Here’s some issues I found with your log that might help.

  • Enabling Accurate Multiplication is recomended in certain games. If you are experiencing graphical glitches, try enabling this option.
  • Please enable the Vsync option if you are experiencing screen tearing.

its not the graphics im worry about its the slow down thats the problem

With those games, you’ll need to wait for emulator improvements. They have more than just performance issues.

why is this game hard to emulate

was the game coded poorly or something


That’s 10 times the more SLOWER IT GETS.

and speaking of dark moon why cant you fix the slow down problem in dark moon

hopefully those games will run better in the future

like is an intel core i3 and intel(r) UHD Graphics and windows 11 and 8 GB of ram enough for pac man and the ghostly adventures 2

other games run fine except for 3 title i played like dark moon and sonic transformed and pac man and the ghostly adventures 2

Your hardware isn’t the issue. Keep in mind that emulation isn’t the same as running games natively. There’s a lot more that goes into it. For example, if you want completely accurate sound emulation, switch the audio to LLE. It’ll slow your games down to 1-5 fps in most titles. This is why we have a less accurate, but more performant version of it. Accuracy costs performance, that’s the general rule. But be too inaccurate, and you risk losing stability. It’s a difficult thing to balance.
So emulating isn’t as simple as just plug-and-play. Every game behaves differently depending on their design philosophy and game engine. So what might make one game run at 500% emulation speed, may slow another down to a crawl. This is why we reverse engineer how the 3DS does things exactly and implement those things as best as possible, so that most games behave similarly enough. But obviously, there’s still work to be done. You mentioned LM3 (Dark Moon), which requires an entire rewrite of our CPU slice scheduler to fix. Just to fix one game’s performance, a significant portion needs to be rewritten. Which requires time, expertise, testing on 3DS, testing on Citra, testing, testing, testing.

This is why some games take years to fix. What may sound like an easy thing to fix, can be one of the most difficult and time consuming things to fix.

another game called mario golf world tour does slow down in citra as well

Gonna say, it’s definitely something causing this issue. If you complete the level, when game will save the data, it gets max fps possible while effects playing. Still, that doesn’t work on “Cyli Skies”, and the question is still up. Maybe the slowdown is basically animations of the characters, since in that level Cyli goes into the sky after pressing A, and ordinary levels pac just stays on place while screen goes black. But I think it’s more of a game issue than emulator, so it definitely requires some optimizaiton.
