Rust library and command line interface for communicating with Ultimate-64 and Ultimate-II+ devices using the REST API. The library is used in the Ultimate Manager GUI application.

Works with Linux, macOS, Windows. Either download a pre-compiled binary, or compile and install using cargo, provided that you have a working Rust installation:

cargo install ultimate64

ru64 HOST COMMAND <OPTIONS>

Where HOST is the IP address or hostname of the Ultimate device on your local network. Alternatively specify this in the environmental variable ULTIMATE_HOST as assumed in the following examples. ULTIMATE_PASSWORD may be used to specify a network password for your Ultimate device.

ru64 --help                            # show available commands
ru64 info                              # Show device info (type, core version etc.)
ru64 run skate_or_die.prg              # load and run external PRG file
ru64 mount desert_dream.d64 --run      # mount external image and run
ru64 play yie_ar_kung_fu.sid -n 2      # play SID tune
ru64 play enigma.mod                   # play Amiga MOD tune
ru64 load sprites.dat --address 0x2000 # load data to memory
ru64 peek 0xa7ae --dasm -n 32          # disassemble memory
ru64 poke 0xd020 3                     # write single byte
ru64 poke 4096 --xor 0b0000_1100       # bitwise manipulation
ru64 poke 0x0400 0x20 --fill 1000      # fill memory
ru64 type $'print "hello"\n'           # Emulate keyboard typing
ru64 pause                             # pause machine
ru64 reset                             # reset machine
ru64 stream -n video --start           # start VIC video stream
ru64 screenshot -o screen.png          # take image snapshot of VIC stream

Addresses can be hexadecimal (0x1000) or decimal (4096).

An experimental, cross-platform GUI is available with cargo run --release --example egui. Requires a Rust installation, see above. Currently only a VIC stream viewer is implemented.

• Compiled, small, and cross platform with no external dependencies
• Mount and run external disk images
• Play SID and MOD files
• Remote screenshots to disk or, if support by terminal, the console
• Emulate keyboard typing w. unicode to PETSCII conversion
• Convenient decimal, hexadecimal, and binary input
• Bitwise operations for memory manipulation
• 6502 disassembly
• Load address detection
• Network password support
• First class memory safety due to Rust
• Modern CLI with subcommands
• Excellent error handling; error messages; and input validation
• Can be used either as a CLI tool or as a library
• Precompiled binaries for Linux and Windows (mac users should use cargo, see above)

• Disk image manipulation
• Memory bank switching for RAM access
• Ultimate configuration handling
