Hi, after a long break, here is another disassembly from me: Cosmic Ark.
I didn't find to many new things, except that this is the first game I know, that uses "fractional addition techniques". This was required by the Stella Programmer's Guide (see page 16) to make conversions from NTSC to PAL much more accurate.
I had a quick look at a few other Imagic games, and they seem to have used this technique generally. Compared to the simple conversions of Activision (or my own), this is IMO a major quality improvement.
And Cosmic Ark game was originally planed to have a non-cooperative two player
mode.
See the my notes at the top of the source for more details.
Have fun! Thomas _______________________________________________________ Thomas Jentzsch | *** Every bit is sacred ! *** tjentzsch at web dot de | << CosmicArk.zip >>
