I am trying to use the built-in VDP to decode World System Teletext, but I am getting very unexpected results. The data structure looks correct, however the actual data is extremely garbled - for example, the framing code should be 0x27, according to the datasheet - however, I am seeing 0xEA. This does not seem to change when forcing a standard vs. autodetect. Is there any more in-depth info on how to correctly set up and test the VDP function.
