I added you to the list.

You can use the dragonfly like this, nothing bad will happen.
-
Is the plus inside and minus outside? Is the plug really 5.5/2.1mm and not 5.5/2.5mm? Do you have an electrical meter to measure the voltage in the plug?
-
Select "force power" mode or turn off the logo in the Menu.
-
After turning on the cartridge and waiting for a while, you can turn on the console, the logo will appear. But remember to activate the logo in the Menu after updating to version 1.07, it is in the penultimate position (before "Developer").

You can do it with any hex editor, just delete the first 128 bytes and save as .bin.

I was resampling VGM files but at 50/60Hz the main instruments weren't too bad but timing for percussion was out. So I used the YM IRQ and resampled at a higher frequency. Attached is the VGM for Shinobi playing at about 2kHz (you can change tracks by pressing the trigger).
You quickly revised my assurance
For people who are unable to recreate Shinobi, I include audio samples, this is great!

8 hours ago, DrVenkman said:HOWEVER, and this is a bug report for @rj1307 when he's feeling better and can look into it: the game seems to ignore the difficulty switch settings; as folks may or may not know, the two switches actually matter for how BBCQ actually plays - they control the movement, jumping and firing button assignments, or whether UP on a stick or gamepad jumps.
Dragonfly does not have any effect on things like the operation of the difficulty switches. I cannot imagine how I could block their operation?

(This is NTSC).
These colors look very strange, they should look like the ones @ZeroPage Homebrew showed.

11 hours ago, DrVenkman said:Well, the thing I'm getting at is that the same binary I have on my card (direct from Bob's thread and copied to a folder I created on my card called \PacManPlus with all my faves from Bob) *did* work with Yamaha sound before I updated my Dragonfly to 1.06. I'm wondering what changed with 1.06 that might have changed the way YM sound was detected/enabled in Bob's binary, and what's different with the binary Rafal provided for the \YM2151 folder.
With version 1.06, the correct header (according to its new version) is needed for the YM and Dual Pokey to work.
6 hours ago, -^CrossBow^- said:You have to enable the IRQ mode for Yamaha starting with 1.06 I believe. Bob's all in one file is what I have on mine and it was working on 1.06 once I made that change.
This is not true, no one is using the IRQ for YM yet.
5 hours ago, -^CrossBow^- said:The startup logo doesn't work on my 7800 it seems. All I get when I try this is a slow scrolling set of purple and green lines along the left 1/4 of the screen or so. But I can choose a game while that is happening and load it up and still play a game. So I'm pretty sure that is the startup logo I'm supposed to be seeing but isn't working proplery.
I confirm, this is my mistake. After the fixes it works on PAL consoles and it stopped working on NTSC. I will correct it.

Software update!
Changes: Addition of the startup logo + the ability to enable / disable it in the Menu.
After turning on the cartridge power, the graphics with the logo will be loaded automatically and the voltage for powering the console is given. If you start the console, the picture will be displayed until you select and approve the game to load. The graphics are not loaded from the file, they are loaded from the AVR memory.
After updating the software, set the new function in the Menu.
On my consoles, which are tweaked to auto-start, this works very nicely. This resolved the issue with the monitor turning off automatically after five minutes of inactivity

Thank you all for your kind words.
It's not too bad so far (I can compare it to the average flu), but I don't feel like doing anything.

I updated the list .
ATTENTION!
Unfortunately, starting today I am quarantining due to a positive test for Covid, so I will resume further shipments in about two weeks.

Software update!
Changes: The backlight of the LCD will turn on automatically when the console is turned off.Hardware update!
The modification will reset Yamaha when changing the game.
It cannot be used for serial numbers from 136 upwards and for serial number 112!Connect any of the points marked with the red arrow
piece of wire, with a point on the YM board.

It can be done

16 hours ago, Hastor said:@rj1307 I'm not sure if it is possible for the cart to detect when the system isn't drawing power, but if it is, I'd recommend not turning off the screen unless the system is on, and have it on any time the system is off, period, so it isn't easy to accidentally leave the cart on when you're done.
Do you want the LCD to light up when the console is turned off?
-
No, only this reset is added.

As soon as I test it for myself, I'll make a modification instruction.

Not at the moment. Altera Max Plus does not support the USB programmer, and so far I have not found a way to convert to Altera Quartus (Quartus claims that the EPM7128 chip used has not enough resources!).

No, it is for .a78 files.

12 hours ago, Hastor said:I have noticed, and maybe this is normal, if I turn off the console, but not the Dragonfly, while PMC XM is running, it will keep playing the same note until I turn off the DF.
This is because Yamaha is not reset and remembers the last command.
From serial number 136, Dragonfly has a revised CPLD program and a Yamaha reset added. I can provide a modified version of the program, but uploading it to Altera requires the ByteBlaster LPT programmer, a computer with a parallel port and Altera Max Plus software.It is also hardware modifiable, it would require a soldering iron and a piece of thin wire.

In the attachment I am sending files for the SD card, maybe it will help.

This is what I introduced the extra delay in the latest firmware for, you can adjust it in the Menu
1 hour ago, Hastor said:Or does the cart turn off the power to prevent damage to the cart while flashing, meaning I could mess that up if powering them separately?
No, you won't break the cartridge like this.

"Dragonfly" my version of the Atari 7800 SD cartridge
in Atari 7800
Posted
I'm not keeping exact statistics, but I estimate about 10% of the cartridges without a Pokey Max (but the vast majority of people wrote that they have their own Pokey chip) and about 15% without a Yamaha. I produced 206 cartridges.
