CBM prg Studio Version 3.0.0 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.

New features:

• 65816 assembler/debugger.
• Partial support for the VICE debugger.
• Bitmap import/export for character editor.
• Binary file import to Assembly source.
• Line and rectangle drawing tools for the screen designer.
• TASM support added to Source Converter tool.

Bug Fixed:

• Assembler:
  • Using arithmetic with cheap labels would fail.
  • Slow incbin performance for large binary files.
  • Wrong SYScall generation for C128 projects.
  • incbin with screen data imported all screens.
  • Assembling past the end of memory not detected properly.
  • Invalid branch not detected properly.
  • Arithmetic on WORDs not carried out.
  • Multiple characters in single quotes in BYTE sequences not assembled properly.
  • GenerateTo only created .prg files.
  • Save File As… would only save .bas files.
  • Comment tool would not comment out already commented code.
  • Incbin reporting ‘file too large’ error by mistake.
• Screen Designer:
  • Binary file export
  • Colour selection for C16 projects didn’t work.
  • Wrong screen size saving C128 screens.
  • Character set selection corrected.
• General:
  • Some code reformatting issues.
