OK once i re-compile the sma of an orignanl AMX plugin, it should work in amxx right?

Generally, Yes.
But some plugins won't work ... dunno why but I think you can ask here if they don't work for any reason ... most errors are self-describing tho.

Change the #include <amxmod> to #include <amxmodx>
And Yes.
