GUI64 is a graphical user interface (GUI) for the Commodore 64. It comes in two designs: one is Windows-like, the other Mac-like. With GUI64 you can do the following:
- run programs and games
- manage files by cutting, copying, pasting, deleting, and renaming them
- format and rename disks
- browse your folders on your SD2IEC device
- create new disk images and folders
- view files as text and hex
For detailed information on GUI64, check out the C64-Wiki page https://www.c64-wiki.com/wiki/GUI64.
Control:
Mouse in Port #1 (mouse wheel support with adapter Micromys)
Joystick in Port #2 (right click with Commodore key + fire)
There are currently three options: the first is gui64.crt. This is a cartridge image with which you can enjoy GUI64 right after switching on your computer. The second option is gui64.prg which works great with a Kung Fu Flash cartridge. The third option is gui64.d64. Put in the disk and load GUI64 with 'LOAD"*",8,1'.
GUI64 was developed in 6502 assembly code (ACME syntax) with C64 Studio which you can download here:

To build GUI64, download the files in the "Code" folder and open C64 Studio. In C64 Studio, go to "File->Open->Solution or Project", and choose the *.s64 file. C64 Studio then opens the solution. The main file is GUI64.asm.Memory map of GUI64 v1.9

- File browser: Copy files between SD2IEC directories and images; maybe even copying files between disks in the same drive via disk swap will be possible as well
- Retrieve time from Ultimate 64 and/or SD2IECs with RealTimeClock
- Application programming interface: program your app for GUI64
