Since the OSSC Pro can do downscaling, I think so, but I haven't tried it with the PS4, let alone re-released games from M2. As for a rotated retro CRT, it may be up to each game's programming, but at least Battle Garegga seems like it should: viewtopic.php?p=1228860#p1228860:
縦画面レトロモニター(左回転): Vertical, retro monitor (left rotate)
This sounds like the remake's screen real estate placeholder stats are removed and you'd be rotating the monitor manually, but I could be wrong as I don't have the game to try.

The OSSC Pro doesn't support changing rotation itself yet, although it's a planned feature of course.

Yes, I have my ps5 connected via a hdmi selector switch. One to the tv and one to my Ossc pro. I play Ketsui on my tate bvm in crisp 240p.

You can rotate the game in menu and scale the image pixel perfect. Reach out if you want more info, I do the same on my Nintendo switch for Mushihimesama DDP and espgaluda

A question about the sync length parameter which is hidden in profiles on the OSSC Pro; does it do more than make sure that the active area cannot intrude on the sync period?

I've made a spreadsheet to decode, modify, and re-encode the HEX values for profiles and just set the horizontal sync length parameter to correspond to 4.7 µs or 2.35 µs as needed, but knowing how much that matters in practice can be useful. :)

Sync length is mainly relevant in output presets when used with analog output. For sampling presets it does not really matter except in A-LM when it selects a preset without a common group (currently PC modes 800x600 and higher) and copies its timings to output timings.

Any ideas when the Extra AV Out for OSSC Pro and AV input/output adapter will be available? Want to get this in my Astro City for PS4 Shot Trigger Games.

Thanks

I believe lead time for Extra AV Out cards is relatively short (max. 1 month) while AV I/O adapters need SCART connector which are not as easy to source nowadays (TME should have them restocked on week 21).

marqs is it possible to add HDMI-CEC support? Would be great to have OSSC turn on when TV does

Depends if I manage to find CEC programming manual for the HDMI transmitter chip somewhere. It's quite frustrating being forced to use chips from manufacturers that provide little or no information/manuals without NDA. That also applies to the RF tuner chip which took lots of time & some reverse engineering to get working. Got that done in the end unlike another unlucky engineer trying the same elsewhere, but I can't say it was time well spent (and the PCB is pending another redesign with metal RF shield which hopefully resolves remaining noise issues).

As one of the people championing your efforts to add the RF connector, I'm sorry it wasted so much of your time, but am glad to hear that you've succeeded where others couldn't. It's sad that such a common older technology never became freely understood with hobbyist documentation, or that older documented ICs have no modern compatible replacements still being made.

Anyway, I wish you all the best and hope something will have made it a worthwhile experience in the end.

Cool. Will keep an eye on this. Thanks for the consideration
