a209ae76ca Adds keyboard input from SDL. 2017-11-05 21:16:14 -05:00
Thomas Harte
0116d7f071 Added a platform-neutral route for feeding ROMs to machines, in a platform-dependant fashion; implemented for the CPC. 2017-11-05 20:12:01 -05:00

512e877d06 Ensures proper initialisation of the delegate pointer. 2017-11-05 20:11:18 -05:00

1e1efcdcb8 Pushes far enough along the path of having the SDL version do work that it becomes obvious I've never figured out the correct course of action if there is no sound output. 2017-11-05 12:49:28 -05:00
Thomas Harte
bc2f58e9de Starts the process of adding an SDL-based 'kiosk' (i.e. TV UI, or even UI-less for now) mode. 
Specifically, introduces to the Mac side of things an SDL target with, so far, enough logic to create a window and pump SDL's events, after having decided which machine and configuration it should use.

5a3ca0e447 Adds output for modified CPC DSKs. 2017-11-03 21:10:22 -04:00
Thomas Harte
e384c50580 Switches FileHolder to have a usage much closer to FILE *. 
Thereby opens a route for file format implementations such as that appearing for CPC DSK that create an in-memory copy and perform a full rewrite.

f807a6b608 Generalises the concept of multiple samplings of an FM/MFM sector, simplifying CPC DSK support and paving the way for generic weak/fuzzy bit support. 2017-10-31 21:32:28 -04:00
Thomas Harte
833f8c02a4 Switches the CPC DSK implementation to building an in-memory version of the structure up front. 
Preparatory to making these things writeable.
