Thanks very much for the info and all your work! I knew that an expert with the skills and hardware can do it. Unfortunately it still doesn't work in MAME but probably it will run soon with all that info. The 2nd video is even more interesting. Most of the games have been dumped including the 4in1 M...

I mean the stuff that is still available like this one http://web.archive.org/web/20071025200435/http://www.bripro.com/low/gameking/index.php?page=video3 And the Graphics Editor must be very useful. The src is also available. I don't know if he actually owns the handheld itself. He should be able to...

5 months after Porchy dumped some of the games, we have a skeleton driver in MESS with some few new details. So work is going on. I wonder why he hadn't used all the tech infos from BriPro that is already known. Maybe someone will dump the system BIOS (including the 3 games) or try writing some home...

We don't know how the display is accessed, configured, or anything else BriPro gave very detailed infos about how the display works. http://web.archive.org/web/20071025064343/http://www.bripro.com/low/gameking/index.php?page=video The sound should be uncompressed maybe ADPCM. Of course some details...

I don't understand. How to start any other unknown emulator project? The person who dumped and connected it, knows the software, the game. And can test and compare it. Otherwise it won't be possible to write any emulator for unknown stuff. Or need for in-circuit testing? The ROM data consists of 650...

Now Porchy from JAMMArcade.net has dumped some games. He owns 13 games, looks like no multi carts. He used female (?) jumper wires to attach to the slot pins and 74HC4040. To me it doesn't look like if they are enough wires. And on the upper slot pins row he has 2 rows of jumpers attached, I wonder ...

I now made a simulation using openBOR about my favourite game galled Terminator what is a Double Dragon clone. Not completed yet, 1 level only. You have to sign up at chronocrash to download it from there. There is a fighting game what can be made using mugen. And the platformers can also be made qu...

I have obviously destroyed my dumping device. So that's the end. :cry: Someone said, I would need a connection to OE. I was pretty sure that this only can be pin 46 (S3). I put that to GND (using a resistor). After that the FTDI board wasn't recognized anymore. No COM port. Device Manager code 43 (U...

Yes, it's the same port. Uploading the sketch obviously worked (according to IDE and some lights flashing). I don't know how to correctly initialize the port. And I don't have experience with Arduino programming. As said I have copied the code from other projects. I changed "while Serial.availa...

I finally have attached all wires. Even without soldering. I bought thinner ones and plugged them into the slot behind the cart.

No data are displayed on the PC. I tried 57600 and 9600 baud.
Probably the code is wrong.

Thanks for your efforts. Music and sound must be taken from some other (famous games) like all the other ones. There's no sound hardware or sound chips on this system. Street Hero has same sound effects /speech but different music. So probably sound and music are from different games. Spectask has s...

My dumping project has to wait for a while. This sound is from the Gameking game Terminator which is a Double Dragon Clone. Most games are NES clones, music might be from SNES and can be from a completetly different genre. CPU is 6502 based. Does anybody know where this music and sound effects comin...

Thanks very much for this link. There are 2 or 3 in my region. One needs to pay an annual membership. Others seems to be universal meetings (and also have quite high fees). And one is more far away. But I will check them. Probably there are much more people with soldering skills in my neighborhood. ...

I give it up. Look to the photos and you see why. First the thin drilled wires often undrill and the tin hardly sticks. The tension and force of the other wires are too big. One soldered, 2 got loose. Either break off or get in contact with the tin of the neighboring pin or the iron. Then I tried it...

Soldering some of the thin floppy wires worked much better than thought and better than on the previous slot as this slot was soldered to the PCB and isn't new. Although it's very fragile and I don't know if I can manage 34 wires. Maybe I need 2 floppy cables for the 4 rows. The wiring construction ...
