Today I released v1.0.6 of Cadmium , my CHIP-8 variant emulation and development environment.

The highlight of this release is Real-Dream support, running the original CHIPOS CHIP-8 interpreter on an emulated DREAM 6800, and a reworked core architecture that allows debugging the backend CPUs of the hardware emulations.

The full list of changes in v1.0.6:

• Real-Dream support, this is a CHIP-8 mode that runs the CHIPOS CHIP-8 interpreter from Michael J Bauer on an emulated M6800 driven 2k RAM equipped DREAM 6800 computer. It is able to execute hybrid roms that use M6800 code mixed with CHIP-8.
• Clipboard now should work on the Emscripten version in the expected way.
• On macOS instead of CTRL, the CMD key is now used for hotkeys and editor control.
• All CHIP-8 cores, the hardware emulating ones and the generic ones, are now based on a CPU interface that they also share with the real CPU cores (CDP1802 and M6800) and it allowed to move the debug ui out of the main source and handle all cores, backend or CHIP-8 generically, including debug controls.
• Breakpoints, and stepping now also works for the backend CPUs of the COSMAC VIP and the DREAM6800 emulations. The debugger controls are controlling the CPU that is selected in the disassembly panel.
