Can you say what the expected outcome is? From my tests before and after EXECing that code: T3 (in dosbox): Before: slow notes, after: slow notes Vcc (in wine): Before: slow notes, after: slow notes XRoar: Before: slow notes, after: fast notes (tempo changed) Real Dragon 64: Before: slow notes, afte...

So, following that rather good suggestion, here's a new demo!

1. Rotate 2 asteroids on one frame and the other 2 on the next frame. Thought about this earlier today, thought it might look a bit funny. 2. Precalculate the points for 1/4 of the rotation and then jiggle the x and y to make the full set. 12 points * 2 bytes * 64 angles? = 1536 bytes per asteroid ...

No, that's all you can "do"... Just a proof of concept really (and *really* a proof of "I don't think I can do much with this concept" ;) ). I like the spinning too, it would be a lot of sprite memory to store each "frame", so I'm a bit sad that I can't take it much further. Unless anyone can think ...

This has been keeping me out of trouble for a couple of weeks: http://www.6809.org.uk/tmp/da/demo/demo3.cas It's all done "properly", with actual multiplies and actual line drawing. But any more on screen and it would slow down too much, so I don't think this can become an actual game without replac...

Added some disk image formats (though shied away from completely describing DMK and just left a link). Tweaked some of the earlier headings to s/DMK/JVC/. I wonder if it's right to document the CAS format as *being* the Dragon's blocked tape format - the CAS itself is usually just treated as a raw s...

Oops, yes. Applied a similar fix across all the modes but sdlyuv does things differently... Fixed now.

Suggestion taken (it was i586 before, which I suppose is going back a little too far...)

New build as i686, including DLLs: http://www.6809.org.uk/tmp/xroar/xroar- ... dows32.zip

http://www.6809.org.uk/tmp/xroar/xroar-snap-20091203-windows32.zip Three changes: 1. Don't special-case Windows, use 44kHz audio with a smaller buffer. This could actually make things *worse*, but: 2. Clear audio buffer to last sample output. You can still get breaks in the audio if things are too ...

I have spotted a potential flaw in the '-vo sdl' code - is this any more successful at toggling fullscreen? http://www.6809.org.uk/tmp/xroar/xroar-snap-20091202-windows32.zip I've updated all my MinGW stuff now too, though I doubt that will affect things much. Got a basic SFML video module going, bu...
