@superfella still, that's the information I would need to diagnose. take it or leave it...

I wrote a tutorial a while back with some tips to help with the disc swapping and save state mess. https://retropie.org.uk/forum/topic/19269/tutorial-painless-apple-game-emulation?_=1592965674049

One thing I would like to see is write protect in the emulator. Games written in Apple Pascal need the boot disc write protected or the boot hangs. This includes the first 3 Wizardry games. Like I discussed in the tutorial, you currently need to use file permissions as a workaround for this.

Well I solved my problem. Found that somehow I had given ownership of the apple II ROMs to "root". I restored ownership to "pi" and high scores are working now.

@alanhorman pressing f1 would have told you this as well.

@Zering Please open a new topic - don't necro post. Thank you.

@telengard

Did you ever figure out how to set/unset the framebuffer settings after launching advmame?

Unfortunately no. I reported the issue back in April of this year, but unfortunately the same behavior still exists in the latest AdvanceMAME 3.9. Currently, I believe the only solution is to reboot RetroPie after AdvanceMAME has been launched during a session to reset the framebuffer.

Like any big project with limited contributors, bug reports known to affect more users are often prioritized. That being the case, it might help for those affected here to add a comment to the thread. Nothing pushy of course. Just a simple "same here" type statement would do the job.

@ccb9951 you should delete the config, uninstall linapple and reinstall from binary. You dont have to mess with any settings in the config other than the controller (and whether you are using a mockingbird or a mouse. You can set color too If you want to change it but you can change that with f-keys. But you dont need to change any disk drive settings. That will work right out of the box.

Well, I don't know if it's the problem but I just found out that my intellivision games are not working any more... Blank screen and back to the menu.
Mame games seem to be OK.
About Apple, I tried with games zipped and unzipped by adding extension .zip in the es_systems.cfg

I found the problem about the intellivision games...
It comes from the keyboard hack files I created.
I removed them all and replace the emulators.cfg as well.
Now I can launch them. But without the keyboard hack !
