Re: [Atari800-users] Implementing cartridge types from Atari800 DOC/cart.txt

[Avery L. <ph...@vi...>]

Yes, the intent is to make compatible changes. It's more that I wanted 
to make sure that I wouldn't upset any one by "sniping" in the event 
that I ended up shipping support for these CAR types in a release before 
Atari800 did, based on information from Atari800's own dev line. But I'm 
glad that there are no issues with this so far.

I'm not worried about stability, as in practice fragmentation of the CAR 
format has not been a problem and these new cartridge types have 
actually been known for some time. If it turns out that these 
definitions are unstable, then I'll of course hold off. For better or 
worse, cart.txt is the closest thing the community has to an 
authoritative registry for the CAR format.
