Anyone able to find a VGA to HDMI converter that is compatible with the funky VGA signal from the Chihiro? This converter, https://www.amazon.com/Adapter-FOINNEX-Converter-Connecting-HDTV-Male/dp/B071SHJ1S3, is so far tested not working and may buy different converters.

This is for a Ghost Squad machine and I would rather not spend a lot of money nor do a lot of ridiculous mods. Currently using an LCD with no VGA port that remembers its power state. Most LCD monitors do not have a VGA port installed nowofdays compared to about 5-10 years ago.

Also I tried with this and dont run on my 2013 HDTV (best input lag at this time):
Before DCHDMI mod I used it for my dreamcast and run perfectly. It's seems Chihiro's VGA output is 522p or something like this. Maybe if your HDTV is most recent accept it.
Scart xbox + OSSC = 480p output. Scart xbox and OSSC is plig and play ...not "ridiculous mod"...

OSSC costs a lot of money.
You have to think of things from an arcade operator standpoint because I have this machine in the back of an arcade waiting to go on the floor. Most operators would rather not remove the AVIP cable when it comes to replacing the CRT with an LCD.

So the only converter I have that accepts the Chihiro VGA signal is the GBS 8200 style HDMI converter. Although it requires a crap load of adjustments, the picture looks more than acceptable. Eventually I may consider installing GBS Control for this converter.

The Monoprice vga to hdmi converter works well for me, it’s high quality as well and it seems to work with weird resolutions. The Namco system 246/256 spit out weird VGA resolutions which certain monitors don’t like and this converter plays well with it. It only works with 31khz resolutions and not 15khz, for that, the ossc is a better choice. I’ll link both of them here:

The OSSC is very tempting at this point so I may save up for that in the long run. Looks to be a better price value than the Monoprice VGA to HDMI. Also, some Namco System 246/256 games only run at CGA instead of VGA making the OSSC the better option either way for any 246/256 owners. May as well suggest this for Namco System 23 since it seems to handle interlaced video well.

Yes, I tested the Namco System 23 and other arcade boards with the ossc and it was much better than the GBS-8200. The colors were much better and the image was much sharper. The only issue is incompatibility with certain displays and certain video capture devices and the ossc has little to no frame buffer for interlaced video.Still a nice choice over other more cheaper or super expensive alternatives.
Here is a picture of my tekken 2 pcb using the OSSC.
Edit: the ossc works fine with the Elgato Camlink 4K for video capture. Looks amazing! I have a still from a video I made. Have a

If anyone is reading this. I bought an OSSC not too long ago and it arrived. I can CONFIRM the native VGA signal from the Chihiro base board DOES work with the OSSC although adjustments will have to be made via remote. My next test will be the D-Terminal component port to see if I can get a better picture out of this port.
Update 5/23/2021. Using the base board's VGA port is NOT the best idea due to the picture being heavily zoomed. I'm going to have to go with nonosto's suggestion to get a SCART cable (ordered one right away). I may have to change some dip switch settings on the filter board before hand to prevent an error involving the wrong scan settings from occurring but could be wrong. I myself didn't know what the heck SCART even was to begin with as that cable plugs into the avip port (let alone that type of cable exists in the first place). Fingers crossed I am able to get a good picture that isn't horribly zoomed.
Even if you flip the dips the boot.id in the games will force segaboot to check the settings. I did find the byte in boot.id which can fix this but you'll need to patch every game if you intend to change the dips. 0x2C into boot.id change to 0xFF

Definitely use GBSControl!

Hi,
I'm sorry but I didn't understand quite well your post.
Did you successfully try Monoprice VGA2HDMI on Chihiro or was it only with Namco systems ?

It should work with the chihiro systems but I highly recommend the ossc. The Monoprice vga to hdmi converter only works with 480p 31khz resolutions unlike the ossc.

OK, thank you for your repply.
Are there games outputting something else than 480p@60Hz on Chihiro ?
I am currently using GBS-8200 to play Chihiro so I don't exactly know which resolution gets into the GBS.
The thing is : I have tried 4 different VGA2HDMI converters unsuccessfully with Chihiro and I don't want to get another brand unless I have some positive reports of it working with Chihiro, I guess you understand.
I do have questions though about Chihiro's D-Terminal output.
If anyone can answer those, that would be really appreciated.
1/ Do all games both display on VGA output and D-Terminal one or does it need to play with dipswitches ?
2/ Is the D-terminal output signal more standard than the VGA one ? Are there success stories of Chihiro D-Terminal ==> D-Terminal to component cable ==> Component to HDMI box, we know of ?
If so, I would maybe go for the D-Terminal output instead of the VGA one that gets too difficult to display on HDMI monitors without image quality loss (my GBS setup works but with non neglectable quality loss)

Tbh, I would say either hack your GBS-8200 and convert it GBS control (look it up) or get an OSSC for the best image quality through HDMI. I have played around with a modded Xbox with chihiro games and they all seem to output 480p60, I’m not sure about real hardware. The Monoprice converter I got is good but not great, it does have some color issues (blacks tend to look grey) and you can’t do anything about it.
