Version 0.4

Mended a couple of pixel faults within the MODE 5 screen code. That's what
happens when you create huge data tables 'by hand'. Also a slight MODE 1
pixel problem.
Added 4 'undocumented' opcodes to get Zalaga up and running.
Sorted the BCD (Well Hopper now works - Zalaga runs, but imperfectly - a
couple of sprite faults - I think this is to either do with the palette
changing to simulate animation or the BCD).
The Sentinel ran first time! (I had expected some hassle from this program
as Geoff Crammond usually does lots of tricky exact timings).
FRAK! also ran first time!


Version 0.3

First attempt at graphics added. Uses a tweaked version of the 640x350x16
mode. If anyone could supply me with a tweaked 640x264x256 colour mode it
would be much appreciated. Yes, I mean 264 not 256...

A Rather stupid and pathetic Timer 1 bug in the VIA's was found and destroyed.
It was this that was messing up the system clock and key repeats. Who would
have thought that adding 8 lines of C code, would result in a 1200% speed up!
Not me that's for sure!!!!!!  But it did, honestly.



Version 0.2 - Still want a name for the emulator.

Shifted down the all mode 7 characters by 1 pixel, that aren't graphics.
Fixed the pound sign graphic characters.

Cursor now blinks once every 25 frames in mode 7. This is same rate as the
flashing characters - which now flash instead of being permanently flagged
as 'on' never toggled to 'off'. In my observations flashing characters
blink on and off once in a second (on the BBC).

Keyboard half sorted. (Key repeats work slightly better now).



Version 0.1 - first public alpha release
