CBM .prg Studio




A handy Commodore 8-bit program development utility for Windows


News


21st December 2013 - CBM prg Studio Version 2.9.0 released. There are lots of new features (and bug fixes) in this version. See the download page for more info. As usual, thanks to everyone who reported the problems in v2.8.0 and suggested new features for this version. Your feedback is much appreciated and a vital part of CBM prg Studio's continued improvement!


What Is It?

CBM prg Studio allows you to type a BASIC or machine code program in using a nice Windows environment and convert it to a '.prg' file which you can run on an emulator, or even real hardware if you're feeling brave and have the right kit.


The following machines can be developed for:
  • Commodore 64
  • Commodore 128
  • Commodore VIC 20
  • Commodore 16
  • Commodore Plus/4
  • Commodore PET BASIC 2 machines, e.g. PET 2001
  • Commodore PET BASIC 4 machines, e.g. PET 4000/9000
What CBM prg Studio isn't is a front-end for tok64, cbmcnvrt, bastext or any other tokeniser/detokeniser/assembler. It's all been written completely from scratch.


Follow the download link for more details.


Features:

  • Multiple source files (assembly or BASIC) can be build to one destination,
  • 6502/6510 Assembler/disassembler/Integrated Debugger,
  • Program import (.prg, .T64 or .D64/.D71/.D81),
  • Program export (.prg, .p00),
  • Sprite editor,
  • Character editor,
  • Screen Designer,
  • A Screen Code Builder, for using those pesky print control characters,
  • Memory Viewer,
  • Binary file import/export,
  • .D64/.D71/.D81 Creation Tool,
  • BASIC Constants,
  • Code formatting and renumbering,
  • Automatic assembly code formatting,
  • Tabbed MDI interface,
  • Comprehensive help, including tutorials,
  • Plus many others.


To Do List


Here are some features which I'm either working on or planning to:
  • 65816 Assembler
  • SID
    • Being able to play the sound created with the SID tool,
    • A 'tracker' style tool - no details as yet!
    • Some progress has been made with this recently, so you never know it might see the light of day!
  • Integrating pBASIC (see download page) into CBM prg Studio.
  • Bug fixes, as usual.
I'm open to suggestions if you have anything you would like adding to CBM Prg Studio, or change the way something works.


Background

Way back in the mists of time I was given a VB.NET project at work. I'm a C++/C# programmer by trade and I hadn't touched VB since version 3 (many years ago) so I was a bit rusty to say the least. Typically, I wasn't given any investigation time and was expected to just get on with it. I'm sure any programmers out there are familiar with that! Anyway, I was scrabbling about looking for a nice little project I could do in my own time to get me up to speed with VB.NET and at the same time I was into playing around with the various C64 emulators and tools, particularly tok64. That's how C64prgGen (CBM prg Studio's predecessor) came about really as I noticed that there weren't many (if any) code generation tools with a GUI front end. Admittedly I hadn't looked very hard though. CBM prg Studio is the result of 'merging' C64 and VIC20 PrgGens.
