Re: movea.b movea.w why these exist?

when speaking about 8bit address mode, is it not true that you can do a fast shift 8, by pushing a 8 bit to the stack and recover it as an 16 bit like this

Code: Select all

   Move.b   d0,-(Sp)
   move.w   (Sp)+,D0



or maybe it the other way around

Code: Select all

   Move.w   d0,-(Sp)
   move.b   (Sp)+,D0

Re: Can't find Degas+ manual

Hi

Re: Fast Devpac Question...

Happy birthday Peter! I remember the Bullfrog Tutorial that came with Devpac 2 on ST Format. It had at least 20 includes, incbins etc. As others have mentioned I think this is limited by available memory and not a hardcoded limit. I remember thinking if that was commercial quality code then it was ...

Re: Need idea to do something faster

for some reason i like my program to use hex numbers inside and to show decimal on the screen. You can have two separate variables, one normal int that you use for logic (e.g. bonus life when achieving a certain score) and one BCD used for display. Just increment both at the same time. yes i can se...

yes you are right mfro binary numbers.
i just write hex because its what i see in Devpac and also because i thought it made it easier to describe my problem, but i want to see them as decimal numbers :D
