I have a Pandora box connected to my arcade cabinet with an arcade monitor. It works good however I wanted to take it out and power it up with a power supply and connect to a hdmi tv or vga pc.
When I put 5v and 12v to the jamma connector it powers on but does not display. I have tried various resolution settings and can only get it to work in my cabinet. I have benched another brand box with no issues doing this. I must have someting wrong . I have two of these model Pandora boxs and both do the same. Anyone have a clue what I am doing wrong ?

Hi Toasty,

I tried the vive tracker as a light gun route myself and used the precompiled vive controller as a mouse pointer as well. I ended up getting this gun (Hyperkin Hyper Blaster) to attach the vive tracker to:

It did all work in the end but it was a lot of mucking around. I ended up getting an off the shelf solution that uses 4 IR emitters around the TV / Monitor.

help. I don't get the output. thanks!

virtuo is okay.

early models have issues with black spots appearing on the LCD panels due to a manufacturing defect. later models have no panel issues... but some issues with bad caps on the  backlight inverters. newer ones have LED backlit panels and have issues with the caps going bad on the LVDS board. the later 2 being fixable... the spots, not at all other than panel replacement. good luck finding a panel to replace it....it's a weird size and wasn't available for long.

the computer is decent. it's output audio via regular headphone jacks so no messing around there. you will need a "red" DI box to convert the audio from the computer to the amp (amp accepts balanced audio over ethernet...the IO board does this so you'll have to sub the red DI box to do this.)

the card reader is worthless as it's been disabled due to new PCI credit card processing rules rules... making it non-compliant.

the stand should have woofers built into it... it should also have some satellite speakers attached to either side as well.

Sounds like I should keep the Angelina then, I really don't have an use for the stand. Im sending the acceptors today to a dealer that would update them to a regular non touchtunes firmware in order for me to use them as 12v pulse type.  Thats all that is left before I put it in a place to work.
The guy wants 600 DLLs for the virtuo wich is a great deal, but I don't have that kind a money right now.
Im hoping for a Christmas miracle on may hehehe

I have noticed that my MAME starts having occasional small hiccups when it has been running for a few hours. I'm running regular MAME 0.263.

The hiccups are like small freezes, just a fraction of a second, maybe just like a frame or two. It seems totally random, not related to any input or anything that's going on i the game, and with 5-30 seconds random intervals. I've had this in several versions of MAME now, and it occurs in any game/rom, so reckon it's most likely not MAME itself causing this, rather some other stuff interfering with it. But I'm not quite sure, because if I restart MAME, the hiccups go away.

I'm on Win10 64 bit, running an i5-3350 and a GTX1050 with Gsync, which is very, very smooth when these hiccups don't occur. Vsync, triple buffer etc are off. I have turned off all power saving stuff I can find, but I'm a bit lost here. If there was something obviously wrong with my setup, the probem would probably be constant and more severe. But this seems to build up in magnitude as long as MAME is running, and disappears at once when it's restarted. Could resemble a memory leak, but I kind of doubt that MAME has had that kind of problem for several releases?

Any ideas what this could be, and how to fix it?

Hi Jay, how is going the project? Has you advanced on the board, I am very excited about it!

Something odd I noticed, is that in mame when viewing the "Control Inputs" service menu and turning the wheel clockwise, I see the hexadecimal number decrease, not increase...

Sounds like the optical data lines (A and B) are swapped, which reverses the axis.
- It could be your setup (not likely), settings, the connections in MAME (also not likely), or the axis reversal setting in MAME's Analog menu.

Sounds good to me, great stuff

I'm still catching up. I've managed to get mame built from github and I can run hard drivin' (compact) and airborne. I've just not hacked the code yet (But I think that's what I need to do to get a feel for what is happening). I'll start experimenting with my wheel at the weekend.

Something that has always bugged me with the compact roms, is that it is not possible (yet, I think) to successfully calibrate the wheel using the service menu. I went and did some reading/investigation, trying to work out what values to expect (When viewing the "Control Inputs" service menu) from a successfully calibrated wheel. I didn't get very far. Thought I'd post my notes as they might be of interest/help:-

Code: [Select]

Compact harddrivin service manual (HDC_TM-329_2nd.pdf):
041787-02 Steering Encoder Disk.
043807-02 Centering Encoder Disk.

HDC_TM-329_2nd.pdf, From the "Control Inputs" service menu:
As you turn the steering wheel clockwise, the hexadecimal number should increase and change to zero once every turn.
As you turn the wheel counterclockwise, the number should decrease. Everytime the steering wheel passes the center position,
the words center edge should change from blue to green.

HDC_TM-329_2nd.pdf, from a section near the end about installing a new encoder wheel:
Install the steering wheel with the center spoke down. Make sure the single hole on the centering disk is between the opitcal reader on the centering
PCB so the steering wheel will be correctly centered.

From the Race Drivin' Compact Manual, for the Main Board Memory Map, it says:
OPTO: Optical Steering Wheel Reader
400000 (R) OPTORD Read the Optical Counter
404000 (W) OPTORES Reset the Optical Counter
408000 (W) CENRES Reset the Optical Centre Flag

I found a picture of a 041787-02 Steering Encoder Disk, and counted 72 holes. Based on this, I don't think we should see a steering value (When viewing the "Control Inputs" service menu) reported that exceeds 72 (Or maybe 144 if we are counting teeth passing as well has holes). Thus, when turning clockwise you'll see 0 increase to 72 then back to 0 etc... When turning anticlockwise you'll see 72 decrease 0 then back to 72 etc... In mame, I think we see values much greater than 72, this might cause strangeness. I think I'll try and hack things so that I force these 'ideal' values to occur at calibration.

Something odd I noticed, is that in mame when viewing the "Control Inputs" service menu and turning the wheel clockwise, I see the hexadecimal number decrease, not increase...

just want to say ive been following this thread for quite a while.

I have a spare RPI 4 8gb, and it's getting this ASAP.

now i've gotta build a baby dk cab too - really amazing work. I am head over heels for your project.

You mentioned your health and single malt - hope everything is ok and you take care of yourself, tons of old nerds need you now more than ever!

Thanks!
Health is good.  Still drink single malt whisky but also ran a Marathon earlier in the month. 

I put a lot of time into DKAFE recently, extending it to include console and computer ports, remakes and hacks of Donkey Kong.  Quick launching and playable with arcade controls.   I made an add-on pack available which includes over another 100 DK versions.  Windows build is out now and being tested.  If all good then I'll get this onto Pi soon.

DKAFE is built as an application and can potentially be ran independently of my image in a different environment.  I'll take a look at the link you posted re: CRTpi project and see if I can offer any help or advice. 

I'll post more info about my DKAFE progress here soon.
