OSSC Optimal Timing Profiles:



Provided on this page are single console "json" file links to each of the OSSC NTSC profiles research I have done for optimal timing (PAL and other formats not supported as I do not have the hardware to research them). I've decided to strictly focus on the timing and masking of these profiles, rather than worry about subjective preferences like color gain or scanlines. Each person's tastes are going to differ, so the important part is to get the timing correct.

In order to assemble these console-specific profiles, you need to load them one-by-one in the online profile editor in order to create a BIN file that you can imprint on an empty microSD card using "Win32DiskImager". Then you plug the microSD into your OSSC, go into the "Settings" menu, and use the "Import Settings" function. The OSSC online profile editor can be found here:

For those new to this process of importing console-specific profiles into the OSSC, I've made a quick tutorial video here:

I will be adding more and more profiles to it as I find time, and providing regular updates on Patreon and Twitter. For detailed information on all the features and functions of the OSSC, please visit this site below:

If you appreciate the effort that went into this research for both the OSSC and Framemeister, please consider pledging to my Patreon page: FirebrandX's Patreon Page

Every dollar goes right back into my research and development of these profiles and console modifications, so your patronage is greatly appreciated! All the best from FBX!
