Hi
The TSConf excel file says that X Sprite coordinate is a 9 bit number, using 8 bits from R1L and low bit from R1H. What you mean with bit $0200 ?
About border, AF port 0F (not 07 as I said before) is a 8-bit number for the border colour. How it's used the value from port FEH? Aren't palette selectors only used on 4-bit colours? And that is a 8-bit colour...

Thanks
