Hi James, the last aicasm fix uncovered a flaw in the aicasm code, ie the range checking in type_check() was never called properly. This patch fixes this up and also disables the unused 16bit instruction. This is actually a resend of an earlier patch, which appearently got lost somehow. Please apply.
