  1. The VERA SD card interface is for SDHC, so the capacity must be over 2GB, which means for practical purposes the minimum is 4GB as SDHC cards with a smaller capacity basically don't exist. The maximum for SDHC is 32GB.
  2. Cost, schmost. If I'm going to have a retro-themed drive enclosure, it must be STATE OF THE ART!
  3. I would like there to be an embedded OLED display instead of the red label, and it would show a tape reel rolling up as you fill it with data. And empty drive would look like a tape rewound to the beginning of that side. A full drive looks like the tape is ready to flip.
  4. Pre-YouTube, I have used Final Cut Pro (for Mac) and Adobe Premiere (for Windows), but now I stick to my guns and produce content using only Free Open-Source Software, including my host OS: Ubuntu Linux 20 LTS. I used to use OpenEdit, but it was not very dependable, and I've had much better results using Kdenlive, which comes with the Ubuntu Studio distro. I wouldn't want to make a feature film with it, but it's Good Enough For YouTube.
  5. The X16 shows up, but that's not really fair. Which classic machine will come out ahead?
  6. This is a very odd activity for a middle school class. Was this curriculum made for this grade level? The juxtaposition of a coloring activity combined with a though exercise on a concept they don't really understand yet is baffling. Maybe a discussion on ethics would be a better activity.
  7. The COLOR command in BASIC is actually even simpler. You just use the foreground color for the first argument and the background color for the second -- no need to combine them into a single hex byte. This lets you use the first 16 colors (0-15) of the palette for either argument: This is perfectly good for just doing a text-based adventure, but if you want to get into having something more than just a running console, you'll want to get into VPOKE-ing character and color codes.
  8. It may not be possible to have a louder triangle wave without clipping, and then it's not really a triangle wave. A max volume square or sawtooth wave is going to be VERY loud, so the answer may just be to ease off on the PSG volume for them. Of course, we will also have to see what this means for mixing the other sound sources.
  9. That's an impressively bad design.
  10. No, I just use direct manipulation of VRAM. The Kernal routines are limited, and not terribly useful unless you are doing something exactly like what they were written for, and the VRAM interface is really just as simple to use. Here's the video:
  11. That was definitely the highlight of the games I've discovered with this console. Never knew it existed, but it's a really good game! I think if it hadn't been shoehorned into the Street Fighter franchise, it might have fared better, as it's such a completely different kind of game.
  12. I did a couple livestreams playing around more with the "620 in 1" NES Classic clone, and edited them into a single video: If you want to see the original, unedited streams, they are on my second channel: https://www.youtube.com/channel/UCNPJDAcKcAUYfemAMwqa56g
  13. I bought one (well, actually two) of those NES Classic knock-offs from Wish out of sheer morbid curiosity. Turns out to not be quite as horrible as I had feared (which was really bad), as captured in my latest video:
  14. Target whichever one you are more comfortable with. Both are going to be on the X16. The PSG is going to give you something more like the C64 SID (but not quite) while the YM2151 will give you something like the AdLib or Sound Blaster FM synthesis (but not quite). The PSG can be programmed much more easily, but you can use commercial software (namely Deflemask) as a tracker for the YM2151 and get all the register writes and timing that you need to do. I made videos about both so you can see how they work: PSG: YM2151: I will also be making a video on how to use the PCM in the future, as well.
  15. Congrats! Hopefully it goes better for you than.... Leisure Suit Larry?
  16. I just happened to have these lying around:
  17. I'm not a professional educator, but I do actually make a living as a technology communicator, which has also driven my side gig as a creator of programming tutorials on YouTube. Please feel free to use my X16 tutorial series for any folks looking to go the extra mile (or kilometer, depending on location) and learn 65C02 assembly language: I have also dabbled in mixing C with assembly language:
  18. Oops, forgot Episode 3: And now, Episode 4 is out:
  19. He tried to add it, but the flux capacitor kept leaking.
  20. The last prototype had a YM2151 and both PSG and PCM in the VERA, just like the emulator. The SAA1099 is no longer on it, and was never emulated, anyway. Kevin made no mention of any changes to the sound for the third prototype, so it looks pretty set right now. The FAQ is a bit ambiguous, mostly due to staleness, just like the 8BG videos are very old now, the last coming out right after the first prototype was up and running. The only difference in the sound since the R38 emulator is a change to the addresses for using the YM2151, which is reflected in the most recent commit to the repo, which will eventually R39.
  21. I've had success using Krita for the actual drawing part, and then exporting it to Gimp to do the palette conversion.
