[stella] CLD

[Paul Slocum <paul-slocum@xxxxxxxxxxxxxx>]

I'm working on a 255 game menu multicart, and during testing, every game 
worked except for Rescue Terra I.  I was looking through the Rescue Terra I 
code, and noticed the suspicious absence of the SEI and CLD commands at the 
start of the code.  Sure enough, using the PCAEWin debugger, if you set the 
decimal flag before the program runs, it crashes that same way as on my 
multicart.

So apparently the Atari normally starts up with the decimal flag clear.  I 
assumed that since every program I've ever disassembled cleared it, that it 
started out in a set state.  So I had my menu program set it before 
switching to the game.

I guess this is why the Stella Programming Guide tells you to assume that 
the Atari starts up in a completely random state.  Gotta follow the rules, 
Dan Oliver, where ever you are.
