I'm not sure you can eliminate it, but it can be reduced, here's how
Edit the boot cmdline
Type - sudo nano /boot/cmdline.txt
It should display
dwc_otg.lpm_enable=0 console=ttyAMA0,115200 kgdboc=ttyAMA0,115200 console=tty1 root=/dev/mmcblk0p2 rootfstype=ext4 elevator=deadline rootwait
Add 'quiet' to the end of the script
dwc_otg.lpm_enable=0 console=ttyAMA0,115200 kgdboc=ttyAMA0,115200 console=tty1 root=/dev/mmcblk0p2 rootfstype=ext4 elevator=deadline rootwait quiet
Then Left Ctrl and x, y (yes) to over right, Enter to save
Now on load the boot text will be 'minimal' but wont eradicate it completely
Thank you, but the problem is not only the boot text: both MAME4All Pi and PiFBA generate some text in terminal while running some games (internal verbose warnings, errors, etc.) and the same text remains visible while Advancemenu switch resolution before loading another emulator + rom.
I know there is an option (ui_gamesg)
to show "Loading" (or another text) instead of showing the switching resolution, but the display_restoreatgame
value needs to be turned off creating some display problems.
If every time AdvanceMenu runs an emulator it could be possible to run also the "clear" command (that cleans up the terminal screen) it would be perfect (eg: "clear & ./mame dkong")
So I tried to add it in the emulator line in advmenu.rc but without success.
In my opinion it can be done editing the AdvanceMenu source, but I don't know how or where (I'm not a developer).
