I started to think about programming a Chip16 emulator
(https://github.com/tykel/chip16).
Mainly to practice having a somewhat big project in Racket and hopefully
learning something about how basic hardware behaves.
Before even starting to program I couldn't decide how i would simulate signed
bytes.
Now, I realize these options are possible to program, and maybe not even hard,
but I'd like some advice.
Should I use integers? bitwise-and and such allow for some easy use there, but
then I'd need some special functions to sum, multiply, subtract, etc.
Byte-strings are another option, but they don't support either and, or,
addition, or subtraction, so I would have to make functions for all of those.
And then I though of vectors of 1's and 0's, which would also carry a load of
functions to define.
Is there any way I can simulate signed bytes behavior without implementing a
lot of functions? Is there an alternative that i haven't though of?
