Can`t Euphoria programs run on 8 bit systems ? A Game Boy has an old 8 =
bit Z80 processor . Can an Euphoria program run on an 8 bit CPU ?! All I =
want is to make an Euphoria program run on a Game Boy ! Please , please =
, please !
I`ll do anything ! Thats all I ask .=20

Sure, if someone compiles a GB-version of Euphoria.
Though I don't think that'll happend.
Why ?
* GB can't do floating-point math. Sure, anything can be done with
some work-arounds and approximisations. But on a GB? at acceptable
speeds? me thinks not..
* GB has very little RAM.
* GB is simply too slow for interpreted languages. I mean, it runs
at what, 3MHz?
I know that there's a free C-compiler for the GB called lcc. But to be able
to compile Euphoria with it, Rob would have to make some big changes and to
be honest, I don't belive he thinks it's worth it..

Euphoria uses the upper two bits of 32 bit integers to flag whether a value
is an integer, a pointer to an atom, or a pointer to a sequence.
Making it work in 8 bits would require more than a few changes to the
internal library, so don't hold your breath.

Why a GameBoy machine?

Cos ferdinand asked if Euphoria could run on a GB.

Doesn't the GB have (at least) one 16-bit register? or maybe I'm confusing
it with the SNES.. anyways, if it does, then we still could have the two
upper bits signaling pointers, and have 14-bit integers :) Although, I'm
not sure if you can do arithmetic with this/these registers or if they're
just used for addressing.. oh well, doesn't matter.

Actually, there's a lot of different ways you could set up internal
representation. For example, you could set up a data/value pair of 8/16/32
bit numbers, the first holding the data type, the second holding the data.
Under this sort of scheme, you could just embed floats into the sequence,
instead of sticking them in structures and pointing to them. Or you could
just disallow floats entirely.

And then i asked "why a GameBoy?".

beats me..
if, for some odd reason, I'd like to do console programming in Euphoria, I'd
at least pick a more powerful console (like DC/PSX2/GBA).
