@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.
@buzz is it possible to add the option in the retropie-setup script when installing any emulator to create also a script in the ports or emulators folder that runs directly the emulator it self ???
instead to work only by running a rom/game.
And create an extra menu in Emulationstation called stand-alone Emulators for example
for advanced users like me,i think is good to exist an option like this in Retropie.
@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
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).
