      Sorry the quality is so bad. Hopefully you can see the signal blanking out as I switch between the menu and the running system. The monitor's HDMI2 input notification appears in the top-right each time this happens.

      The output resolution is 1080p@60 in both the system and the menu (I tried to show this but it's hard to see the monitor's OSD).

      It feels more like the SDL window(?) is being recreated as I switch between the system and the menu.

      With the FKMS driver, the monitor never blanks out and switching between the running system and the menu is instant.

      Will previous Pi models have the ability to use fkms driver now?

      Very interesting, then I should definitely give it another chance on an older Pi 3 setup!

      @buzz is there any other way to have RetroPie on a multi boot? I would like to have different images of Retropie with different setups, without swapping different ssd every time.

      @mitu said in Getting AdvanceMAME to run on FKMS builds:

      Do you care to elaborate on the Video appears a bit degraded part ? I confess I didn't use advmame before, so I don't have a past reference, I just test it out on the Pi4 - the 3.9 version - to see how it works.

      Sure mitu,

      Overall, it looks like anti-aliasing doesn't work with the SDL driver. Examples:

      Vector game lines are not anti-aliased System menu font appears jagged Video Rgb Effects, such as scan2horz do not blend nicely with the game screen.

      The setting display_antialias is set to yes, but there is no visual difference when it's disabled or enabled.

      One of the draws of using AdvanceMAME is for the clean high-res Vector images, so that's a bit of a miss. But having AdvanceMAME available for rendering raster games like Cotton 2 and Baku Baku is a must-have.

      There are also some issues going in and out of the settings menu (Tab). Sometimes, when returning to the game, the screen blanks. Also, gets very sluggish and occasionally hangs. Might not be related to the driver, but different from running this on a 3B+ without Buster.

      From a cursory look at your config files

      Rewind seems to be disabled via the main config file (rewind_enable = "false"). You should enable it first.

      On a default RetroArch install, I see there's a input_rewind_btn, try setting it on your desired button input code.

      same for input_hold_fast_forward_btn and input_toggle_fast_forward_btn.

      Thanks, man. That fixed it.
