DracoDS v1.6 is a released emulator for the Tandy Color Computer (CoCo 2) and Dragon 32, compatible with DS/DSi/XL/LL handhelds. While both systems share a similar design and overlap in hardware, differences exist in keyboard and disk handling. The update enhances PIA handling, improves game input methods, and optimizes loading for .DSK and .CAS formats. It also boosts emulation speed by 5-10% and adjusts tape loading times. Specific games like Lucifer’s Kingdom, Katipiller II, and Shamus are reported to work correctly with improved key mapping, while others have minor optimizations. Download available.

DracoDS v1.6 has been launched. DracoDS serves as an emulator for the Tandy Color Computer (CoCo 2) and Dragon 32, compatible with your DS/DSi/XL/LL handheld devices. The Tandy and Dragon systems share a lot of similarities, both built on the same Motorola reference design. Upon deeper inspection, it’s evident that the Dragon emulated certain aspects of the Tandy hardware, making them nearly identical in some areas (like cartridge pinouts). However, there are distinctions, particularly regarding keyboard matrix management and disk controller operations. This emulator mainly focuses on Tandy CoCo 2 with standard 32K and expanded 64K support but is also compatible with the Dragon 32 and can be configured accordingly.
DracoDS Changelog:
Enhanced accuracy in PIA handling (support for DDR and masking) – sound and keyboard reading have become more reliable. A greater number of games can now properly read keys/joystick inputs.
Significant improvements in .DSK and .CAS file detection and loading. Press START to load a game… and SELECT to begin after loading.
Optimizations that can boost emulation speed by 5-10% based on the game. Tape loading has become slightly faster.
Dragon32 games default to Black/White instead of Artifacting to mirror PAL and NTSC standards.
Tandy Coco (NTSC) games are now synchronized with the DS frame drawing to minimize tearing during emulation.
Lucifer’s Kingdom (CoCo Port) is functioning accurately now.
Katipiller II is operating correctly.
Shamus is running, though it currently has no sound.
Galactic Attack no longer transitions into unexpected video modes.
Key mapping for Dungeons of Daggorath has been improved.
Numerous cleanups and comments have been added as time allowed.
