Hi Guys, Currently i'm using 12V and 5V for power, VGA and Audio from JST but Jamma for controller. but I noticed that the board does not start if I connect the controllers before turning on. So i need to power the game until it boot up, and after connect controller. the problem might be that...

Noob question for great guys :-D I know you're all on vacation, but the brain never stops. About dancing eye keycus, more difficult one, since we need to reproduce code part that do hex to dec work, traslate to mips and path it over program. What about emulate it using cpld or a microcontroller ?

To me seems VGA + OSSC + Jassifier is the winner

Test1: GBSC scaler and jamma output View: https://youtu.be/pjltQ7tjsKQ Here OSSC + Jassifier and scanline: View: https://youtu.be/WoMExiek2uE Here OSSC VGA and Scanline: View: https://youtu.be/CZMn3YlABXc

Did a recap and its working, i didn't know that i can change contrast and gain on service :-D I put on 0 RGB gain, and its showing fine.

Here stickers if you need

It work but something seems really wrong to me on brightness. But no problem with GBSC its work better. (this is not a camera effect ! its really how it show)

do you think, can i connect VGA JST to my OSSC directly ? I got a bad image with Jassifier too much brightness, image with ghost. I didn't take a photo sorry Its work nice with jamma RGBS on GBSC

Thanks that what i think, if i use only 5v i need also jvs I/O But if i use 5v and 12v i can use RCA audio from JVS

yes but 3.3v pin2 seems not connected on System12 Can anyone with a JVS adapter try a System 12 board with and without a USB pad port? The question is, can a system 12 boot normal with a JVS power connector and jamma for input or need also USB jvs

Anyone know how work JVS connector ? Confirm power pinout ?

I think it's just about the internal clock. The real reason for removing it in my case was to wash the board and restore it.

Hello guys, Im trying to consoling my Tekken 3, as always i will use only 5v power since 12v is needed for sound AMP. But on Namco System 12 its will stuck on JVS screen test, loop test. Checking JVS power connector on board we have only this pins: 1 - 2 - 3 4 - 5 - 6 NC - NC - 5V GND - GND -...

i have the same problem, listen here: 1) are you using side jvs power connector or jamma ? Checking this power connector its have only 5v, so i think its waiting for USB JVS input If you try to power on using jamma, so connect the 12v rail... its will not waiting for USB since you are using...

Done some test, and this is the result for all need to replace battery on Namco System 12: 1) All characters unlocked is writed on your 28c16, its nonvolatile memory, so its do not lose a damn things. 2) The default battery is a CR2032, its not recharchable. So no mod is needed.

Hello Guys, I have to swap a battery on my new Tekken 3 pcb. I'd like to use a regular non-rechargeable battery, but I have a question. Since the default one is rechargeable, do I have to remove any components to deactivate the charging circuit ? Since my card has all the additional characters...

Hello Guys I got a CoolBoarders game on ZN1 board its a funny game but i wish if is possibile to convert it to TondemoCrisis :-D ( yes crazy japan game ) i love it. Same board but hey, half of components on. Coolboarders: Here TondemoCrisis board: Why is missing copletely audio part on...

Thanks at all guys, taken from Ivan, because shippin from italy.
