DracoDS v1.7 is released. DracoDS is a Tandy Color Computer (CoCo 2) and Dragon 32 emulator for your DS/DSi/XL/LL handheld. The Dragon and Tandy machines were quite similar - both using the same Motorola reference design and, when you really look under the hood, it's pretty clear that the Dragon reverse-engineered some of the Tandy hardware such that it was virtually identical in some spots (e.g. Cartridge pinouts). There are some differences - mainly in the keyboard matrix handling and in some of the disk controller handling. To that end, this emulator is primarily a Tandy CoCo 2 emulator with 32K standard and 64K expanded support but it also works for the Dragon 32 and can be configured as such.

DracoDS Changelog:
Improved sound driver for better accuracy. Games like Demon Attack now sound reasonably correct.
Fix for speeds other than 100% on NTSC CoCo emulation.
More tweaks to more games so they play as intended (correct joystick map, Dragonfire colors, etc).
New options to allow Analog sensitivity on a per-axis (X or Y) basis.
New option to boost volume for some games that were a bit quiet (e.g. Demon Attack).
More cleanup and minor improvements as time permitted.
