@marqs Can you add the ability to have saving and loading profiles includes the input and Colorspace/Sync type. So when you save a profle for say input AV2 YPBPR. and then use the OSSC and maybe switch to Scart RGBs and then you wanted recall that profile that was saved with AV2 at YPbPr it would switch to the input and recall the color…Read more

Thanks for the latest v0.81 update – stability fixes are much appreciated!

I’d love to see an optional **line blending mode for low-latency downscaling** (as alternative to decimation/dropping lines) in Line Multiplier / Adaptive modes. This would blend input lines (e.g., average 3 lines for 720p→240p) to reduce shimmering/artifacts on…Read more

It’s a Samsung from 2017 so quite old now.

Either way I don’t mind fiddling with the timings 🙂

Funnily enough this screen tearing has only started…Read more

@marqs YOU are amazing!! thank you for designing this amazing pieces of tech! I’m going to order a 2nd unit so I have one in living room and one bedroom!…

MarcoRetro should make a follow up on this!

@marqs Hi guys, if possible, please clear my doubts, does the shadow mask already emulate all the behavior of a crt including the scanlines? or even activating the shadow mask, do I also need to activate the scanlines to have an image closer to a real crt?

It only models shadow/slot masks as per name. You can simultaneously use scanline options to…Read more

According to @marqs :

To program flash, a combined FPGA image must be first generated and converted into JTAG indirect Configuration file (.jic). Open conversion tool (“File->Convert Programming Files”) in Quartus, click “Open Conversion Setup Data”, select “ossc_pro.cof” and press Generate. Then open Programmer and ensure that…

@JAMIEvx @BoldFusion When have you bought the board and do you remember which fw version was installed when you initiated the update? Did you start the update from test pattern or an active input? We may need to get one of these failing boards for return analysis and try to replicate the failure.

@marqs I believe it originally had 0.75 on it when…Read more

The label under the OSSC itself says “model 1.7” and I have been using firmware 0.9

I did the hardware mod so I could try the V1.xx series firmware a while ago and that disables the red light, right? Anyway, the remaining green light stays solid…Read more

for helping out!

so a H. Samplerate wit standard VGA 640×480@60 does the trick

can this be auto detected, and maybe programmed into next firmware?

sorry, but I’m curious about cause of your great work, this little 2K Scaler Device is getting better and better

maybe 480i 3x modes? ok I shut up 🙂  🙂  🙂

@marqs: Would it be possible to add an option called “No Audio Fix” that automatically changes Quad Stereo from “off” to “on” to “off” (or vice versa if it’s set to “on”) every time the OSSC Pro is powered on and/or an input is changed? It might be a quick, clean solution.

I’ll take a closer look at the cable. It’s a normal Mega Drive 2 RGB cable. Maybe the 75 Ohm resistor can be soldered into the scart plug.

in the schematics of V1.6, are the pins 126 and 127 connected to ground on the PCB ?

the images of the amazing soldering job by @morpheus_79 doesn’t show the pin 126 lifted, and why he (re)connected the pin 127 to ground?

if I want to convert my v1.6 to V1.8 is neccesary  lift the pin 126 and connect that lifted…Read more

Update: I managed to finish the mod and everything’s perfect! except one thing: PS2 @ 480i. Passthrough, line2x/etc…, nothing works. Tried both with default settings and Wobbling pixel’s PS2 config and timings. The OSSC just loses signal constantly and randomly.

I started with firmware 1.09 which resulted in PSP working but Sega genesis…Read more

Hey there. First post on this forum. Anyways, I just completed the mod and updated to FW 1.0.7. I came from 0.88a. First thing I’ve noticed is that the Allow upsample2x option causes a black screen whereas on the previous version it did not.

Any idea on the issue here?

Thanks

Is this new firmware able to support VGA (720×400, etc) to 1440p @ 70 Hz using pixel repetition?

@marqs, would it be possible to allow the reverse LPF to take negative values and thereby function as a forward LPF? This would be helpful for blurring dithering patterns in Genesis/Mega Drive games. The RetroTINK-5X allows this with its equivalent…
