DevpacNG Atari brings the premier 68000 integrated development environment for the Atari ST, Mega ST, TT030, and Falcon030 into the modern era.

Featuring a fully integrated GEM editor, the blazing-fast Gen macro assembler, and the powerful Mon symbolic debugger, DevpacNG adds native support for advanced processors (including 68060 and Apollo 68080), vector AMMX disassembly, and refreshed color themes.

      • Green CRT
      • Amiga Workbench
      • Purple
    • Added 68080 and 68060 target processor selectors in the Assembler Options menu, passing +p=68060 and +p=68080 to the build pipeline.

  • Mon Debugger with Extended Capabilities:

    • Native 68080 & AMMX vector instruction disassembler.
    • Extended 64-bit and 128-bit register windows for Apollo Core registers.
    • Disassembly of 3-operand BANK-prefixed integer instructions (add, sub, and, or, eor, lsl, lsr, asl, asr, rol, ror, addq, subq, mulu, muls).
