Ok, sorry for using directly in the wrong folder. I upgrade, it's work, I can open Snake and see the project elements. Now I can't launch the game "Can't find the .prg to run!" Maybe this is normal? Thank you for your quick responses. I find it a fascinating project.
Is there this same type of software that could be used on the real c64 (and at the same time also on windows)
I will find it nice to be able to work on the original machine.
Do you know if this type of project exists Or maybe you are thinking of doing it later? Because you can program on the C64 but from what appears to be quite difficult, it would be possible to program in Basic but with a more pleasant interface. With a sprite editor for example. Like yours which looks pleasant to use.
