We would like to start by apologizing to everyone who has received a Super SD System 3 with lower quality RGB video output than expected.
During the development of Super SD System 3, we tested numerous games on our TV setups without noticing any noise in the RGB image.
Castlevania was one of the games we used for our tests.
Here is a video taken with a stock Coregrafx 1 console and IFU CD setup over its composite video output. It has been captured with a Framemeister upscaler and Elgato Game Capture HD60 Pro:
This is another video of the same game, captured with the same Coregrafx 1 console, but over RGB with the first version of the Super SD System 3:
It’s clear that the RGB image on the shipped Super SD System 3 is a large improvement over the stock composite video.
Even though Super SD System 3 was actually designed more as an optical disc emulator than a RGB device itself, offering a quality RGB output on the device has always been one of our goals with this product.
As soon as the tests and comments from the first received units came in, we halted shipments to analyze the reported RGB issues.
The results of our tests are the following ones :
In Castlevania, using the Framemeister and our tested CRTs and LCDs, its hard to notice the issue but it can be seen at minute 4:01 if pointed there.
There is some noise in the background there that can be seen while the background is moving.
This issue is hard or even impossible to notice on most TV setups cause the different upscalers used by current TV manufacturers filter the image in different ways, hiding this noise more or less.
On upscalers like the Framemeister and OSSC its easier to notice because of the way they do the upscaling (filtering less of the image).
And on most CRTs it’s difficult to notice as well.
With the help and feedback from the community, we have isolated the issues and they have been corrected on a new PCB design we submitted to production today, 24th January 2018.
These issues include:
1. Out of spec Composite Sync signal: This has been fixed on the new PCB by using the PCE CSYNC output to drive the CSYNC circuit. Now standard Mega drive/Genesis CSYNC cables can be used.
2. Audio noise: We have rebalanced the PCE audio that gets mixed with the CD audio therefore lowering background noise. The PCE audio was actually louder than on NEC's hardware, but by lowering it, it is now matched to the IFU audio output.
3. Video noise: This was the hardest one for us to notice during testing and the most important one to correct. This was fixed due to the fact the video amp referenced digital ground rather than analog ground. So now both audio and video grounds have been changed to analog ground. This has greatly improved video quality and removed any noise in the picture.
The new submitted PCB RGB output can be seen in this third video:
This last video of the same game was captured with the same Coregrafx 1 console but with the revised Super SD System 3 PCB.
The noise has totally disappeared on the same scenes where it was seen with the first PCB design (minute 3:57).
This noise issue is heavily dependent on the game being played and on the actual TV setup.
While on most games it’s impossible to notice, however in others like Bonk III it’s easier to see the noise due to the large solid color backgrounds.
Again thanks to the community we have been pointed there.
Bonk III stock coregrafx 1 composite output :
Bonk III first Super SD System 3 shipped pcb
Bonk III new pcb :
Because we stand by the products that we design and sell, we will be replacing the PCB of every Super SD System 3 that has thus far been shipped out to anyone needing this replacement.
We simply ask that you remove the PCB from the Super SD System 3 and pay to ship it back to us and we will pay to ship the new PCB to you. Returns will be handled by a new dedicated Terraonion support forum that will be setup within the next 6 weeks.
This is also how long it will take for us to have the new PCBs made and have them factory soldered. At this point shipments for existing orders will continue with the new revised PCBs.
All orders will be handled in the order that they are received. This includes new orders. Day one orders are first in line. Orders placed today will be at the back of the queue. We hope to be caught up with all orders and have units on hand for shipment within 24 hours later this year.
Although it has come at great cost to us in both money and time, we realize that redesigning the Super SD System 3 was the right call to make as our goal is to deliver the best quality possible in all of our products.
We hope that you enjoy using it for years to come.
