/***** Gun Bird Japan Crash Notes

The Following Section of Code in Gunbird causes reads from the

0028B6: 720FC041           moveq   #$f, D1

This causes Gunbird to crash if the ROM Region Size
allocated during loading is smaller than the SMH_ROM
region as it trys to read beyond the allocated rom region
