GUI64 is a graphical user interface for the Commodore 64 that allows you to run programs and games, as well as to manage files by cutting, copying, pasting, deleting, and renaming them. It moreover enables you to format and rename disks, browse your folders on your SD2IEC device, and create new disk images and folders. 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", choose GUI64.c64, and in the next file browser click on "Cancel". The main file is GUI64.asm.Memory map of GUI64 v1.9

- File browser: Full implementation of file viewer (menu entry "View" in "File" menu) to examine files in text and hex mode
- File browser: Copy files between SD2IEC directories; maybe even copying files between disks in the same drive via disk swap will be possible as well
- Retrieve time from Ultimate 64 and SD2IECs with RealTimeClock
- Application programming interface: program your app for GUI64
