After having tried the update for a few days, I am sorry to say that I have detected several problems that the emulators included ReGBA also suffer lowered frame rates and loss of smoothness in the game, especially in games with scrolling, platforms, races, action in general ... doing overclock improves something but still does not feel smooth.
Even homebrew games that used to be very fluid like Hocoslamfy (flappy bird clone) are now no longer fluid, so they are no longer just the ports of id software, doom, heretic, hexen, wolf3d...
Now it seems that the RS-90 has trouble moving the system and games at the same time. Which makes me wonder, wouldn't it have been possible to solve the bug that caused sd crashes without changing the linux?
I am sorry to comment on these problems, but the loss of performance in this update I think is important.
