• demotool musicdisk SEGA Genesis/Mega Drive MDMOD Player by Titan [web]
• PAL or NTSC does not matter - if you add a region switch to your MD, it will only change the video standard, not the internal clock rates; the internal player runs independent of the video output so it'll sound exactly the same.
  
  MDs that were originally PAL and those that were originally NTSC however have slightly different master clock rates and so pitch/speed will be slightly different between both, just like a record spinning a little bit faster/slower. The number of samples per song tick will still be the same for both of course so songs that use long samples with vocals etc. exactly synced to song ticks it will still work fine in either case.
  
  I did not add a PAL/NTSC check for adjusting song pitch since many MDs are region modded these days and while you can detect the current region, it's impossible to detect the master clock frequency. Any auto adjustment could thus end up going in the wrong direction.

• The teletext demo many sceners have been waiting for, and you nailed it perfectly!
  
  Special thanks for the write-up.

  19-byte 🏳️‍🌈 - no more LOAD ERROR but this "waves" a bit, couldn't find a way of stabilizing this without increasing its size:
  
  
  Code: * = $7c SEI loop: SRE $ECBE,X AND $EDA9,X STA $D010,Y LAX $D012 ASL TAY BVC loop
  
  
  Hex: 7C 00 78 5F BE EC 3D A9 ED 99 10 D0 AF 12 D0 0A A8 50 F0
  
  1st run: starts with A=$52, X=$FF, Y=$01. Will end up writing $20 to $D011 to disable the screen.
  
  Further runs: ASL / TAY ensures that Y is always even (-> will never write $D011 again) and writes go to the border register every 32 rasterlines.

• 23 byte version, might or might not be rule-bending:
  
  
  Code: * = $7c SEI loop: LDA $D012 AND #$E0 TAX STA $D011,X LDY $A355,X SRE $A651,Y STA $D020 BNE loop
  
  
  Hex: 7c 00 78 ad 12 d0 29 e0 aa 9d 11 d0 bc 55 a3 5b 51 a6 8d 20 d0 d0 ec
  
  Load normally, ignore the load error (it overwrites system variables in the zeropage which confuses the system), start with RUN.
  
  This abuses the ROM as a source of pseudo randomness for computing the intended color from the current rasterline. Plus a few tweaks for stabilizing the timing so it does not flicker.

• That's some crazy use of boolean logic! And very good presentation too. This is one of those few cases that really got me wondering "how on earth did they do it?"
