Problemas com sistema MVS .

[Leonardofonseca21]

Não compatível com sistema neogeo MVS consolizad , na versão 1.2.1 era compatível hoje não consigo mais utilizar mesmo estando na ultima firmiware, roda travando
problema de imagem , testei em 2 sistemas MVS e ambos apresentam o mesmo problema na imagem ,além disso não aparece mais a opção para adicionar scanlines , menu fica oscilando piscando e a falta de sincronia que vem desde o seu lançamento.

O som ta normal , mas a imagem na MVS falta quadros de animação , como se pulasse eles , testei com 2 MVS diferentes e jogos diversos originais e jogos da 151 in 1 .

Você já tentou ativar ou desativar o modo de compatibilidade nas opções?

Às vezes, ele pode causar problemas com alguns consoles, tanto ativado quanto desativado.

Você encontra essa opção nas configurações do sistema e, de acordo com o manual, ela é destinada ao Neo Geo e ao Sega 32X.

Na versão anterior do firmware RetroScaler, essa opção vinha ativada por padrão, mas nesta versão, a função está desativada.

Como você tem um Neo Geo, suspeito que a função esteja desativada.

Can you give us some more information? Input signal type? Resolution? Cable used?

I don't have an MVS to test with, so I need as much information as possible to understand if there is a problem and where it lies.

Olá, boa tarde .

Segue lista ....

MVS consolized , cabo scart C-Sync ,imput RGBS /output 1080p na GBS control pro , permanece o áudio aceitável porém não roda 60hz .

Já testei com o Bob e o adaptativo, ambos só servem pra adicionar scanlines , mas está sem condições de uso .

No super Nintendo o audio precisa de correção ele ta estourando, nessa ultima atualização aumentou o volume porém a qualidade está baixa.

Problema crônica de sincronia desde o lançamento do equipamento... nos sistemas neogeo quando tem uma tela branca ela embaralha toda .

[Leonardofonseca21]

permanece o bug do controle remoto , após alguns minutos de uso vamos usar e embaralha tudo na parte superior da tela .

Na firmiware 1.2.3 funciona o mvs sem bug rodando abaixo de 60hz , na nova somente o audio está ok, a imagem continua ruim e sem condiçoes de jogar .

Hello, I apologize, but I am having difficulty understanding what you have written. Could you please write more clearly and in English?

I noticed that you mentioned several versions of the old RetroScaler firmware, both 1.2.1 and 1.2.3, and it seems that you are experiencing a problem with the MVS.

Could you describe exactly what is happening, what configurations you are using, and which firmware versions?
Without the hardware, it is very difficult for me to identify the problem. I need more details to find a solution :)

In general, I understand that it worked up to a certain firmware version and then stopped. Could you tell me, perhaps by testing to be sure, up to which exact version it worked?

[Leonardofonseca21]

the current MVS system is not working at 60hz, the audio is perfect but the image is slow, stuck, in previous versions it worked in version 1.2.1 1.3.1 with the chronic synchronization problem since launch. My current setup looks like this: 1 shielded scart c Sync cable mvs consolidated adequate power source, everything is ok on the TV, the problem is the GBS control pro. Bug defect in the remote control: after a few minutes of playing, when we use it to change a profile, lower the volume or make any changes, the screen becomes buggy. audio problems: the audio on the SNES is blown

Does the OSD menu appear randomly even though it should be “off” after a few minutes of use? I ask because other users have had the same problem, and it appears that it was indeed a faulty gbsc-pro; likely, a defective batch was produced.

Would you be able to make a short video of the issues you are experiencing?

Posso sim , te envio por aqui Em dom., 11 de jan. de 2026, 06:25, Manuel Valentino < ***@***.***> escreveu:

O menu OSD aparece aleatoriamente mesmo quando deveria estar "desligado" após alguns minutos de uso? Pergunto isso porque outros usuários tiveram o mesmo problema e parece que realmente se tratava de um GBSC-Pro com defeito; provavelmente, um lote defeituoso foi produzido.

Você poderia gravar um vídeo curto explicando os problemas que está enfrentando?

Good evening, I had opened a post about scanlines on the Neo Geo CD, and you mentioned that it works with BOB mode. Yes, it really does work, but since I'm doing sync striper installations for clients with synchronization problems, I noticed on a client's GBS with an older Retroscaler firmware that scanlines works normally on the Neo Geo CD even in adaptive mode. I really think there's still something wrong in that regard. I also have a problem here that I don't know if it's my GBS, but some functions, for example, activating or deactivating adaptive mode, cause the image to disappear and not return to the selected option. I lose signal and it only works again by turning it off and on. Some of these functions that make the screen flash and then return are a struggle to get working on mine. Is it possible to modify the software to track whether there's a signal on the TV or not and automatically make new attempts? Thank you in advance for your brilliant work!

Acabei de testar a firmiware e com MVS permanece o defeito ... quando ligamos e estamos RgBS , e a resolução full HD, mesmo com Bob ativado ele roda 30 frames ...infelizmente pra MVS não ta funcional... já testei com 2 scarts diferentes um com LM e outro sem porém não resolve o problema . Quando ligamos a MVS e vamos utilizar o menu ele fica bugado piscando o menu ... O problema se repete ... testa a versão 1.2.4 ela roda liso no MVS porém não tem sincronia . Parabéns pelo trabalho Em seg., 26 de jan. de 2026, 22:33, HunterGamess85 ***@***.***> escreveu:

I have this issue on my NEO-AES3-5. It's a revision that has composite sync wired to pins 3 and 7, just waiting for a resistor so I can restore proper csync. I'm using a Retro Gaming Cables csync SCART lead.

The image seems to freeze and jump slightly every few seconds. When it does this it will update the image. Enabling scanlines doesn't show any scanlines. Turning the sync stripper on or off makes no difference.

Enabling dev mode and turning off the sync watcher gives a rock solid image with no stutter but the scanlines still don't work. It's ok as a workaround but sync watcher has to be turned off every time as it doesn't save to the profile.

It's unplayable with the sync watcher on, but with it off it's perfect. Had a nice session of Ryuuko no Ken with no issues apart from the lack of scanlines.

[segasonic44]

Restoring csync, correcting the RGB levels and removing the AC coupling hasn't made any difference.

It appears to be a known issue that never got fixed, but building firmware from a certain older commit will make it work.
