A83: LDIR timing / saferam1
My problems with the AND sprite routine have been solved. I've
now got a fully functional AND XOR routine that is very fast. I still want to
know what the correct timing is for LDIR (1+21*[bc] ?). Also, when I write 768
bytes of data to the saferam1 location (8265h), my program scews up sometimes
when I quit it. This only happens when I write/read a lot of times to this
location. Should the APD(?) ram at that position be rewritten by 0's, or is the
'safe ram' not as safe as stated?
Thanks in advance,
Frank Schoep
