GameBoy Assembler Plus

Assembly Tools

Description:

This program was written to be the best GameBoy assembler out there. It also features a disassembler capable of some advanced methods. Here’s a full unique feature list:

  • Dynamic addressing (AKA label support, and the ability to call and jump to them)
  • Code highlighting
  • White space can be ignored, so instructions like ” ld a , 5F” will assemble successfully. It should be noted that spaces and other characters act the same as commas, so don’t feel like you need a comma just because it’s proper
  • Auto-indenting
  • Error checking on-the-spot and highlighting
  • Support for just assembling code right away without opening a ROM
  • Read-only zones that prevent code from being written in certain areas
  • Rewrite zones, which fill a specified area with 00s so you can safely rewrite a chunk of code
  • Code previewing, which shows where your code will be written line-by-line
  • Safe file IO (warnings when you would lose your code if it was unsaved)
  • Code insertion - “This generates code compatible with any language that uses curcly-bracket array assigning in the case you might want to make software automatically insert your assembly into a ROM. This only generates the code containing the values, so you still have to write them to the proper addresses yourself.”
  • Disassembling
  • Trace disassembling - the disassembler will start at a certain point and follow jumps, calls, and returns until the call stack is empty
  • Bank-changing emulation - this is very weak and only emulates LD A,# and LD (####),A instructions, but when the accumulator is written to 2000-2FFF, the program will attempt to change the current bank if possible. Perhaps full emulation will come in the future

Update Log:

1.0 - Initial Release

1.1 - Fixed a bug that made instruction E9 appear as jp (hl) when it should just be jp hl. Also added instruction DE (sbc a,n)
