mo65x-rs

stands for My Own 65 eXpandable emulator written in Rust programming language. The project has educational motivation and is a genuine project based on technical specifications of 6502/6510 family microprocessors. See the screenshot of assembler mode running slightly modified program "demoscene.asm" from http://www.6502asm.com

Project is based on original version written in C++, available here https://github.com/rjaremczak/mo65x. This version is a terminal application with extra window for showing frame-buffer's content. Functionality is almost identical with the original version. Several functions like assembler or disassembler have been implemented in command line interface. Please launch the app with --help to see what are the options.

Console mode

When started in console mode (interactive mode) all options available through GUI in original version are now implemented in command line. In short these are:

• l <address> <file-path> - load binary file at given address
• d <address> - set starting address of disassembly view
• m <address> - set starting address of memody dump view
• reset - trigger hardware reset
• nmi - trigger NMI request
• irq - trigger IRQ request
• sb <address> <byte-value> - set byte at address to given byte value
• sw <address> <word-value> - set word at address to given 16-bit value
• pc=<word-value> - set PC register to given 16-bit value
• sp=<byte-value> - set LSB of SP register to given 8-bit value
• a=<byte-value> - set Accumulator to given 8-bit value
• x=<byte-value> - set X register to given 8-bit value
• y=<byte-value> - set Y register to given 8-bit value
• n=<bit-value> - set Negative flag
• v=<bit-value> - set Overflog flag
• d=<bit-value> - set Decimal Mode flag
• i=<bit-value> - set Interrupt flag
• z=<bit-value> - set Zero flag
• c=<bit-value> - set Carry flag

All expected and displayed values are hexadecimal, except the binary values of the flags. Press ESC to quit the emulator.
