Firmware 2.11_LC

Add Lumacode support for easy connection to an RGBtoHDMI.
After flashing the firmware, add a jumper link between pin 9 and 10 of the JTAG header and then put the mode selector switch to the right-most position (right when looking at the computer from the front side). The board then outputs a "Lumacode" signal on the luma line (green jack of the breakout cable). This can then be fed into a Lumacode-compatible RGBtoHDMI device.
Note that the "Sync" voltage level is not the same as on a regular Lumacode source because the existing electronics can not generate it, so you need to adjust this voltage in the "Sampling Menu" of the RGBtoHDMI.

Firmware 2.11

Add compatibility for the 2 MHz mode of the C128. This is used in some games to speed up calculation while the display border is drawn.

Firmware 2.10

Increased BeamReacer/SuperCPU compatibility
Advanced feature: Pixel clock generation for NTSC

Firmware 2.9

Support for the rare 6567R56A
Finally fixed timing issue for sprite DMA detection

Firmware 2.8

Fixed startup timing issue for early C64s with discrete clock generator circuit.
Optional "early" sprite DMA detection when shorting pin 95 and pin 96 on the FPGA.

Firmware 2.7

Support for PAL-N.
Optional "high contrast" palette for use with the RGBtoHDMI upscaler.

Firmware 2.6

Allow palettte settings for odd and even lines individually
Better compatibility with Ultimate II+

Firmware 2.5

Tweaked the VIC to FPGA synchronization a tiny bit to work more reliable even with very shaky clock generator chips.

Firmware 2.4

This is a bugfix release to correct the multi color text mode, I have broken in release 2.3.
Strangely, none of the demos I have checked seems to use this specific video mode.

Firmware 2.3

YES! I did it!
Finally the mod is able to play - without any glitches - the "Edge of Disgrace" demo.
Additionally I tried "Deus ex Machina", "We Are New (Fairlight)", "Brutality", "Sharp (Fairlight, Instinct)", "The Wild Bunch" and everything seems to work just fine.
