Did you get my message?

I also use adjustable and it works fine: https://allegro.pl/oferta/zasilacz-uniwersalny-kemot-urz1187-1500ma-3-12v-9084166650

I will try to introduce this option, but it will take a while.

That makes sense, @RevEng, could I ask you to post it?

There are free bits in the $ 035 header, you can use them. But it's not up to me.

If you run PMC_XM with the RAM function set to Force, the Yamaha module starts up and the YM potentiometer is adjusting properly. The PL and PR potentiometers will be inactive. If you run PMC_XM normally, without RAM, no potentiometer will react because it is a TIA sound. I have just checked it on unmodified PAL and NTSC consoles. Referring to the previous entry, if you want to turn down the POKEY sounds even more, you can replace the 22k resistors with 47k:

Also useful for Dragonfly. For FatSort, I use the command: sudo fatsort -c -n /dev/sdb1 your partition may be marked differently than sdb1.

And don't worry about it at all Dragonfly was not created for "fame" or to raise my prestige, but because I was pissed off because nothing was ready to buy. Neither CC2 nor Concerto were available. It was the same with AgaCart, I got bored of waiting for LynxSD forever. Please clarify, because I do not fully understand: is there a problem with the Pokey volume setting?

I am also surprised by the short circuit in the plug, I check all cables before shipping. Can you describe exactly what was the cause? I solder the wires to the pins.

I do not understand anything wrong, I try to dispel any doubts and if something is unclear, ask I just checked Santa Simon on the PAL console and it works, on ProSystem it won't start. I have no idea what version it is, all files are from @Trebor package. Also, I would like all files to be segregated into PAL, NTSC and those that work on both systems. But it's a lot of work, maybe someone will do it? Will you send me a file that works fine after disabling Dual Pokey? I'm curious about it.

Yes, the YM2151 is stereo, but in Dragonfly it is summed up into one channel. If someone wants to introduce an additional stereo sound socket, I will show where to connect with the wires. I will definitely not modify the project to add such a socket. They must be short so as not to catch on the PCB at the top, and at the bottom against the cartridge slot in the console. They are long enough to hold the housing together. You just have to be careful with the tightening force so as not to damage the thread in the plastic. One would have to wonder here. I wanted to maintain a uniform structure of the entire housing, if someone did not want this sticker, after removing it, the whole thing will look good. Printing this part on a smooth table is possible, but without a sticker it will look poor. As of today, I have about 50 housings printed, I would have to modernize them all. The sticker is printed on an ordinary inkjet printer, on self-adhesive photo paper. I can share her design so that anyone can print it if it gets damaged. I mentioned running the YM sound in PMC_XM in the manual, where I describe the Menu and the Force RAM parameter. PMC_XM checks for the presence of RAM before starting (although the game itself does not use it) to determine if the XM module is connected. If there is, it starts Yamaha, if not, it starts TIA. The header in the PMC_XM file is set to not use RAM, so the Force parameter was created to turn on the memory. Can you determine which demo had a problem with Dual Pokey enabled? This option unlocks a $ 440 address that is normally not used. Anyone can insert an SD card into the reader, connect to a computer and sort / add / delete files as they want, I see no reason for me to have to ask every person what they want on the card. Original games are divided into PAL and NTSC, but HB games are not, maybe someone will sort them into systems? IRQ is disabled by default, as of today nothing uses these interrupts.

I soldered the wires to the places where the signal from the left and right channels are not summed up yet and connected them to the laptop's audio input. For tests only. Black arrow - GND, red arrows - audio signals:

Here is the Outrun recorded in true STEREO. I was so curious how it sounds that I have led Dragonfly left and right channels independently. Outrun_stereo.ogg

My colleague @Eagle posted two files with music demos using Dual Pokey on the Polish forum. They are available for download in the attachment, designed for the PAL console. Here are the .ogg files ripped from real hardware: Outrun.ogg Acidjazzed.ogg Below are oscillograms showing the audio outputs from both Pokey: And here is the signal to switch to the second Pokey: Outrun.a78 acidjazzed.a78

Only in this thread. I did not notice such effects, it is rather the fault of the power supply used, do you have the opportunity to try on a different type?

Yes, in Dragonfly I use a plug printed on the printer and contacts like this: https://www.tme.com/us/en-us/details/hdp20-1662911/d-sub-plugs-and-sockets/te-connectivity/166291-1/ In addition, 0.5mm wires that I solder and not clamp to the contacts.

For starters, I suggest checking if the header is set correctly. Do you use banking?

Yes, should I add you to the list?

You will get it before spring I put together the cartridges every day, sometimes it's one piece, sometimes four. We are currently at number 33.

In the attachment I put the .stl files for the housing and power plugs, it may be useful to someone. Dragonfly_STL.zip

NTSC games run on PAL consoles may have graphics distortion, run at poor speed, or crash.

Tracking of each shipment and a link to the Polish carrier is provided in the first post. Unfortunately, it does not specify which carrier handles the shipment in your country.

Interesting topic, but definitely not now, I have too much work to do with the assembly of Dragonfly. Besides, I would have to have such a test console.

The PCBs have finally arrived and I can start assembly, just after the New Year, a dozen more people from the list will get a private message
