RE: Saturn Emulator
(11-13-2019 06:09 AM)cyrille de brébisson Wrote: hello,I C... masks are easy... thus: It looks like every odd nibble read (ARM read is in bytes) has to be in a buffer in order to combine it with "upper" 4 bits of the unaltered Saturn information producing an even number of nibbles (= a byte). Every odd nibble write needs first a read into a buffer before the write to yet again combine the just read upper part of the byte with the 4 bits of that odd nibble to get a full byte to be written. Was that an explanation that others in this group can understand? Is that how you did it with the HP 49/50 ARM version, Cyrille? |
