  1. HHGTTG FTW! You know, flying isn't that hard. Just throw yourself at the ground and miss. One of my favorites! (not an exact quote)
  2. The idea is that mode 10 is shifted half a wide pixel in relation to mode 9. Interleaving these modes gives the illusion of having 160 pixels wide, instead of just 80. Mode 9 lines use all the luminances. Mode 10 lines have the colors set to 0, 1, 3, 5, 7, 9, 11, 13, 15 (eight luminances and black) You can increase the illusion by using a flicker mode (it's not interlacing) by switching between screens that either start with mode 9, or with mode 10. Especially at 50Hz (PAL) it is not that easy on the eyes IMHO. About the half wide pixel shift, this results in a zig-zag edge on the left and right side. You can mask them by putting a black player or missile in front of the edges.
  3. If you change the background color of graphics 9, you change the hue of all the luminances.
  4. I recognize the change in wanting to play games. Sometimes I go months without gaming, and suddenly I find myself firing up my SNES with Super Turrican (real hardeware) and try to match my unofficial world record of 302K points Or The Last Of Us on PS3 to finally beat it in normal mode (I only managed easy mode BITD). Have been playing it for weeks now, every night. Four times easy, three times normal, and now I'm trying hard mode After that I'll probably not touch a game console in six months As for Atari hardware, I still have to install a Sophia DVI in my Atari. Just can't be arsed to do it atm Edit: My SNES Super Turrican records are 295000 for PAL, real hardware and real cart, and 303600 for NTSC on emulation. On an almost perfect run, I can't get the 50Hz score much higher. Never thought there would be that kind of a difference between 50 and 60Hz.
  5. There. That's the solution. Comparing all the dumps of the same pattern is trivial Good luck!
  6. I remember my dad and I typing in all the pages of MLX hexadecimal data. With CRC checks. Supposedly. After several long nights of either my dad reading and me typing, or vice versa, we finally had it typed in. And, .... it didn't work. That was very disappointing. A few months later I acquired a disk copy, which did work, and it was my favorite word processor at the time.
  7. Brrr, inline uploaded videos on AA really hog my browser (latest Firefox). Anyway, nice work! I could not make out if you do per pattern compression (AUDC/AUDF) or still full stream? Per pattern compression could be problematic. I thought of an edge case. If you play patterns 1, 3, 2, 3, pattern three is not necessarily exactly the same. If either pattern 1 or 2 leaves a note playing when it enters pattern 3, and it's a different note, or no note at all, pattern 3 is not the same.
  8. From the command line, try this: cd ~ find . -iname '*.rom'
  9. You could use PLA caramel color, or PLA wood filament, to get the same look. Another option is to print a mold and fill it with recycled cardboard. Like this: https://www.instructables.com/Recycle-Cardboard-Into-Anything-With-3D-Printing/ HTH, HAND
  10. I think you don't need any loop detection anymore. Just LZSS compress each pattern, and play them according to the song data. Loops are done through the song lines. And each pattern is only compressed once, instead of each time it is heard in the background. No worries. You are doing great stuff
  11. The main thing is repeating patterns. Like, my Lullaby interpretation will compress pretty good. But Procrastinate probably a lot less, as it are basically three songs in one. I'm aiming for at least four effects and music progressing from one song/effect to the other. I have a few songs in mind that could work well with the RMT player (which in itself is a form of compression), but probably not so much with the LZSS player. Rubber 🦆 is always useful I'm a big fan of https://en.wikipedia.org/wiki/Release_early,_release_often I might not be the proper tester/user at this moment, but others might be. Like emkay, miker, synthpopalooza, makery, etc... Something I'd like to see in the future is better MIDI input. Right now it is step by step, but it would be cool if you can just loop a song line, and set MIDI record to a certain pattern and then play your bass line, or chords. Or even record to a certain column of the song list, and improvise cool synth solos that span more than four bars Also, a mixture of LZSS and a song player. Each pattern could be LZSS compressed separately, and then played in the right order according to the RMT song data. That might be a good compromise between LZSS and a plain RMT player.
  12. I'm not in a hurry yet, as SV2K22 is many moons in the future, but what I would like is all the cool stuff you showed in videos, like all the tuning stuff and easy use of sawtooths, and then export a stripped RMT file, a header file with the options (un)set, and then assemble a minimal player. For a 16kB entry, which will hopefully sport four to six effects, and lasts around three minutes, it is not feasible to use the LZSS player. It uses less cycles per frame, but a lot of memory for 180 seconds of music.
  13. From a demo/game perspective where space is sometimes limited, it would still be nice to have a 6502 player. Do you plan a release shortly? I would really like to play with all the tuning options and create a new tune for SV2K22.
  14. This. If this works, but external real cartridges don't, there is a problem at the cartridge port or the lines on the PCB.
