Sorry for sort of necroposting, but I was curious about combining gigascreen (frame flickering) and Timex HiRes mode. As far as I understood, it is possible with TC2128 at least. I would like to make a proof of concept, so I need a bit of help, since I'm not really familiar with Timex machines.
1. Is there any emulator supporting TC2128 memory layout?
2. May be the same effect could be achieved on TC2068 with some additional hardware? As far as I understood, ram screen banks can be switched with appropriate cartridge banks. Would it be possible to be used to achieve two hires screens on TC2068?
3. Now about color usage. As far as I see Hires can use global INK+PAPER setting.
Bits 3-5: Sets the screen colour in hi-res mode.
000 - Black on White 100 - Green on Magenta
001 - Blue on Yellow 101 - Cyan on Red
010 - Red on Cyan 110 - Yellow on Blue
Can this setting be switched every frame to achieve two different sets of colors in total? So a palette of 4 colors could be used instead of black+gray+white?
