>But isn't the 6507 reset vector at $FFFC? Sorry, I think that you're >wrong.. look inside any .BIN 2600 file. Yes, you are right. $FFFA is the (nonexistant) NMI vector. I mixed that up, sorry! But I already have a new theory. :-) Due to the fact, that your program is so short and so many bytes are the same value, Stella07 can't detect the BIN type right. It assumes a Superchip BIN, if the first 256 bytes are the same value. Maybe it has a bug in that routine. If you save the following as STELLA.VCS into your STELLA directory, both demos should work fine: ===Begin of STELLA.VCS=============================================== VCS-Script (begin ;; ;; Properties for Cavtron ;; (if (member Cartridge.Image '("CAVTRON.BIN" "cavtron.bin")) (begin (set! Cartridge.Name "Cavtron") (set! Cartridge.Type "4K"))) ;; ;; Properties for Christmas Demo 01 ;; (if (member Cartridge.Image '("CHRDEM01.BIN" "chrdem01.bin")) (begin (set! Cartridge.Name "Christmas Demo 01") (set! Cartridge.Type "4K"))) ) ===End of STELLA.VCS====================================================== >wow! i've taken that code straight from Oystron, so if what you're saying >is correct, I could save 4 bytes... > >I think it would be nice if one could turn on and off the background music >in Oystron. I'm going to see if I can find the space.. Your game is so compact, that you could probably add two more levels in those four bytes. :-) Ciao, Eckhard Stolberg -- Stella list is Administered by krishna@xxxxxxxxxxxx <Glenn Saunders> Archives (includes files) at http://www.biglist.com/lists/stella/archives/ Unsub & more at http://www.biglist.com/lists/stella/stella.html +-shameless plugs-------------------------------------------------------+ | Stella documentary at http://www.primenet.com/~krishna | | Nick's VCS links via http://www.primenet.com/~nickb/atariprg.htm | | Write the best game, win framed autographs of famous Atari alumni!! | +-----------------------------------------------------------------------+
