I've previously blogged about Chinese SCART adaptors. These are very low cost adaptors which convert RGB SCART to HDMI, with two main variations based on their board labels: SCART+HD2 HDMI 2014/12/23 and SHD1000 V1.
In the comments, readers identified that the main IC driving these is the MST6M182 (specifically mst6m182xst-z1). After much searching online and a hint from reader mmuman I managed to track down the datasheet or at least one close enough.
Of note to retro-gaming and retro-computing enthusiasts will be the registers for de-interlacing, including options to disable it entirely (USR_INTLAC). I'm keen to hook-up a micro and start fiddling with registers, as I suspect these could be a very good low-cost option if adequate control of the images was possible
In addition, I've created a source repository to collect these datasheets. It's available at https://github.com/ObsoleteMadness/MSTAR_Datasheets. If you have any further datasheets, please submit a pull request, as I'd be happy to put them up on that repo.
