  1. Ah, sorry, I didn't realise that was there. My apologies.
  2. Hi Karl. Someone messaged me a bit before you from the UK - if he doesn't take it though, you're next in line for sure.
  3. Will do this for £100 including postage to the UK if anyone is interested.
  4. I'm selling my Dragonfly if anyone is interested. Burgundy (red), Pokey Max, YM2151 module, and 5.5/2.1 plug cable. I'm in the UK but will post to Europe or the US on the understanding that all shipping fees will be paid by the buyer, and I won't be responsible for any customs fees / taxes that may be levied. PM me if interested.

  8. Here's something interesting. I was trying to diagnose another of my PAL 7800s that has absolutely screwed TIA sound. It's had a composite mod, same board as my other one. Now, as part of testing that, I swapped over the MARIAs (just to confirm that was working in the second machine), and early tests (it could change with warm-up etc.) show that Pole Position II plays with no crashes, and no graphics artefacts. Originally, the one that was in place when crashes occurred was this one: 8922BV V8861 VF2085A And the one that I replaced it with, which seems to work, is this one: 9221BV 228841 VF2085B Strangely, though, in the second machine, Pole Position II also seems to run OK, so there's definitely combinations that do or don't work with Dragonfly.
  9. Do you mean the Atari logo on the case? It's embossed (all of my 7800s are IIRC). Audio: would you mind sending me a private message with an image so that I can see what you describe? Just conscious of not wanting to muddy the waters of this thread unless you think other people will find it useful? I have a couple of other PAL machines with different mods in, so I'll check the DF with them when I get the chance, too.
  10. Of course, I understand about the resistors and the pots on the Dragonfly board - I was just observing that on my PAL 7800, if I DON'T have the 47k resistor, TIA/POKEY balance is no good. My NTSC one doesn't need a resistor added though, the sound is OK. With the 47K in my PAL, TIA/POKEY sound balance is good with the regular cart of Commando, but not with Dragonfly. Board is C300633-001 REV C. Pictures attached. Ignore the temporary resistor work So for me, the Ballblazer ROM works fine on my DF (at least for about 10 minutes - didn't test longer! Pole Position II ROM on DF will fail every time, usually after less than a minute of playing. Graphic glitches start to appear, then the screen will either go mostly green, or some other garbled GFX, then crash completely. With this exact 7800 I used to have problems with Ms Pac Man, exhibiting similar graphic issues as you mention with your homebrew Pac Man cart, and like you, they would go away once warmed up. I also powered the 7800 and DF both from the same PSU, and each from different (good quality) ones to rule a power issue out. And by the way, I'm NOT blaming Dragonfly, or saying there's a problem with it - I think there are enough of us now with various issues that suggest PAL 7800s are problematic, for some reason.
  11. Received my Dragonfly, and just gave it a quick test. On my PAL 7800 (I'm in the UK), some games will crash after a short while, but not always at the same time. I use Pole Position II and Ninja Golf as tests. Also, sound balance between TIA and POKEY isn't great, with POKEY being louder than TIA. I have a composite mod board in this machine, and have a 47K resistor joining R32 and R33 - that addresses sound balance with actual carts. Turning the POKEY down doesn't alter this behaviour. I notice the comments from @-^CrossBow^- about mod boards, but rather than this just being a sound issue, the games crash completely. On my NTSC 7800 which uses the same mod board, I have no crashing problems, and all sound balances are fine!
  12. Just read through this whole thread with interest as my Dragonfly should be here any day now. I'm in the UK, and will be using a centre negative PSU (because of space and efficiency reasons!) so my plan is to split that, then reverse the cables (thus polarity) for the one to the Dragonfly. I've also got multiple PAL machines, all with composite mods, but of different kinds. And one NTSC with a composite mod. It'll be interesting to see how it works with both.
  13. Some interesting opinions in this thread, but an awful lot of arguing, too! I think an aspect that has been missed except for only a couple of people mentioning it, is geography. AA is a very US-centric site and store (and that's not a criticism, just an observation). I'm in the UK, and import costs are high from the US. They're high enough that a physical cart for a game that you're interested in (as opposed to dead-set on getting) becomes a difficult prospect to sell to yourself. Itch.io (along with other indie publishers' own sites) provides an excellent platform for those of us that are into multiple systems, particularly the 8-bit home micros we grew up with. I regularly pay £5-£10 ($7-$14) for brand-new C64 digital downloads, for example. I've bought some physical tapes and discs of new games, too, but generally, I prefer digital as I have mass-storage solutions for most of my systems, and limited space in my house that I share with the rest of my family! I don't pirate like I did back in the teenage Amiga days, and I can't justify spending fortunes on new physical releases. That's not to say there's not value in them, or they're not worth it, just when there's so much competition on disposable income choices have to be made. For example, I'd like to buy BeefDrop for 7800 (the TIA version). With shipping, import fees and handling, you're looking at almost $80 for an unboxed version. That's just not going to be viable for many people. As someone who has a Dragonfly on the way for 7800 I'd love to be able to buy some of the HB releases I like the look of. None of us are entitled to be able to buy them digitally, it would just be nice if I could, and as a result there are many that I'll probably never get to play, but that's OK, and no different to any other entertainment medium. If developers want to sell their games digitally (and that's the key, again, we're not entitled to have them do so), the markets are out there. Like any side-hustle, work also needs to be put into marketing those games. If you're not efficiently getting the word out there, then your game won't sell many copies, digital or physical, so comparisons to physical sales on AA are tricky to maintain, it's a site with a long history, and huge user base.
  14. Please could I reserve one: Burgundy With Pokeymax With additional 5.5/2.1 cable Thanks!
