- Fancy dialogs for tweaking emulator options and peripherals. Built-in help is not finished yet.
|
|
- New peripheral handling to support multiple monitors/drives/io extenders
|
|
- Option for cpu speed throttle (1x, 2x, 5x, 10x, 100x)

- 16 COLOR MONITOR
|
|
i've added a 16 color monitor to the emulator; same as the monochrome monitor, but with attributes
|
|
|
|
same registers as the monochrome except
|
|
attributes line buffer from 0x60->0xaf
|
|
format: xxxx yyyy
|
|
xxxx = background color (0 bits in character rom)
|
|
yyyy = foreground color (1 bits in character rom)
|
|
|
|
monitor type @ 0xff = 1 (monochrome should be 0 as is now)
|
|
|
|
blitter
|
|
blitter enhancements required for the 16 color monitor
|
|
blit mode 0x07:
|
|
0x1: almost the same, attribute value @ 0x09
|
|
0x2: remains the same (invert)
|
|
0x3: shift also shift attributes
|
|
|
|
colors
|
|
matches the commodore-64 color table: http://en.wikipedia.org/wiki/List_of_8-bit_computer_hardware_palettes#C-64
|
|
|
|
|
|
examples
|
|
in pseudo-C terms, you set color like this:
|
|
// select row first as normal, then do:
|
|
poke (0x360+$column, (bgcol << 4) | (fgcol & 0xf))
|
|
|
|
forth example (by BloodyRain2k)
|
|
HEX : colors 30 0 DO I 300 C! 30 0 DO J 3 / 10 * I 3 / + 360 I + C! LOOP LOOP ;
|
|
|
|
tetris.img (with colors :) and colordemo.img available within the archive.

Minor changes in keyboard handling
|
|
- key typing works even if emulation is not in running state
|
|
- you can use F6 to access built-in monitor as pause/break key not exists
|
|
on some systems
|
|
- probably now not US keyboards works well (like altgr+q)

WARNING: CPU core changed so probably you need to change your programs
|
|
|
|
updated due to new RedPower release (RedPower Control 2pre5b2)
|
|

- CPU: Fixed interpretation of the E flag
|

|
|
- CPU: Fixed the carry flag for SBC
|
|
- CPU: Add unsigned divide support (C=0), fix divide bugs
|
|
- CPU: Added unsigned multiply support (C=0)
|
|
|

command line parameter "-nobug" removed as the SBC bug is fixed
|
