  1. Why do you use Go to line commands to go to the next line? E.g. 2A: Go to line 2B. Do you use them as delimiters?
  2. Very good! I like it a lot! And a lot of people won't even notice the missing key changes
  3. This how did it once in an experiment:
  4. And I did not specifically plan to participate myself, besides doing the base themes in RMT. Perhaps I'll improve it some over time, if I can find the motivation On YouTube, Spring responded: (emphasize is mine) So who knows how many plan on releasing their own version
  5. http://ftp.pigwa.net/stuff/collections/RK-DVD/Atari 800 Images und Files/Cartridges And Roms/System Roms/ Perhaps you can find one here? Lots of Omni* OS ROMs, Ramrod, and Fastmath. One is bound to contain the 2kB fastchip mathpack, no? Edit: Came across your previous thread: https://atariage.com/forums/topic/321264-atari-os-with-fastchip @Faicuai and @phaeron should be able to point you to the right OS ROM file with the fast chip math pack.
  6. Tying /HALT to high seems like a valid test. No ANTIC there to /HALT the CPU. This looks like a b0rked Sally. The address line capture makes no sense at all. There's almost a C0vFEFE in there
  7. My google-fu led me to these threads: I noted the difference between FastChip and Fast Chip.
  8. Electrocution also counts? I have electrocuted myself numerous times. First time when I was three. It's one of my oldest memories (but not the oldest).The family was moving to another home, and during the move I found some nails. Mom and dad were in the other room, so I tried if it would fit in a wall socket. It did. And was very painful. 50/50 chance, but I was lucky Not ten years ago, I opened up an old digital photo camera. I wanted to replace the IR filter by a visible light filter so you can take night vision photos. Most sensors respond to the IR spectrum, hence the original filter. So, I knew there were capacitors in there to hold charge for the flash light. Hence, I first flashed, and quickly turned off the camera. Removed batteries, etc... Little did I know. The capacitors were either charged very quickly, or only lost part of their charge. At a certain point, I touched both the + and - side of what I think was the flash capacitor with my pinky. By accident. 180-330V DC. I felt it up to my elbow. Not fun
  9. AFAIK Rastaconverter doesn't use the fifth player/missiles, so that could be used as a crosshair. About a game, one could have say 200 "rasta" lines, some stats on top, and bottom in character mode. Convert the image without using the players, so they are free to play pong on top of the image
  10. No, the key changes seem to follow group A (from the video). 3 themes times 8 bars equals 24 bars. And then a key change to +2 semitones and then to -2 relative to D minor. Note how that's 6 song lines per key change! (six patterns, times 4 bars per pattern, equals 24 bars)
  11. This is still valid, but... this is not. The key changes are also sort-of polyrhythmic. Key changes are every 24 bars/measures, not every 96 bars as I said before. That was wrong Even though the alignment of group A and B has a four times lower period. The key changes do align with the group A melodies, because 24 can be divided by 3. But 4, 8 and 16 cannot Edit: here's the ST version: https://www.youtube.com/watch?v=lCNMufnJCuk Here, within a theme, the instrument type is also varied. The first half, and the second half of a theme are not necessarily played with the same instrument.
  12. For sure! But he did ask. So there was some effort But it was merely the first meaning I read that made me wonder. The word 'undeserved'. But I get it now
  13. Yes. Load WAV file, convert to mono, resample to 15600 (Tracks->Resample), export as 8-bit WAV. Not sure if the resampler is a proper resampler, so best do a low pass filter on half the replay rate (7800Hz in this case) on the original WAV file and then reample to 15600.
  14. Yes, that's what I'm saying. They align after after 12 times 8 equals 96 bars. Then they modulate to Em for 96 bars, and then to Cm for 96 bars. That's what I meant by:
  15. Some more explanation of the RMT file patterns: $00 -> drum (note the two different snares) $01 -> bass $02 -> theme 1 (4 bars, play twice for full theme) $03 -> theme 2 (idem) $04 -> theme 3a $05 -> theme 3b $06 -> theme 4a $07 -> theme 4b $08 -> theme 5 (4 bars, play twice for full theme) $09 -> theme 6 (idem) ... $11 -> drum and bass combined Song: repeat drum and bass ad infinitum. Themes are played as follows: (A): 1 2 3 1 2 3 1 2 3 1 2 3 ^ ^ ^ ^ (B): 4 5 6 6 4 5 6 6 4 5 6 6 ^ ^ ^ The song is in the key of D minor. Once the patterns align again, the whole song transposes to the key of E minor (play all notes two semitones higher). After that is finished, it transposes to the key of C minor (play all notes 2 semitones lower in regard to the original D minor key). Then loop the whole song. I did not do that in the example file. It's up to the participant to copy and transpose the patterns. The ST version does not transpose the drums. The Amiga version does. It plays all samples 200 cents faster, or 200 cents slower, including the drum samples. The key of D minor are the same notes as the key of F major, but you start counting at a different note. Key of F major: F G A Bb C D E F Key of D minor: D E F G A Bb C D All themes have their own instrument already in the RMT file, but they are mostly the same dull distortion A with a basic volume envelope. Some hints to improve the instruments: Theme 3 chords are: D minor: D F A F major: F A C A minor: A C E C major: C E G This is the Amiga guitar line. Each chord is played three times in different inversions. It starts with the first inversion (root note on top), then the second inversion (root note in the middle), and then the base chord (start with the root note). Theme 2 and 5 are the same instrument type. Theme 6 is the bubbly sound Theme 4 is the increasingly bigger vibration and then slide up a little. I made it two patterns and two instruments. More like the C64 version, but you can add more instruments to slightly increase the vibrato depth, and use a portamento at the last note in pattern $07. I really recommend watching this video that Wrathchild pointed us to earlier: https://www.youtube.com/watch?v=n6I0ROSCWwA
