roland p Posted November 25, 2008 Share Posted November 25, 2008 But I'm really getting out of ROM space. Lots of code is generated with macro's. Is it OK to change some macro's into subroutines, push some variables to the stack and call the subroutines with JSR? In general there's nothing wrong with changing macros into subroutines...except that it will eat CPU cycles due to the JSR/RTSes and the pushes and pops. Here's a document that shows how to do f8 bankswitching: http://www.qotile.net/minidig/docs/2600_ad..._prog_guide.txt It's not too hard...partitioning the code is really the hardest part. Ben Thanks, I'll check it out. I'll go that route now, I can always optimise the code afterwards if I want to. Quote Link to comment Share on other sites More sharing options...
Mirage Posted November 25, 2008 Share Posted November 25, 2008 Been following this since the start, and just want to express my appreciation (and amazement). Truly, this is incredible. Never would have guessed a 2600 could get even this far towards this goal. Please keep it up, and finish the game if possible (and it appears to be possible?) Incredible. 1 Quote Link to comment Share on other sites More sharing options...

Ben Hi, I'm now trying to bankswitch. I've split my source into small parts so it's easy to move them around now. The code in the document you're refering to is in the $1000-$1FFF range. My modified hello-world is in the $F000-$FFFF range (I don't know why). When I change my orgs from $FXXX to $1XXX and I compile the thing, things are really slowing down in the emulator. Any idea what is going wrong? source.zip Edited November 26, 2008 by roland p Quote Link to comment Share on other sites More sharing options...

Thomas Jentzsch Posted November 27, 2008 Share Posted November 27, 2008 ACCELERATION is just a constant, so the address mode will be ignored. Quote Link to comment Share on other sites More sharing options...

roland p Posted December 5, 2008 Share Posted December 5, 2008 (edited) Major update! implemented for both players: - non linear friction - brakes - bouncing on all 4 borders (was 3) - max speed - added bankswitching, 8Kb - full internal 16bit calculations now my brain hurts There are some small visual glithces, I did not take care of that this time. The code is very bloated too, but at least the functionality is there. ballblazer.bin source.zip Edited December 5, 2008 by roland p Quote Link to comment Share on other sites More sharing options...

Thomas Jentzsch Posted December 5, 2008 Share Posted December 5, 2008 Excellent! Did you limit the maximum speed by hand or does it automatically get limited by the friction? Quote Link to comment Share on other sites More sharing options...

roland p Posted December 5, 2008 Share Posted December 5, 2008 Excellent! Did you limit the maximum speed by hand or does it automatically get limited by the friction? Just by hand. For each axis there are 3 states: accelleration to max speed ór friction ór brake Quote Link to comment Share on other sites More sharing options...
+Random Terrain Posted December 5, 2008 Share Posted December 5, 2008 Now we don't go faster than the speed of light! Much better. Is it just me or is the maximum speed set a little too low? If I remember correctly, maximum speed is a little faster than that. Quote Link to comment Share on other sites More sharing options...
roland p Posted December 5, 2008 Share Posted December 5, 2008 Now we don't go faster than the speed of light! Much better. Is it just me or is the maximum speed set a little too low? Could be, parameters can be easily tweaked now. I did not compare it to the real ballblazer yet. Quote Link to comment Share on other sites More sharing options...

+remowilliams Posted December 6, 2008 Share Posted December 6, 2008 Simply mindblowing to see that on the 2600! The movement and reaction feels very good. As far as max speed, either the playfield is too large or the max speed is too slow. At least by my guestimation of 'feel' vs the A8.
