That's something I don't have the luxury of in the Carte Blanche card.How much memory you have available for lookup?
The Carte Blanche card has 250Kbytes of SRAM but that isn't practical to use for a lookup table since we're using it to read/write some of the video buffer. The internal FPGA BRAM is only about 24KBytes and that's virtually all used.
The IIgs simple yet effective mode you can already implement in few hours. :-)
If you are talking about the SHR mode it's already done. :-) Charlie
