Re: Beginner's ASM Tutorial: Multiplatform Z80 ASM development videos... with vampires!

that is pretty interesting thanks

so if a digit is zero and we subtract one, the result will be 255
so does daa fix the result to 9 (and activates the carry flag)?


so daa also allows someone to use nibbles?

Re: ChibiAkumas for Spectrum 128K

oh does the ac current in the uk running at 50hz trigger the telly update and the spectrum crystal? that would make sense.

Re: Moving sprites

you are using windows? on linux you can create a 'makefile' which really helps, to get makefiles running on windows is a hassle. I've never learnt how to do bat files on windows. the makefile basically compiles your game and runs the emulator...only if it compiled successfully..which is very useful ...

I think part of the reason it's funny is the impression of Sam with the dutiful voice, saying the commands :D

Re: The Definitive Programmer’s Guide to Using the Floating Bus Trick on the ZX Spectrum

thanks, so it seems you have to detect if the machine is a 2+a and then implement the new floating bus routine

Re: Double buffering on the Spectrum

" used the stack to copy the data and also rearranged the off screen buffer to a more sensible layout with each line following the other in memory."

this does sound like the best way for a lot of games
