Open Source C64 Demos
Given recent discussions on this, I thought it could be good to collate the various open-source demos in one place..?
I've added several demos that I've worked on (with many other GP'ers of course) here:-
https://github.com/RobertTroughton/C64Demo-PublicReleases
(currently includes Delirious 11, X Marks the Spot, The Dive, Memento Mori, Christmas Megademo and No Bounds .. though we'll of course add more later)
And Bitbreaker/Performers just made the Next Level source public:
https://github.com/bboxy/next-level
Also note that I have the https://www.c64demo.com domain where I plan to blog about all sorts of coding stuff .. hopefully once I finally release Sabre Wulf Remastered I'll have more time to do stuff there too.
I've also attached to each entry on CSDb a ZIP containing the current state of each source branch. That way, it's all hopefully better preserved. I strongly encourage others to think about that too - sometimes (or 99% of the time?) these links on CSDb become stale and stop working ......... |

Quoting jareth_2005@yahoo.comI am the of Pasm assembler and it comes with free demos.
https://github.com/pebmeister/Pasm
It ships with source for a grahics cartridge that adds the following commands to basic via wedge.
HFRECT - Hires filled rectangle
HLINE - Hires Line
HPLOT - Hires Point
HRECT - HiRes Rectangle
HGROFF - Hires grahics Off
HFCOL - Hires ForeColour
HBCOL - Hires BackColor
HCLS - Hires Clear Screen
HGR - Hires Grahics On
HCIR - Hires Circle
HFCIR - Hires Filled Circle
HBEZ - Hires Bezier Curve
HTEST - Test Comamnd for the cart
The graphics command set of plot, point, line, circle, and cuve added to BASIC look pretty cool, I'd like to see something written with this for the BASIC10Liner contest this March if your team could demo it there.
Those graphics extensions look like it should be possible to write an interesting game or demo in 10 lines of code with the wedge.
Are any sound commands added and is it possible to use the BASIC wedge without the cartridge? |

Hello!
In my 128 bytes intro New World OR'er [128 bytes] when plotting odd pixels (bits) I use some "magic bytes" from the ROM and RLA opcode, which helps me save 4 bytes (table of $80,$20,$08,$02 is useless now).
Source with comments I've just attached to release.

I censored jareth_2005's 10.000 rows of pasted code to make this thread readable and useful again. If you want the code jareth_2005@yahoo.com posted, ask him about it. |

the problem is with all this stuff certain folks want an advantage over others.. yer I saw reflex taking apart tmr's "thermal raster bars" part at x95.. it's bitter sweet many times.. and yer Jason found it a compliment they were hacking away with their AR6's back in the day.. as my dutchies will comment.. I may have been the worst for wear that weekend ;-) |

ooh yeah quiss this is great! very nice to be able to read through the code - but even after reading the code, i'm still at a loss as to what the original thought process behind this magic could have been! very impressive. |
