So far, I have tested games from the following systems: SNES, NES, Master System, Mega Drive, PSX, Saturn, N64, GBA, GameCube, Neo Geo, and PC Engine, and I haven't faced this issue. I am using the image from the above link.
Because the offered image is not official, I suggest using your manually installed setup and opening a new topic with the requested information, as suggested here: https://retropie.org.uk/forum/topic/3/read-this-first
As a suggestion, you might try using a different controller or gamepad, just in case the fast forward function is stuck
First, reset the previous mapping: You can do this from the RetroPie Setup by choosing Configuration Tools > EmulationStation and selecting the Clear/Reset option. Then, configure the new controller or keyboard and test again.
