    Cosine Systems has released my game, Chiller 2!  This is dedicated to Cosine's C&C, T.M.R who is still in hospital at the time of release.  I desperately wanted him to play test and approve before release and feel bad about releasing it before, but this needs to go out now.

     

    Download includes game on a .d64 and .tap file plus all the source code and work files for graphics and music.

     

    Download here: https://csdb.dk/release/index.php?id=198231

     

    Merry Christmas!

    What I mean "offscreen" as in outside the normal 200 scanline area.

     

    Porting to Atari - certain tricks on either machine are sort of irrelevant on the other.

    Sprites in the border - we have that by default through you can't normally have PMG outside the 240 scanline normal area.  But with an Antic bug exploit you can (though many TVs will never show them).

     

    Scrolling/DMA delay stuff - no need for it on Atari as scrolling and screen addresses can be done on a per line basis.

     

    There was no need to display sprites in the border for the demo, the design didn't call for it.

     

    Although I can now just about code some 6502, everything else you just mentioned on Atari is alien to me but sounds fascinating which is why I would like to learn via T.M.R.  I've done some composing on POKEY for T.M.R and love the sound it generates, so would love to explore A8 more.

    Nicely done.

    I asssume it's opening up the border but from what I saw no sprites get displayed offscreen?

    The top/bottom borders are open, yes.

     

    Not sure what you mean about sprites 'off-screen'?  There are sprites being recycled down the screen in various IRQ's, the get well message composed of 5 sprites (or was it 6, can't remember even though I drew them and coded the thing!), the Cosine copyright logo made of 8 sprites and the main scroller has a 'dissolve' either side of the screen done using 2 sprites.

     

    There are 3 character sets on screen to do the logo at top, the wibbly wobbly thing in the middle and then the text at the bottom.

     

    The music was written for an 8580 SID, but the code will detect and modify the filter tables if an older 6581 SID is used.  Thanks Odie!

     

    All standard fair I think.  The download on CSDb contains the (fairly well commented) source and all data files, because I believe in sharing.

     

    One day I hope T.M.R can teach me how to port my code to run on A8 machines...  Get well soon T.M.R...

    Let's get the TOPIC clearly labelled... I had no idea this was about TMR....

     

    Thanks for doing this @aNdy_v

     

     

    The demo will be C64 only at the moment; I can code 6502 and write POKEY music, but I don't know enough about A8 architecture to release for Atari 8bit yet.  I need T.M.R to get better so he can teach me!

     

    I originally missed this thread because of the topic title also...

     

    I'm releasing the demo tomorrow, so any last minute messages to T.M.R, please post below!

    I'd have said 'Keep Fighting Jason! And don't forget your special moves!'

     

    I messaged you about Jason weeks ago on E64. At that point I was just querying if you had heard from him, I suspected he had it, I got it too. I seem to have been incredibly lucky though.

    I'm so sorry, I seem to have missed those messages on E64.  Apologies :(

     

    I can add your above message if you like, or do you want to add more?

    I'm a member of Cosine with T.M.R (my C64 6502 coding mentor) and I've written a simple C64 demo to cheer him up (hopefully) while he is frustrated in ICU.

     

    I have some memory left for messages in the scroller, so if you want a message added please leave a post below with a short message (couple of sentences max.) and the handle/name you want assigned to it.  First come first served.
