  1. It works if you only want to play games that DON'T require Pokey or Yamaha chips (which is most games). Just do a google search for what they're. If you don't care about any games that require them, then you don't need them.
  2. Maybe not related or helpful but I had to add ferrite cores to the PSU where it meets the console, the power connector that attaches to the Dragonfly cart & to the A/V cable at both ends. Otherwise with this cart I would get a lot of interference that I didn't have with Concerto cart or official carts. 7800 seems A/V seems very sensitive.
  3. I bought that cable new (I didn't make it). That cable was probably based off an official one that are impossible to find. Atari ST uses FAT12 I think while your files may be using FAT16 (which only works with ROM upgrades or newer versions)? Maybe I could send what test files I have on my USB that work with my 520ST. Maybe this thread helps https://github.com/keirf/FlashFloppy/issues/232#issuecomment-711482366
  4. Ok I've mapped the cable. This cable works perfect for me. External link: https://archive.org/details/atari-st-external-cable
  5. I now have a working cable. I can map out all PINs for you later today after work or this weekend (this really needs to be on the web [I'll probably upload it on arcive.org too]). Just hold off for a little and I'll try to get that info for you.
  6. It has no partition. You need to right-click on the "unallocated" space and create a FAT32 partition. It should also ask you to assign a drive letter. If it does not correctly assign a drive letter right click on the partition and click "Change Drive Letter and Paths" and set one. * If you still have issues use a different SD card reader or different USB port. * Make sure you eject the SD card before pulling it out. * After you eject, make sure you unplug the USB cable and not just the SD card as Windows can get goofy if you don't on some readers. EDIT: looks like you got it work. Posted this before reading other comments.
  7. Right-Click on the "Start" button and open "Disk Management" This shows what partitions are on different drives.
  8. The issue was the "MOS Technology R6532" RIOT chip. Seems like both the R6532P & R6532AP will work.
  9. I cleaned cartage port & the removable chips with 99% isopropyl alcohol (first thing I did). The voltage regulator is producing 5v & 10v is being fed into it. I will clean again to be sure but stuff wasn't super dirty. I will also see if my Sears 2600 Telegames system chips can be used to confirm if the VCS has bad a RIOT chip etc.
  10. Have an Atari VCS 6-switch that will work fine for 1-sec (literally) then just go into some failed state. <<< EXAMPLES >>> Turn on system & I'll see a good screen 1 second later get this. Same kind of thing with a different game (and every other game I've tried so far) Anyone know what this might be? FYI I replaced 4.7uf-32v caps & 2200uf-16v cap. No change. I also tried replacing transistor in RF module but that didn't help.
  11. Awesome! I'm in the US. Are these shipping from Sweden? EDIT: Never mind I see confirmation email. Yes they are
  12. I had an Amiga ship from Poland and it took their government 2-3 months before releasing it to the US. So it might depend on where its shipping to. Russia also since COVID takes months for anything to get here (I ordered Famicom Lightgun).
  13. Yes with two .a78 roms labeled inside the zip. * Rampage (USA) (Doesn't work, bad header).a78 [sounds like this had no header which seems wrong for its file ext as you said] * Rampage (Works with potential graphic glitches).A78
  14. It ran then this graphics glitch started to happen less than a minute into gameplay. Also tried another rom & got this screen. Hit fire & it gets stuck at 90% on this rom.
  15. I bought this PSU which had one but still needed to add an extra ferrite core on PSU & some other lines. https://www.amazon.com/gp/product/B07QV8CCJ5 Got these ferrite cores which worked well for me in case others in same boat as me. https://www.amazon.com/gp/product/B07CWCSNW9 Can tuning get off on 7800? I wonder if its something I should double check on my system.
  16. So you have the purple PCB? So people with green PCBs and POKEY installed haven't had firmware upgrade issues?
  17. Got my ferrite cores. Put them on both ends of video cable, power supply (which already had a small one) & the power line between cart and console system (which made the most difference). Much cleaner image now & I'll get a better power adapter later.
  18. http://www.best-electronics-ca.com If you read back in comment though it sounds like you should hold off on installing POKEY until a later firmware update though. Also read back in comments to find out what SD cards have worked for people if you have trouble there.
  19. I'll try some others and see. Ok thanks, I'll order one & give it a try. Good idea to try if the cart doesn't have any electrical reason that could cause issues?
  20. Awesome POKEY works great. Cart working good overall. One thing I notice is the cart does add some video signal noise I don't have with other carts.
  21. Will possible future firmware updates be published here or is there an external URL to keep track of for that?
  22. Ugg silly me. Just blanked that existed. k tnx.
  23. Ok thanks. Did I miss this in the forums or you get that from external / other URL? Wondering if firmware update will only be listed here or some other site as well.
  24. Just got the cart today. What is the cart input power requirements? Volts & Amps? Also what is the power supply polarity? Are there diodes to protect against this if DC voltage is reversed?
