  1. Pong Music Demo from the BCC#18 Party in Berlin recompiles the byte code for the soundtrack on every level! There were some errors during playback on the live stream, here is a 10 minute video of the C64 and Atari 2600 Supercharger versions showing the AI composing new sound tracks. Which pieces do you like best in the video? How it works: Music is mathematical. A complementary algorithm changes frequencies, tempo and instrument definitions based on the existing musical score. The algorithm is then called recursively against each set of outputs (new songs) created. The Atari 2600 Supercharger makes dynamic code recompilation possible like on the Commodore 64 by replacing ROM with RAM. PongMusicdemo.bin pongmusicdemo.prg Playing the demo: To play the demo push up to enter player mode, push down to resume demo mode. You can let the demo keep playing and hear new songs for hours from the AI!
  2. The Atari 2600 beat the C64 at the Fjälldata demo party in Sweden Yesterday! Both machines were running the same demo Breakout Pet Factory B-Side. The C64 version features PETSCII graphics extensions and all 16 colors scrolling on screen. The Atari 2600 version has a Blues Soundtrack that may have helped it beat the C64 as the Fjälldata party is a music centric festival. Here is the Atari 2600 version for the SuperCharger with the WAV file: brkoutpfbside_Atari_SuperCharger.bin brkoutpfbside_Atari_SuperCharger.wav And a CBS RAM Format version for the Atari Flashback Portable and 2600+ : brkoutpfbside_CBS_RAM.bin You can download the C64 version from csdb. I will be releasing an upgraded version of SuperCharger BASIC for the C64 with Dynamic Color RAM support like the demo presently.
  3. I've added color support to the Atari 2600 emulator for the Commodore 64. Here's a screenshot of Gate Crasher Jazz Improv, my 10 line BASIC entry for the 2024 BASIC 10 Liner contest. Features two algorithms for Jazz improv, you have to make it thru the gauntlet to unlock the second algorithm and multicolor mode. I'll be releasing an updated version of the emulator with Atari Flashback BASIC support in addition to Supercharger BASIC prior to the March contest. Hope C64 fans are encouraged to enter the 10 liner contest with this fun BASIC! Download the game and the10 line BASIC program listing here from CSDB: https://csdb.dk/release/?id=238874 Video playthru with Jazz improv soundtracks and amazing color bloom Fx and artifacting on my classic JVC Television and 1982 breadbox with a 6581 R? SID and with RF over NTSC: real video unretouched How do you feel about the screenshot and the video shot on classic hardware and CRT? Is it fair to use classic Television and RF instead of Composite or S-Video the C64 natively supports? Many people had an ordinary color TV connected to their Home Computers in the 80's. Some sceners touch up their retro productions with 256 colors or more on modern hardware. We can do cool stuff with NTSC over RF too, the visuals are retro tricked out like my computer art contest entry from the 80's: That's a black and white image.
  4. I remember an editorial that made the salient observation we began coding less efficiently when 16K became the standard.
  5. Interesting PC-2 BASIC shows the entire 24K free with no RAM reserved.
  6. Learn the C64 architecture first - this is a great place to start: C64 Programmer's Reference Guide.pdf (classiccmp.org) I think the guide was expanded to include the C128 later on. The C128 mode is interesting particularly the enhanced BASIC and built in Editor/Assembler and Dissembler in ROM. Here is an educational video from 8-bit show and tell using the Assembler and Dissembler to find compatibility differences between the C64 and C128:
  7. Very cool ARMSID has analog filter support. It looks like a very close replacement. I read the spec sheet and this jumped out at me: Emulation of OSC3 and ENV3 registers (little delay, approximately 16 clocks of the C64 bus). The SID engine in this Christmas demo manipulates OSC3 and ENV3 rapidly I wonder if there are changes in sound reproduction: I notice differences between VICE using the 6581 resid engine and the 6581 SID in my Commodore 64. Both sound good but have differences particularly after a few minutes.
  8. I have not tried ARMSID yet. If I do I will run it through the diagnostic program. This is helpful to see if the analog filters work. DeepSID and the resid engine in VICE are highly accurate but there are differences even between the different models of the SID.
  9. The Kawari is a very interesting replacement for being able to switch between PAL and NTSC. It's still a C64 and has some extra functionality with the kawari. ARMSID has the opposite effect, it's still a C64 with a loss of some functionality. If the SID chip works you should put it back in and test it against the ARMSID with SID diagnostic software to see what you are missing.
  10. Christmas Inertia For the Atari 2600 and Commodore 64 Christmas Inertia is a fast-paced demo and game where you pick up friends in different zones. Each zone has different inertia pulling you in different directions making it challenging to pick friends up. If you prefer to watch the demo the AI can pick up friends for you! xmasinertia.bin xmasinertia.prg Design Written in Atari SuperCharger BASIC using graphics commands. Three Display Lists are created using the ASCII art virtual world drawn in the program listing. The Display Lists split the screen up to create Windows on the virtual world. Each Window has a separate camera view. Create Display List Games and Demos Display List Windows are familiar to Atari Home Computer programmers but new for the Atari 2600 and Commodore 64. Programming Display Lists are limited only by your own imagination. Download SuperCharger BASIC with Display List graphics commands for the Atari 2600 and Commodore 64 from http://RelationalFramework.com Christmas Inertia is featured as an Interactive User Mode Demo in the 2023 Christmas Demo stream contest and the 2023 CSDB Christmas competitions.
  11. Blues on Atari Sounds best on a Heavy sixer or four switch. Compatible with all Atari consoles including the Flashback Portable.
  12. Very cool. I just downloaded Dancing Feats and will try it out. It sounds pretty good in this Jam session:
  13. You are on the right track! If you wish to use the compiler from the command line it will always compile the program "program.txt". I recommend using the PowerShell ISE (already installed on windows) to run the compiler. It will compile any .txt or .bas program you also have open in the ISE, you should be able to compile any of the sample programs or create a new one.
  14. You might want to checkout SuperCharger Disk Extended BASIC as an option for building your large Berzerk sequel. This dev tool has GUI options for drawing screens and sprites and a tracker sequencer for the musical score and sound effects. It's designed for modular development like Audacity/Activision uses in their fat carts so you could fit all the rooms in your design and share variables between modules. I used it to design this Berzerk sequel with a large scrolling morphing board where characters slip through the edges of walls and shoot through them with environmentally unsafe weapons that bounce back to kill the wrong person and wreak havoc on the surroundings!
  15. Are there any new Blues compositions or existing covers on the Atari? Ballblaster/BallBlazer has algorithmic Jazz improv that is missing from the C64 version. The SID is a phenomenal chip but the Atari may have a richer sound for blues and Jazz.
