Is weave deinterlacing possible on the base OSSC 1.8+ ?

[xepher573]

Firmware 1.11 fixed all my issues with sync on ps1 and ps2 (@480i). Thanks marqs!

Update: I managed to finish the mod and everything’s perfect! except one thing: PS2 @ 480i (through component). 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 (through component) but Sega genesis (through SCART) getting no sync (OSSC display was flickering with different frequencies and the tv had no signal). Then I tried firmware 1.10 from this github issue and everything worked (but PS2 @480i like I said).

Thanks @marqs for the hard effort! I plan on buying the OSSC pro once I get a job since I find it to be a better option for me than the retrotink5x and the GBS-C doesn’t fullfill all my needs (plus the retrotink4k is way above my price range).

I also have too many consoles to deal with and I don’t wanna use a component/scart switch.

Update: so I decided to turn it on anyways and it works fine without the R35 resistor but without the wire from it to pin 25. But after the update to firmware 1.09 it can’t get sync with any of my consoles.
So I reverted back to the old firmware. Anyways, I’ll get a better soldering iron and finish the job later.

I managed to desolder the R35 resistor without damaging the board and the pad however, I’m using world’s worst soldering iron and I can’t really melt my solder to get a wire from where the resistor was to pin 25…

 

If I turn on the OSSC without the R35 resistor but no wire to pin 25 will my board be damaged?

Interesting. Well, that explains it. Honestly, I think that it’s indeed a clone and in that case, I think doing the mod would probably result in issues anyways considering clones go for cheaper off-spec parts.

I’d much rather buy the original ossc but my country’s taxation policies on imports forced me to go for a chinese retailer (since this was the only way to dodge taxes back then and consequently, paying over 200% the product’s original price). I’m just glad you didn’t go for the scummy mega everdrive route where the original firmware bricks clone cartridges.

Now I’m left wondering if the OSSC’s available in my country’s amazon page are also clones or original models being resold for a higher price.
And in case I ever get my hands on a 1.8 board: would sync drops on resolution changes in PS1 games still be a thing on newer firmware? Is this issue only solved under the OSSC Pro?

Update: I actually had to revert back to firmware ‘latest_release_audio’ because every firmware I tried under “v1 series” (1.01 through 1.08) had issues with scaling not working, sync and image being duplicated on 480i sources.

So I’m guessing firmware versions 1.01 – 1.08 are meant for 1.8 boards? either that or I have a clone that only works with older firmware…

Ok, so I did install firmware 1.08 on my unmodded 1.7 ossc and it does boot and the shadow mask filters work. But sync is broken on all my tested consoles.
I tried setting the timings manually but even then, it’s bugged and not worth it. Line multiplication also doesn’t work.

The ossc controller also stopped working and I had to resync it with the ossc by booting it while pressing button 1 and then remapping all buttons.

I really wish I knew how to modify and re-build the 1.08 firmware to make a custom version for unmodded 1.7 boards just for the shadow mask, 6x and HDR features 🙁

So I decided to revert back to firmware 1.07.

[xepher573]

Would it be possible to backport some of the new 1.8 board’s firmware features (mainly the shadow mask/post-processing filters) to unmodded 1.7 boards? I’m not interested in some of the new features such as improved sync or 6X mode and I don’t feel confident on modding my board and sending it for a mod will result in excruciating taxes once the package is sent back to me due to my country’s jurisdiction (essentially, I’d end up paying twice the price I paid for my OSSC).
