DAPHNE

I had forgotten about this thread. I did manage to get Dexter working with these Data East PCBs.

Hi all, I work in an arcade where we have a Dragon's Lair machine running a Daphne board. The USB drive currently plugged into the board appears to have given up the ghost (can't even read from it using dd in Linux). I tried formatting a new USB drive as FAT32 in Windows and plugging it in with Dex...

If the pulse light isn't blinking, that could mean a loose connection between the Raspberry Pi and the Dexter PCB. http://www.youtube.com/watch?v=AixbT6OEm7c You might also want to try replacing Dexter's SD card as some people have had those fail after a few years. https://www.daphne-emu.com:9443/me...

I'm getting the following error when I start Dexter Manager with my Dexter USB drive is read: "Error when trying to scan disc image container header could not be read" I've removed all disc image files from the disc folder (thinking maybe one was corrupt) and I still get the same message....

For those following this thread, the problem was with the Dexter firmware. I issued a firmware update today with the bug fixed.

A few things to try... 1) When it has failed for you, while it is in the middle of doing the looping search attempt, try hitting the Dexter RESET button. It's located under the Raspberry Pi near the power jack. Report back with results. :) 2) Does the mach3/uvt boardset have a reset switch on it? If...

Is this the issue?

We're thinking to do this on Monday, the 25th of this month, starting between 12:30 and 1pm EST. Then we will need to wait for it to do it. Will we need to alert you when it happens? That works for me. I've got it on my calendar. If you wouldn't mind dropping a note when you've hooked it up, then I...

We installed dexter in a time traveler game, and it worked great for a while. Then we noticed it would start beeping after being on for a little bit, and customers couldn't play the game. We have it set on free play. We have to reboot it to get it working again. This happens several times a day, an...

Having an issue with Thayers Quest playing the disc image from start to end without any ability to input controls. Just comes on plays all the animations including every death scene and then goes black unitl you reboot it, and then it does same thing again. I had my tech install this board, but now...

Steve says: I am not sure where Dexter control begins and game control ends. I am getting imagery on the screen, so that must be coming from Dexter. Wondering why I could not control the game to start by firing trigger, I was left to confirm trigger signal at game diagnostics. Trigger fire, as well...

Steve says: Hi Matt: I installed the recently shipped Dexter installed in my MACH 3 arcade game. The game powers up properly. The game already had a pre-existing 110VAC plug inside, so the Xfmr power supply for dexter was plugged into that existing plug for simultaneous power up per dexter manual r...

I put a small adhesive heatsink on Pi CPU. I noticed when running the ALG multigame I built in our wherehouse when it was very hot and no AC, the video started glitching and slowing down. The Pi throttles clock speed if it gets hot I think. You can get small adhesive square heatsink at Mouser. This...

falsenorth wrote:Thanks. I think I might have it figured out. I was thrown off a little bit by Space Ace's dip switch numbering (0-7 = 1-8) and accidentally had some diagnostic or test mode on.

Ah yeah. That is indeed confusing. Glad you got that part sorted. Let us know if you have other issues.

I should add that I am very eager for you to be successful getting your game up and running. Every Dragon's Lair or Space Ace brought back from the dead is a win for all of us.

Thanks for the reply. I had already watched your troubleshooting videos. My problem is nothing that was covered in the basic troubleshooting. Maybe I'm just confused, but there didn't actually seem to be any troubleshooting in the intermediate troubleshooting video. It was just explaining that trou...

most likely that message that you saw was a "red herring". We can't know what problems your game might have since we are not omnipotent. However, we can discover whether the game is properly communicating with Dexter, which is a good starting point. Check out the videos I posted here: http...

Hey Matt, Thanks for the response. I shot Shaun an email, will see what he thinks. Any way of telling which rev. that board is from the pics? I certainly couldn't tell. I'll get those ROMS covered asap, though I'm likely going to pick up a Merlin DX in order to swap between DL/SA. Try http://www.dr...

Hi Dan! Thanks for posting here so we can help. Everything is up and connected via Dexter. Hurdle #1; I have no idea if my DL main board is supposed to be using the 7820, the LDV1000, or has the switch to go between the two. I know the Dexter is supposed to autodetect which it should be using, but i...

Cool, it’s no big deal, I am really excited to get to play the game! Anyway, so from what I understand for you to remote in I need to download Dexter manager correct? And set up a time and date with you to do it? Also, do you have any idea off hand why my game wouldn’t do the move beeps? I am just ...

The debug info is a problem with the license file. I must've overlooked this as i was preparing the unit. I can fix this for you remotely. Sorry about that!

The move beeps are generated by the game, not dexter.

I think Tony M. Victorino (aka Lord Victorino in these forums) has managed to get a separate TV hooked up to Dexter and reports that Dexter does seem to have enough output strength to drive this separate display. I haven't experimented with it myself. I think he used an RCA splitter, not that I can ...

Sorry for the inconvenience. Most likely, Windows has popped up another window (which might be hidden) saying that the drive has errors and needs to be scanned. Initiating this scanning process will put the drive back in read/write mode and you will be able to update using Dexter Manager. It seems l...

Hi, I have a Dexter board for Space Ace that is not lighting the led for power and is not getting pulse or selecting a laserdisc player type. Is there some troubleshooting I can do on the board to maybe determine cause or even fix the issue? Thanks! If the power LED does not light up, that could in...

Bumblebrow wrote:Wow, thanks for the detailed information! Can you tell me how to check my Dexters to see if they have the ground fix you mentioned in #1?

Almost everyone has a Dexter rev 3f which has the ground fix. The revision is printed on the bottom PCB near the reset button, underneath the raspberry pi.

27990117_10211168982649116_1648766376_o.jpg Several people have reported this error to me. If you see it, it's caused by a problem with Dexter's raspberry pi communicating with the inserted USB drive. To workaround it, just eject the USB drive and keep it near by. It is only needed for updates so y...

when the work for playng it with their beutifull colour under dexter is planning to begin?
thanks

I'm not sure. There doesn't seem to be much demand, frankly. I think other than you, only one other person has expressed interest to me.

awesome!
