Question on 8-bit, 16-bit, 32-bit...Hello, Sorry, this is probably a really dumb question(and something I should know by now :)). I tried doing some searches about this but came up only…
Your question has no answer without context and your register name assumtions assume a register system based on 8 byte registers being combined - which is not the case for many processors. -

Ok, so wot I'll do is insert that missing byte in the TZX file and see it works properly. I do hope that is the only reason y the TZX files aren't working. If not, I'll just have to download the perfect tzx from the archives! :) -
