Emulator Issues #11164
TMEM emulation regressions
NHL Slapshop -
Metal Arms: Glitch in the System - GM5E7D
Sonic Riders - GXEE8P
Tak and the Power of Juju - GJUE78
What's the problem? Describe what went wrong.
TMEM emulation breaks FMVs in these games, causing them to get stuck. NHL Slapshot breaks differently, with the same left/right eighth of the screen repeating itself on each half of the screen. NHL Slapshot actively cannot be played, while the other games function normally outside of FMVs.
What steps will reproduce the problem?
Is the issue present in the latest development version? For future reference, please also write down the version number of the latest development version.
Is the issue present in the latest stable version?
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.)
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
A fifolog of NHL Slapshot already exists on fifoci
What are your PC specifications? (CPU, GPU, Operating System, more)
NVIDIA GTX 1070
Is there anything else that can help developers narrow down the issue? (e.g. logs, screenshots,
configuration files, savefiles, savestates)
From the forums...
"Switching the texture cache slider while a cutscene updates the current cutscene frame to actually display. It'll be frozen on that frame until the next time the texture cache setting is changed. Rapidly swapping between "Safe" and "Fast" settings allows you to view the cutscene. The faster you swap between them the faster the framerate.
By default my screen flashes purple whenever I change this setting during a cutscene, so doing it rapidly causes annoying rapid purple flashing. Enabling "Immediately Present XFB" eliminates this purple flashing entirely."
Changing the "Disable EFB ram copies" on or off also updates the cutscene frame.
