Can the VERA's FPGA be reprogrammed?

On the real hardware, there will be a way to reprogram the FPGA image if necessary to fix any bugs that are discovered after release. (This involves putting a jumper on the VERA board to enable access to the flash chip from the CPU.) So yes, if you would like to hack around you can, it is (will be)...

Some VERA questions

1. If the horizontal pixel counter equals DC_START the output will be enabled, at DC_STOP it will be disabled. So if DC_START is bigger than DC_STOP, DC_STOP is basically ignored and the image will be displayed up to the end of the line. 2. Sprites are rendered in order of their index, so higher in...

320x240 resolution

I think in the end someone should create a test suite of programs to test the corner cases on both real hardware and the emulator to test they produce equal results. For the real hardware, in interlaced mode it only renders the lines that are actually displayed for that field. But regarding the lin...

Hi from the Netherlands (X16 VERA Designer)


Eventually probably yes. But don't expect this until the system has been released and on the market for some while.

Black area at bottom of emulator

The hardware really only has one output resolution: 640x480. 320x200 isn't a resolution that is natively supported by VERA. As far as I know the kernal has this 320x200 resolution as part of the GEOS drawing code, which Michael didn't yet update to make use of the full 240 lines height. As Stephon ...

Hi from the Netherlands (X16 VERA Designer)


Hello all,

My name is Frank van den Hoef and I am responsible for the design of the VERA module (the audio, video and storage hardware module), which is part of the Commander X16.
