CartographPC is a Windows application created to assist in designing tile-based datamaps. This devtool serves as a companion piece to our C64 native Cartograph devtool.

The original purpose of CartographPC was to enable us to take nice screenshots of our datamaps without having to take four or six screenshots of smaller windows and piece them together.

CartographPC has since grown into a full editor with the benefit of being able to load datamaps created on the C64 directly into memory and edit, save, and move them back to C64 without much hassle.

It works by creating datamaps using tilesets created on C64 with the old, but popular, ultrafont editor. Datamaps can have dimensions of 1 to 255 tiles horizontally and 1 to 127 tiles vertically. CartographPC allows the user to create a datamap as small as 40×25 tiles (one screen) and up to 255×127 tiles.

VirtualC64 emulates a Commodore 64 personal computer on your Macintosh. I wrote the software with two major goals in mind. First, I wanted to create an emulator that can be used as a demonstrator program in a first year or second year course on computer engineering.

To achieve this goal, I have integrated various debugging capabilities that let you peek inside the CPU, RAM, ROM, or one of the custom chips. Second, I tried to make the emulator as user friendly as it can get.

In short: VirtualC64 tries to combine the ongoing fascination of the ancient Commodore computers with the great user experience of today’s Macs.

Changelog:

Fixed in beta 11

• 1. Fixed a bug that caused the emulator to crash during startup.

Fixed in beta 10

• 1. Emulator is now a native snow leopard app.
• 2. Internal communication between emulator and GUI has been rewritten from scratch.
• 3. Fixed a bug that caused the emulator to crash when importing the reset image in NTSC mode.

Fixed in beta 9

• 1. Emulator now supports US keyboards (thanks, Carl!)
• 2. Source code is now compatible with gcc 4.2 and XCode 3.2
• 3. Emulator can now handle D64 images with different file sizes.
• 4. Fixed a bug that caused sporadic crahes under snow leopard.
