Pimp my Master System! (Improved RGB SCART and FM Sound!) 

I think the best way would be to cut every trace to the DIN output, then wire them directly from corresponding pins on the CXA1145. You can grab RGB/ c sync and audio off it. My master system 2’s are extremely clean this way.

Thanks mate. And yeah, 100% agree on the mighty Master System.

Yeah, I simply wanted to try it and in some games its worth it, but in others - not so much

Make sure you see Pt2 where I improve on the RGB mod.

Eric Eric Yes pin 1 on the Connector is allready C-Sync.

@@xantam23 Oh - is it? oh well.

I did look at the pinout and it just said "sync" but could never find out 'what' sync. I guess that answers it.

Ok - rewired the cable to pull csync from pin-1 - nada

@@MrLurchsThings Yeah. It should be TTL-level CSYNC output.

Or just remove connector leave rf on 😅

Ive been thinking about this. I'm guessing either a) the OSSC filters better than my cheap upscaler (probably), b) the scaler and the OSSC simply handle the signal differently. Out of curiosity, do you have a screen with native scart?

@@MrLurchsThings I don't have any screen that natively takes scart, sorry. I suspect mutual friend Jeremy may do.

Same boat here, had megadrives and used a shinybow scart to component converter back in 2015/2016 and it was crystal clean, then a couple years after it was “all the rage” to be doing bypasses cos of jail bars I’d actually never experienced - until running another model one megadrive thru a CRT and seeing model one master systems do the same (like here) plus alll the stuff on the internet about people complaining about them over the years and various pins and traces to cut to help improve this ! I actually ended up making my own bypass board too just for something to muck around with cos covid killed my workload and I had too much spare time !

Sadly no. Its currently waiting for BennVenn to finish his LCD mod

No - it has to be a SCART cable to properly supports RGB and not just piping the standard composite single thru.

Usually a television has 2 scart channels. One for RGB using composite as sync and another where it’s just composite. The 5v is suppose to make it switch to RGB Channel or something so it doesn’t use composite

I actually had a PC with a PSG-based soundchip in it, the Tandy 1000. It had PSG 3-channel, a DSP for samples, and also utilized the PC speaker for an extra channel. So while games looked better on my next door neighbor's PC(He had a VGA with Pc Speaker only), they usually sounded much better on mine.

I think i did? I know I have with my SMS2

Mr Lurch's Things do you prefer 50hz over 60 for SMS?

50. 60 just feels strange and weird to me.

Mr Lurch's Things is that just for SMS, c64, Amiga? what about mega drive and newer consoles?

@@MrLazenby007 I didn’t grow up with the C64, so hard to say. They certainly don’t mess with my head like on the SMS and MD.

I honestly couldn't tell you. Sorry. Ive never used the bypass board.

@@MrLurchsThings no worries :) love the video and will come in handy for the FM Mod. Pretty excited about that. I really appreciate the feedback!

Depends where in the world you are. In Australia it has prominently been pronounced See-ga.

@@MrLurchsThings On the sonic screen when the sega logo comes up what does it say ? Sayga

@@RBKing80 With the FM sound - sure. But in Aus the first big success for Sega was the SMS2 which didnt have FM sound. 99% of our marketing was written, so it became See-ga for a year before the MD arrived.

I've lived in Japan and you are saying wrong. It's not sayga. It's seh gah even the sonic intro It's saying seeh gah. Lived there long enough too know you are also wrong.
