- GBS-Control - My first attempt at a Review/Test video , follow along while i test my new Upscaler , i found a significant bug along the way and may help you out if you have similar problem, Wifi Disconnects randomly
This review is regarding The GBS control upscaler sold by aliexpress
this is based on ramas modification to a GBS8200 RGB upscaler for arcade machines .
he replaced the "brain" with a ESP32 and now this upscaler is in direct competition with the Framemmeister and OSSC (open source scan converter)
If you bought this or are going to buy this product this is the video for you ,
i bought this my self not sponsored

15khz option means that it works as downscaler. I have one of these variations called ODV GBS-C AIO, and it also work as downscaler.
Thanks for the video!
Muchas gracias por la reseña. La mayoría de mis consolas tienen la salida por video compuesto porque lo que no me valdría este dispositivo. Terminé por comprarme un Retroscaler 2x, bastante simple, funciona el NES y el Megadrive y casi no se nota el lag.
oye como conectaste por RGB o SCART? yo no puedo hechar a andar el rgb... Saludos.
Hello, it is an interesting project but I have some questions. In my opinion, the reason for using a scaler is not only to enlarge the image but also to generate an image (on LED TVs) that looks like the one We see on a CRT. I know this scaler can perform some type of scanline simulation. If this simulation is done well it can be interesting (that is, not only adding a black line but correctly simulating the blurring of the "pixels")... BUT, I AM MORE INTERESTED in DITHERING replication. The SEGA Megadrive/Genesis consoles exploited the presence of dithering in their composite video output to achieve transparency effects or an apparent palette expansion. From the same megadrive connector we can extract an RGB signal (scart) that has greater clarity, but loses the dithering, which is taken into account and used to generate visual effects. Does this scaler have a setting that allow us to recreate the dithering?. Using this scaler, do megadrive games look like they do on a CRT? Do we have transparencies and color gradients again?
Hey, great video!
I got mine yesterday and I'm trying to do downscaling via the Saturn cable (Saturn to SCART to be precise), as source I'm using the Steam Deck. Yesterday I tried going into the GBS-C via a HDMI -> RCA converter but got a black screen, probably due to the issue that the yellow cable is actually sync (I still got audio though).
Using a RCA -> SCART Adapter in addition still results in a black screen sadly.
Can a HDMI -> VGA converter solve this issue?
Yes i think so . Hdmi can not output rca directly but it can transfer Vga(RGB) signal
Hello bro, I've adquired this recently, I've some questions. When you turn it on a red led is on? Have you tried snes thought scart? Dud you read any kind of documentation? I'm having issues with the image and config if it. I'm confused
HI Bro,
yes the LED should light up Red and the Small LCD should display text (resolution/ presset /misc),Yes i have tried Scart cable for the SNES and it works great (new video coming soon with all my consoles😁), i did not read any documentation but you could follow the information in the GBS control wiki should be the same as the one you got :
ramapcsx2.github.io/gbs-control/
It worked for you?
Did the gbs saved your last settings?
Yes it has saved all my settings even my custom presets, only setting that doesn't seam to save is resolution, will check if a firmware update fixes this , will update you when i know @@mysticauls
@@RetroUpgradeTks!!
hey I have scart RGB cable for ps1-2 can I use it? and all I need is HDMI-HDMI cable for my tv to work? I have flat TV 1080p
Yes exactly should work . It's a little picky with some signals but if you just disconnect from the WiFi with the gbsc most problems go away.
I actually got my cables last week and they work fin on PS2/3
Is this the same stuff that can be used to downscale hd/480p games to 240p for crt gaming? does it add any lag too? I'm looking into buying a nice CRT monitor to use with older gen systems but also with system like the PS3 (480p the lowest res it support) and downscale the games to 240p assuming it wont add any lag.
actually the downscaling on this board is probably the best i have ever seen 0 lag, 0 artifacts, just works , there is a video by Retro RGB that test this with some nice equipment ( if you want a in-depth test)
Only 8 ms from 480p to 240p, half frame. From 480i is slower
@@adangonzalez-ji5kp, @RetroUpgrade thanks for the information. My last question before I order the GBS Control; how do I connect it to a CRT monitor that only use S-Video?
I don't think the GBS control can do that natively. But you can use RGB to svideo Converter from de scart or Saturn output. Here is a example there are loadswww.cpcwiki.eu/index.php/RGB_SVideo
@@sonyx5332 you need an RGBS over VGA to S-Video transcoder like the one from retrocastle
Hi. I have one of this. I also had some wi fi problems after i linked it my router. It turns out that when my phone mobile data was turned on, i coudn't access the GBS. So i disabled my phone mobile data every time i want to manage the gbs over wi-fi.
Hi. Yeah these things are sensitive to electrical noise. Probably going to try to remedy this later on a video still don't know if my idea will work😂
I will try today!!!!
Hi. Can you tell me if the dc power supply is centre positive or centre negative? Thanks for indepth video.
Hi. Just checked . Center positive, 5V 2A. Hope this helps
Great video!!! What model power supply should I buy for it? I bought from Aliexpress and they did not send me any power supply. Thanks all
Hi, yeah some bundles come without it .
PSU is "5V 2A 2.1 x 5.5mm"
search for this exact frase in aliexpress and you should geta match. there are also USB-A to 5.5x2.1 adaptors and if your USB adaptor can supply 5v that should work as well.
the GBSC dose not come close to consuming 2A so you may be ok with a 1A supply
Good luck 🔌
hi i was wondering have you tried a dreamcast over vga because i cannot get it to work properly
Hi, I have not tried that yet but , i am working on making a review video where i test all my consoles in RGB/composite and component on the GBSC to see the results and ofc if i have issues white any of my consoles outputs 😁
Any luck ... I can't get mine to work either
@@ComsiCaterpillar afraid not just a rolling screen
@@mikedavidson1142 Have you found a different solution ? I'm eyeing the DCHMDI or OSSC
@@ComsiCaterpillar yes i have a ossc now and it works great
Hello friend, how did you manage to solve the WiFi problem?
I have the same situation and when I set it to 1080px720p the GBS CONTROL stops responding!
Can you help me please? Thanks...
Hi friend 😊 that's what I am here for. So in my case it's the frequency of my home router for my internet was set to channel 6 and o changed it to 11 and it fixed the problem . It's more a workaround than a fix .working on a real fix for this still a work in Progress
So short answer open your routers settings usually found on 192.168.0.1 there is a sticker on the router. And user name and pw. Search for WiFi settings and choose a difrent Channel and reboot the router . It should work now
How was the psu that it came with if you chose one of those options on Aliexpress?
The PSU that cam with the GBSC , works fine 2A 5V nothing special but it does the job.
actually didn't have any options when ordering just choose region (EU in my case )
due to this being a video (upscaler/ video decoder ) noisy PSU can affect it quite a lot
@RetroUpgrade Hey, thanks for the response, that's good to hear. Maybe the listing was different 4 months ago when this video was produced, but now on their page, they let you choose between US, EU, AUS, or no psu at all.
The yellow output isn't a composite port, but rather composite sync for RGB.
Yep 100% right I'll be making a follow-up using composite to RGB/VGA adapter and also have comparison with most of my consoles 15 different ones
@@RetroUpgrade Subscribed and looking forward to it!
Do you know if it works with a composite crt?
No unfortunately it only has VGA,component,RGB,and HDMI output. No composit support at all witch 😔
I tried to put my control on my wifi network, now the web UI won't work at all. you skipped past the part in your video, how did you get it to work again?
Yeah think i forgot to be specific. The issue is when you use HDMI and your WiFi channel have same frequency. . So the fix is quite easy just change the channel of your home wifi network. Mine dident work when on channel 6 but works fine on channel 11. Hope this helps
@Retro Upgrade have u tried upgrading the firmware on this
Yes at the time i recorded this video i did both with the official fw for the device and the gbs-control bother work but no real change in behavior. Will check if there are new updates and make a video
Update. The official fw is same as back the GitHub retroscaler/gbsc is on version 1.0, 2022 dec29
The gbs-control is aperantly being updated still. 2 Weeks ago last update on. Led screen and sync .
Only hard part with this firmware is its not pre complied and a pain to setup 😂🤣 I'll record a video I guess
So I bought a BitFunx GBS-C, here's my review:
When you can actually get it to show an image; it's great. Other times I'll be switching presets and resolutions back and forth over and over, until the mode that I know worked previously, actually works. Sometimes turning it off, and then back on, works. Basically, it's a buggy piece of shite, and I'm quite disappointed. Too good to be true. Used with PS2, Wii and Xbox Original via a component switch box, and a PS1 via SCART. Also, it really ought to come with a detailed instruction manual, which it doesn't.
100% agree here , its very unreliable, i am actually looking in to the code and the PCB designe files to see if i can find anything that could disturb the Sync separator circuit as that's the main problem (getting sync), could be that they forgot something that is required , or introduced noise from some other chip when designing them .
also the 3 variable caps to "set color" are usually removed when preforming the mod on a GBS8200
maybe related to those .
this will take me some time to wrap my head around the issue , but now that i have a oscilloscope i can dig deeper finally :P
thanks for sharing
Retro friends, I'm having a problem in one game in particular, Top Gear, when the second player enters the box the screen shakes and disturbs player one. Can anyone explain how to resolve this??? I thank!!!
Unfortunately i don't have top gear game. For what console? I can dig around and see what I can find
@@RetroUpgrade Super Nintendo, Top Gear. I already replaced the Scart C-Sync cables with RGB and the problem continued, replaced the 5V 1.5A source with 5V 2A and continued, even replaced the console source and continued. However, when I use another converter, HD Video Covert, it works perfectly.
@@RetroUpgrade I also put the same game on the console, Super Famicom, and the failure continued.
So it sounds like same issue some ps1 games have where they change the resolution dynamically and the scaler can't process it and gets confused. Resident evil does this . Between menu and game. I'll check around to see if a
Can figure out a fix . Gbsc firmware is open source so it can be modded to Handel it
@@RetroUpgrade Wow, I played Resident Evil 1 and 2 here on the PS1, it ran fine.
I plug my ps2 rgb and i hear sound but cant see anything
I got my PS2 cables will do somee testing. Can be the resolution the gbsc clone can't Handel anything over 480p on my testing
@@RetroUpgrade would really appreciate your help mate, tried all possible button combos and did not get image. It’s simply ps2 > rgb to gbs control > hdmi out
PS2 RGB is sync on green. You may need to toggle that setting.
Do you know if they fixed the problem with the composite cable not working ?
I don't think it is actually fixable , at least not with the PCB designe for the GBSC and the other versions .
but the main chip used is actually capable of taking a NTSC/PAL signal as seen on : www.tvia.com/en/show.aspx?mid=334&id=34 the chip name is : Tvia Trueview5725
this means it can actually be morded in to it , i have look in to it a bit but don't have the time for now to do any Reverse engineering to make a mod but it should be possible, if i get some spare time ill bring out my new scope and try to make it work . will probably need a addon board or something but i have PCBway as a sponsor so shouldn't be to hard to make one :D
Ill defiantly make a video if i start working on this as i think it would fix a few things this device needs , also trying to fix the HDMI/WIFI cutout bug in hardware i have a few ideas :)
Update: checked the datasheet, it needs external hardware to do the splitting up the singla part (Notch filter from splitting Y and C to YUV(YPbPr)) , but it has integrated deinterlacer and some other nice filters for composite video signals , will make a external board and solder it up and try to change the firmware where i can choose my new bord input and use all the filters .
@@RetroUpgrade Thanks for that, might show someone at work who is trained in electronics to see what he can do.
This version of GBSC in the video doesn't have composite input at all. Search for more expensive version with second PCB above the main PCB (transparent color of the case). It's has a composite electronic site on the board. But there a lot of complaints of it's shitty quality. So don't buy it and try to use separate converter for specific composite output with better quality.
@@Roman-Shipilov Thanks
I just bought it. And its a shame that it cant use AV. I use that VGA Adapter you showed but the Pictures dont look good :( please help how i can use AV at its best quality with the GBS Control. And please make more videos to it :)
I have ordered another (composite to VGA box ) ill try that one and keep you posted :), this one also has S-video , some consoles have S-video as well and would look better then composite :
es.aliexpress.com/item/4000092539254.html?spm=a2g0o.cart.0.0.1e7a7a9dfDxTFU&mp=1&gatewayAdapt=glo2esp
what console/device are you trying to use ?, maybe a way to mode for RGB or S-video atleast
Gbs-c vga + ossc = hdmi. Best solution for 480i to 240p games.
I use for ps1 : gbs-c + ossc + frammaister + mclassic = soft and clear picture.
That's a really nice setup you got there😊
How do you combine the Gbs-c with the ossc, and how does the combo affect deinterlacing?
@@betweenthecolors ossc digitizes the vga signal, I select the pass-through mode on ossc. There were no problems with the image. I finish polishing framemaster and mclassic, because I don't like stairs and I get 1080p. gbs control choose 720p.
@@actionfigurestoysandballoo3831 Very interesting, I will consider this. If you don’t mind me asking, why the Frammaister and not a Retrotink product?
@@betweenthecolors I haven't purchased retrotink yet. That's why I use this chain. although I'm not sure that I will get the desired result from retrotink 5x, because I do not like pixelated images and, in addition, with a lot of ladders. Of course, the minus of the chain is more input lag, but I use the Benq zowie monitor, specially released for ps4 and did not notice it myself. Of course retrotink 5x has masks that imitate old type monitors, but I'm not a fan of this solution. so I'm in no rush to buy it. By the way, 8 and 16 bits look great in a bunch of ossc RGB to hdmi + framemaister 480p (picture setting) + m classic = soft cartoon picture, ladders and pixels are moderately tidied up, it was framemaister that gave a soft picture without inflection. if you exclude it and immediately after ossc mclassic , it will be ugly, which means framemaister does a micro reduction of ladders and thus mclassic works as it should.
PS2 outputs RGsB if you set it to output RGB, and play games at 480p or higher.
How does it compare to retrotink 5x
Well I don't have a 5x so can't say for sure. But price this wins for sure. The quality seams to be the same. now for ease of use stay with the 5x the gbsc is fiddly to get working. But when it works it's really good
It doesn’t display, I tried my og Xbox everything is plugged and powered on but doesn’t work. Can you help?
What cables are you using on the Xbox. RGB or component ?
@@RetroUpgrade component
@KanyeWestLover12345 ok sounds like yo did not select correct sync. So choos sync on green , make sure compatibility mode is off.and also make sure you rgbs sync is off. Give it about a minut to sync first time. What output are you using? Hdmi?
@@RetroUpgrade HDMI, I’ll try that tomorrow and let you know how it goes.
@@RetroUpgrade still no signal.
Inwidh it did not need a phone. My phone never works with apps right
cómo conectar SNES sin RGB a control gbsc
No se puede sin RGB o un convertor composit a RGB. El gbsc solo acepta RGB, YPbPr y VGA. . El connector Amarillo solo se usa para Sync
does it work Playstation 1 via RGB ?
Yes it should work on any RGB , RGB-S and Y, PB, PR (component)signal , i am waiting for some parts to make a show case for all my consoles on the GBS-C.
ordered some Cables for RGB support and a Composite to RGB converter (for the consoles that only have RGB like the NES)
@@RetroUpgradeThank you
Great video. I’ve ordered the GBS-C and should have it soon. Can’t wait for your next video as I’m unsure what SCART cables to get for my SNES and PS1. I’m hearing that it won’t work properly if they have c sync or sync over luma on the SCART???
@@justindavid571what happened?
I’ve not tried the PSX yet, but the SNES over RGB scart works fine with it 👍
I take it the unit has it's own mac address ?
Yes it does. It's marked under the machine
@@RetroUpgrade Thanks for that.
