If a picture is worth a thousand words and a video is worth ten thousand, a GE frame dump is worth a million words.

Tried to catch 3 times, the recording only started after the fps stabilized so I'm not download them. For the 4th try the debugger freezed at "Recording" now it's not connects.
@Gamemulatorer what is that? How can I add it?
Create compat.ini file in your psp/system folder.

Here we go...
@Gamemulatorer I mean mine is running with full speed, but there are places where I stand and starts spinning I got these drops but only for a second or half. This is why I can't catch GE dump from the slowdown.

Both happens in OGl and VK backend? Are you using the 120hz screen refresh rate of your phone?
Yep, OGLES and Vulkan. I'm using my screen on 60Hz.
What happen if you turn off hardware transform?
No, i think there is an actual issue in this game, timing maybe, that should be investigated
This is the same as https://github.com/hrydgard/ppsspp/issues/12313#issuecomment-903581961 I got stable fps if I overclock it.

Or this might be improve if ever sync to host is implemented https://github.com/hrydgard/ppsspp/issues/15081
An FPS drop to 50/60 can't even possibly be helped by that, no. That's a request to scale game speed to the ratio of your display speed (for example, if your display is 75 Hz, to run at 125% speed, or if your display is 59 Hz, run at 98% speed.)
In this case, the game is (sometimes) outputting less than 59.94 frames per second. Even if you fast-forwarded emulation constantly to 125% for a 75 Hz display, it would still be outputting 16% less frames than it should, so you'd still get a frame drop.
It would help if someone can check this on a real PSP, just so we're sure there aren't FPS drops in the game itself. It's probably some timing issue, though, I guess... usually we're faster than we should be, though.

We need 30/60 fps cheat codes for this game its the only way to play normal.

There is FPS drop in and around the center room of the level. However, with PPSSPP the game also achieves much higher framerates on the first level in general. See https://github.com/hrydgard/ppsspp/issues/20296#issuecomment-2868848473
