CBM prg Studio is a Windows IDE which allows you to type a BASIC or machine code program and convert it to a '.prg' file, which you can then run in an emulator or on real hardware. It also includes character, sprite and screen editors and a fully featured 6510/65816 debugger.

CBM prg Studio Version 3.2.2 is released. There are a lot of new features in this version. I’d really appreciate it if you report any bugs you find or have any suggestions/comments.

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 a real C64 / VIC20 or PET if you’re feeling brave and have the right kit.

CBM prg Studio is the result of merging C64PrgGen and VIC20PrgGen. Adding new features and fixing bugs in two apps which were 95% similar was a bit of a nightmare so merging them made sense.

It was also a good opportunity for a face lift and to add some new features, such as:

• Programs are project based, meaning all related source files, sprite files etc. are kept in one place and multiple source files can be linked more easily.
• Tabbed MDI.
• Syntax highlighting.

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.

Improvements:

• Import binary file as disassembly.
• Set sprite scratch pad background colour.
• Keyboard short cuts for collapsing/expanding regions.

Bug Fixed:

• Assembler:
  • Generate to disk image.

• Basic:
  • Improved syntax highlighting.
  • Wrong case used when commenting certain lines.
  • Commenting blank lines.

• General:
  • Menu and/or tool bar was hidden occasionally.
  • Saving to network drives.
  • Source overview settings not retained.
  • Display problems with medium and large fonts.
  • Better file handling with network drives.

CBMPrgStudio v4.0.0 by Arthur Jordinson (Released October 2022) - It's been over two years between releases (v3.14.0 being previous), but it was well worth the wait!  If you do any kind of coding for the Commodore 64, VIC-20, Commodore 128, Commodore 16, Commodore Plus/4 or Mega 65, then you're going to want to check out this development environment. There are so many cool features and capabilities that I'm not going to bother listing them.  You need to head over to https://www.ajordison.co.uk/ and see for yourself.
