GBS-8200 won't save horizontal/vertical position/size

[clhug]

Or more precisely, it won't APPLY the custom saved horizontal and vertical position and saved settings on power-up.

I posted in a different forum about this and they suggested I post here.

I just bought one of these GBS-8200 boards to replace a dead CRT with an LCD monitor in an old arcade cabinet (Arkanoid II). I ordered off Amazon, one of the many on there that I'm sure are probably Chinese knock-offs, but I did look for one that had many reviews (and mostly good reviews), vs. one that had very few or no reviews, and it wasn't the cheapest one, in hopes that would indicate one that was mostly dependable. (Though yes, I know there are such things as fake reviews too, so reviews are no guarantee.)

I am still within my return period for Amazon for another few days, so if the consensus is that I have a faulty card, I can still return it.

It works great in general, nice color, stable picture, with one exception. In short, it doesn't apply my custom horizontal and vertical position and size settings after it's powered off and back on.

In more detail...

Upon first connection and power up, the picture doesn't quite fill the entire monitor screen. It's about an inch short vertically and 2 or 3 inches short horizontally.

I can use the Geometry settings on the 8200 board to adjust the horizontal and vertical size and position to make it fill the screen. But as soon as the board loses power (when I turn off or unplug the game cabinet), the next time I turn on the game the picture reverts to the original size and position.

At first I thought it wasn't saving the settings. Upon further testing I confirmed that it does save all other settings; picture (brightness, contrast, etc.), resolution, language. It's only the Geometry settings (H/V size/position) that are an issue.

BUT upon further investigation, I discovered that the board DOES save the custom numerical values of the Geometry settings. I.e., even though the picture has reverted to its original size and position on the monitor screen, when I go into the board's Geometry settings, the numerical values of each setting ARE what I left them at when I adjusted it and before I powered off the game.

I can then select any individual Geometry setting and change it up or down by a single increment, and the picture suddenly jumps to the position and size corresponding to that setting.

So it is apparently saving the H/V position/size settings in its memory, it's just not applying them upon power-up.

Is this a known thing with these cards? Is there a "trick" to getting it to work? Or do I likely have a defective card?

Thank you.

I posted this question on 3 different forums and didn't get an answer on any of them. BUT I managed to solve it myself, totally by accident, so I wanted to post back in case anyone else runs into this, hopefully it helps them.

All I did was press the "Input" button (the left one) repeatedly to rotate through the inputs. When it got back to the input I was using, the picture suddenly jumped to the custom Geometry settings I had made, and it stayed that way from then on, after many power cycles.

I doubt this is by design, but I'm glad there was a fix for it.

I'm not sure it matters, but I'm using the 6-pin wiring harness that comes with the board for the video input signal.

Just making sure, you have the following set correctly in arduino ide when compiling and uploading the software?

Flash size to "4MB (FS:1MB OTA:~1019KB)".

Wait, are you using a GBS-Control modded GBS-8200 or just a stock 8200? I have a GBS-Control modded one and Im not sure if I dont have a similar issue, need to re-check. BTW, if you havent done the GBS-Control mod, by all means please consider doing so if you have any soldering skills. Fun project with incredible results. I love it.

Lol, I didnt even consider that this could be an unmodded gbs. :p By all means, all problems will be solved by modding it and using the CFW.

Yes, unmodded. Except for this one issue, it worked fine for what I needed it for. I did look at the control mod as a possible solution, and might have done it if I hadn't found any other solution, but since it otherwise worked well enough unmodded I didn't want to put the additional effort into it if I didn't have to.
