/* search for [Kayamon] for any changed parts.
 *
 * Changes are based from Antiriad's / [J3d!] 27raine version,
 * along with others in order to get MZ80 v3 to work.
 *
 * Note that my changes haven't been done to the C version of MZ80, only
 * the x86 one. So any porters might need to consider that.
