To develop on MRC6502 I will use:

• Visual Studio Code
• Kick Assembler
• Arduino IDE :: for Arduino sketch programming and serial IO to the MRC6502 system
• Phyton + Transduino.py :: to program MRC6502 RAM via Arduino
• WinCUPL :: to compile PLD configuration
• TL866II plus + Xgpro/XGecu :: to program the PLD and the EEPROM

Setup

• download and install Visual Studio Code
• download and extract Kick Assembler
• download and install OpenJdk Java 11
• download and install Arduino IDE
• download and install WinCUPL
• download and install Xgpro/XGecu

Visual Studio Code configuration

• Switch to Extension view (CTRL+SHIFT+X)
• write 'kick assembler' in the search text box and install 'Kick Assembler 8-Bit Retro Studio' by Paul Hocker
• open the settings (CTRL+,) ; write 'kick' in the search text box and in User tab set:
  • Kickassembler › Assembler: Jar  ==> full path to the kick assembler jar file
  • Kickassembler › Assembler: Main  ==> kickass.KickAssembler
  • Kickassembler › Assembler › Option: Output Directory  ==> bin
  • Kickassembler › Assembler › Option: Source Symbols  ==> checked
  • Kickassembler › Java: Runtime  => full path to openjdk  java executable file (usually in bin subdirectory)
  • Kickassembler › Opcodes: 65c02  ==> checked
• open the keyboard shorcuts (CTRL+K  CTRL+S); write 'kick' in the search text box and:
  • assign 'F6' for 'Kick Assembler: Build'
  • assign 'SHITF + F6' for 'Kick Assembler: Build and Debug'
  • assign 'SHITF + F5' for 'Kick Assembler: Build and Debug Startup'
  • assign 'F5' for 'Kick Assembler: Build and Run'
  • assign 'CTRL + F5' for 'Kick Assembler: Build and Run Startup'
  • assign 'CTRL + F6' for 'Kick Assembler: Build Startup'

Ciao!
