Thank you all for your input on my last "un-numbered" Ship version. Tennessee Carmel-Vellieux wrote: >This is pretty neat...

I added something like this... but a bit better. It's true that you can't uncomment the mentioned lines in the last version. That was exactly the reason why I commented them... :-P And now from Glenn Saunders: >It's highly unusual for a game this preliminary to have had so much >attention lavished on the music, however.

I hope it is better now, but maybe it still can be improved. And finally, from Piero Cavina: >I did it, I couln't resist :-) >Here's SHIP 1.5, the whole kernel has been reworked, now it works drawing >the ship in groups of 4 scanlines, plus from 1 to 3 final scalines.. well, >you must look at the code to understand this, as the result isn't very >different.

OK, this is yet another version of my ship demo, and, yes it's got a version number. No big improvements, but fed by the input I got today: 1. Better sounding music (for Glenn, and of course for Jim) 2. Piero's new kernal with water surface flashing routine 3. Gradually fading shadow of the ship 4. Improved colors - I didn't read the 2600 documentation carefully. I learned now that the lum values range from 0 to E, leaving out Bit 0, not 0 to 7 leaving out Bit 3. You can read the full credits in the source code. With love (and still many things to learn and improve) Kurt Woloch
