XRoar est un émulateur Dragon32/64 mais aussi Tandy CoCo.
User-visible changes:
* Semigraphics mode 6 implemented.
* Virtual cassette writing supported. Control+W attaches a file for writing. Not available from the GP32 interface yet.
* While reading virtual cassettes, fake leader bytes are inserted when cassette motor is turned on. Improves compatibility with some CAS files.
* Cartridge ROMs can be inserted on the fly using Control+I (hold Shift to prevent autorun). Available in the usual menu on GP32.
* Windows32 UI has separate save dialog.
* Timing issue with short branches fixed (now « Dragonfire » game on CoCo looks ok).
Some behind-the-scenes changes:
* 6809 instruction loop function now keeps all registers local so compiler has more opportunities for optimisation.
* WD2797 emulation now implements CRC16, which should be useful later on when DMK loading is added (a format that preserves more information about the structure of the disk).
