even if Immediately Present XFB Copies is disabled.

#3 Updated by JMC4789 8 months ago

Is this some kind of homebrew or something? I can't find any information on "The Dodger Demo" on our compatibility list or database.

#4 Updated by JosJuice 8 months ago

I can't find it on GameTDB or Redump either.

#5 Updated by Anonymous 8 months ago

It was a Gamecube demo that was included in early versions of the Gamecube SDK.

#6 Updated by JosJuice 8 months ago

I removed the link you posted since it provides an unauthorized download.

#7 Updated by Anonymous 8 months ago

Sorry. I'll make sure to not do that again.

#8 Updated by CelestialAmber 8 months ago

I tried editing the game id through hex editing to match its NTSC-U region, but the bug still happens. It seems really strange that a PR that only fixed region detecting code would cause this bug to happen.

#9 Updated by CelestialAmber 8 months ago

Also sorry for deleting my account.

#10 Updated by JMC4789 8 months ago

Dolphin also does less hardcoded stuff. Does the demo run correctly on console? Is there any debug output differences?

#11 Updated by JosJuice 8 months ago

5.0-4740 made it so that the game ID is not checked anymore when determining the region. If you want to hex edit the region code that Dolphin reads now, it's the byte at 0x45B (for GameCube discs). I assume that setting that byte to 02 (PAL) would give you the old behavior.

#12 Updated by CelestialAmber 8 months ago

When the region is set to PAL, the game runs at full speed when the debug HUD is disabled, but it now instead runs at 2/3 speed (40FPS and 40VPS) with the debug HUD enabled.
