C64 Studio is a .NET based IDE written by Georg Rottensteiner.

This app supports project based C64 assembly. The internal assembler is using the ACME syntax.

In connection with Vice the IDE allows you to debug through your code and watch variables/memory locations, registers and memory.

Any other emulator can be set up as well if it’s startable via runtime arguments. C64 Studio allows you to compile to raw binary, .prg, .t64 or cartridge format (.bin and .crt for 8k and 16k).

Additionally to this C64 Studio comes with a charset and sprite editor.

Version history:

14.07.2011 – 1.4:

• Added warnings for unused labels.
• Speed up compiler (less restart of parsing)
• Following element dependencies on build.
• Disallow circular dependencies.
• Readjusted watches after restart.
• Save current open document and position.

There’s still a little bug in the sprite editor I haven’t been able to reproduce involving flipping (press X/Y) and/or copy/paste.
