Primordial Ooze Posted October 28, 2008 Share Posted October 28, 2008 I was told that the atari 2600 couldn't handle alot of instructions. My code is as follows: rem 2600 De Amigo rem a Samba De Amimo clone for the 2600 rem Updated: October 11, 2008 rem Website: http://planetarydefense.freepgs.com rem includes rem 6 lives kernal rem

If i can add this code, how much "breathing space" would i have? Sincerely, Open Source Pong Quote Link to comment Share on other sites More sharing options...
+Random Terrain Posted October 28, 2008 Share Posted October 28, 2008 If you're talking about space for your code and you use Visual batari Basic, the Information Pane tells you how much space is left after compiling. If you run out of room, you can use bankswitching. If you're talking about using too many cycles, the info under Timing on the following page tells you how you can use Stella to make sure you're not using too many cycles: http://www.randomterrain.com/atari-2600-me...nds.html#timing Quote Link to comment Share on other sites More sharing options...
