@Muteki correct. These files are mostly copyrighted (there's a few cases where vendors have permitted distribution), so we can't install them automatically. Some systems run without. Eg. Zx spectrum, as the bios is included due to being permitted by the copyright holder (in this case Amstrad). Or because they use a replacement copyright free bios. Eg. There is one for the Amiga for example.

I am not familiar in any way with NDS emulation, sorry. I can work on a Pi on Tuesday to see where you can locate the config files. Do you have a SSH server running on your Pi?

Please add more info about your setup, as detailed in https://retropie.org.uk/forum/topic/3/read-this-first. The reason for the crash is probably shown in the emulator log file (/dev/shm/runcommand.log) can you get the files's contents and post it ?

@Gameeplayhard you can install KODI and play all the movies you want from your harddrive

@retropi19 sorry no. Use the 4.5.1 and update it or generate your own.

I think that's because the 1 PS4 controller appears to generate 2 input devices, so the numbering is skewed. Try the workaround proposed here.

In RetroPie, you use the setup script, go to Configuration/Tools and open the dispmanx settings, from where you can enable it for the emulators that support it (that includes basilisk).

@mitu Thanks for clarifying :)

@dabone Thanks! that worked!

I can't remember any settings for 'wallpaper' in RetroPie - are your referring to the splashscreen or the Emulationstation theme ?

@Dwarfboysim Sorry, it's the other way around, I'm using lr-atari800 not atari800

@rkoster Cool!

@bkumanchik The k is because you have loaded a "k-file," which is a specially optimized variant disk format for faster loading. It's generally noted in the game filename, like Zombies (1983)(Bram)(US)[k-file].atr It's a bit odd that you are in BASIC and see it, usually it goes away once you are in the game and it tends to be on games that are machine language. For those sorts of games, you want to disable BASIC. If your goal is to do some BASIC programming, I suggest finding a DOS 2.5 system disk, and booting to that with BASIC enabled. If your goal is to load a game and you are getting dumped to BASIC, I suggest disabling BASIC in the RGUI menu (Select-X, Options, set BASIC to disabled). I just posted a giant thread explaining most everything about Atari 8-bit emulation in Retropie here: https://retropie.org.uk/forum/topic/22392/lr-atari800-5200-artifacting-basic-and-other-guidance

@rkoster OK, thanks!

@bkumanchik yeah no problem.

@mitu That did it, thanks so much! :)

If I were to hazard a guess, I would say that changing over to a USB boot means that your USB ports are staying powered on when your system isn't running. You should probably just unplug the power source after shutdown.
