Thanks for The Response Zebidee

Use the EDID Luke!

That photo is Taken with EDID Emulation Turned on

On my Win7 cabs I'd have 20-30 video modes installed, and that includes super resolutions and a few weird ones for other games and emulators.

I dropped the Resolutions down to 86 to be compatible with Hyperspin, though if I just delete All modes in Driver, Swichrez obviously can't find a compatible mode, Flags the Error then will load in 256x224 (V) 60.00000000 Hz but with a Horizontal Orientation without issues. If I try to adjust Rotate in the mame.ini it switches it but upside down and really really small. (most likely can't find a compatible resolution)


If I Install 30 Modes Like in your Install (also tried 20), It loads it up and grabs that 2560x256P Mode as posted in previous Post With Same Identical Problem. (you stated you have Super Resolutions as well) "Zig Zag"? Is that what the issue is known as?

I never bother with cut-paste modelines from ArcadeOSD, and just edit the monitor presets in monitor.ini instead.

I am using a custom Modeline as well, I used ArcadeOSD in the 640*480 Resolution, then I went to adjust the Horizontal Settings, got the geometry to what looked correct, wrote down the numbers and pasted them over the arcade 15.7 default modes saved, reset and turned EDID Emulation back on.

These Are my current Settings:
Standard Resolution", "4.3" crt_range0 15625-16200, 49.50-65.00, 4.767, 4.767, 6.544, 0.096, 0.191, 1.084, 0, 0, 192, 288, 448, 576

Now before you jump on me for the H Front Porch and Synch, I know those numbers look strange, I got them from ArcadeOSD, and the resolution on the screen still has some overscan but completely readable, and here's the thing I have generated those numbers so many damn times from different ArcadeOSD Preset resolutions and repeated this and I can't honestly figure out what is what there is no firm pattern or correlation that I'm recognizing here when I adjust. (They seem to just jump all over the place) No matter how hard I try at the vertical settings in the geometry screen, I can never get that lined up, they seem to be proportionate with the Horizontal Settings yet its like they scale much larger than my screen, and I have been curious about the 288, 448 numbers on the end of that mode line. (ActiveLinesLimit &  VirtualLinesLimit). Yet I have adjusted those numbers as well and no difference
[Edit] If I am mistaken your statement above, I have also Tried the Standard Settings available without switching anything, and the issue still persists though it is not as bad, meaning the zig Zag is Smaller, though the overscan at the top missing Scores ect is still present, pushing more towards thinking this has something to do with the Vertical lines available on the screen.

 and yes I have this page pulled up (http://geedorah.com/eiusdemmodi/forum/viewtopic.php?id=46) and this specifically stated   Contrary to the horizontal case, vertical amplitude is usually not adjustable by tweaking these settings, only centering is possible in most cases.

Though I do have the Service Menu open and Can adjust and willing to deal with wonky picture to an extent, I have no idea how to approach that Zig Zag, let alone understand "Why" is it there?

GM is designed to just work, once you have it setup right. Most problems seem to occur because we think it must be more complicated than it really is.

Good point, I over think allot of things.

On your vertical games zigzag, that may just possibly be crappy sync from the cheap chinese box.

See attached photos, Same with wakabavideo box and the Chinese box. I honestly can't tell the difference between either of the boxes plugged in.

I've built a few MAME cabinets over the years, always with a regular desktop computer, but I just made an interesting discovery: a Chromecast with Google TV (a $30 Android TV gizmo) runs old classic 80s arcade games via MAME really well (with Mame4Droid and RetroARCH). I'm currently using a bluetooth XBox controller, which works but not having a 4-way joystick for games like Donkey Kong is a serious deal breaker, and that's the kind of games I want to use this setup for. So I'm thinking about building a little portable controller.

Out of the box the Chromecast doesn't have any USB ports, and though it is possible to add them with a dongle I'd rather just keep things wireless. Does anyone happen to have a recommendation for a Bluetooth keyboard or joystick encoder?

And any recommendations for a joystick that can be switched between 4-way and 8-way without opening the controller enclosure?

Or maybe I'm overthinking it and there's already a good off the shelf wireless controller that people recommend? I see the 8bitdo stuff recommended pretty often, but there doesn't appear to be a 4-way version.

Windows 7 is hard-limited to 120 custom video modes. Sounds harsh, but it is more than enough. You shouldn't need anywhere near 120.

On my Win7 cabs I'd have 20-30 video modes installed, and that includes super resolutions and a few weird ones for other games and emulators.

It is in your best interests to have fewer video modes installed, because every time switchres (part of Groovymame) goes through them all to work out which mode is best, it takes longer with more modes.

I never bother with cut-paste modelines from ArcadeOSD, and just edit the monitor presets in monitor.ini instead. You can do it via the GUI in VMMaker. Once you get it right, every mode will be auto-generated with the right geometry. Test with desktop res and a few well-known games. It is easy to tweak the values and regenerate/install the modes again, as many times as you like, until you get it right. You don't even have to re-boot in Win7 (like we used to do with XP). So easy!

You mean the stuff in the attached image?  ( how to insert image into the message? )

The dongle then outputs RGBS via a female DB15HD (VGA) plug, pushing composite sync on pin 13.

I've got an AdvanceMame setup with direct connection from the PC VGA to an Hantarex Polo 15KHz connector (see attachment) with all wires connected (RGB hsync vsync ground). Your dongle could be used in my setup? I see pin 13 AND 14 in the wiring, are they both pushed on or only 13 (composite sync)?

Hands up for this amazing project.
Open source is always better, and acknowledging other people's works is a well-mannered move.
Thank you for your work and your time.
 

That’s just crazy enough to work.  I will take calipers to a few HuCards this weekend and report thickness results.

Sorry to be a bother, but was wondering If I could get a bit more help in "defining" the issue I'm Seeing on the Screen it happens with the Vertical Games only, I have been reading all sorts of things thinking this was called screen tearing, but I don't think that's right cause I have followed a couple things from the Offical CRT_Emudriver forum discussion docs and none of that is panning out, so I think this must have a different name, and I just need to know what to search for, and if Possible where the issue typically comes from, that would greatly help me in my research to get to the bottom of the issue.

A trick used before surface mount became dominant.  Extend the PCB pads, bend the IC leads out 90 degrees, set onto the new pads and solder.  Surface mount style.  No leads protruding through the PCB.
