SMS_S60 v1.3b

I've been trying more different games lately and some of them didn't work as expected so I had to do some debugging and fixing.
This release fixes a couple of bugs within emulator core.

Changes introduced in v1.3b:

• Fixed "The Flash" not properly working. The guy moved alone and wouldn't allow you to play at all.
• Fixed "Rainbow Islands" showing just terrain, ignoring items and monsters.
• I'm pretty sure there are more affected games, just didn't try them all.
