In fact, most NTSC CRT TVs were limited to at most ~216 lines due to the overscan, so the devs decision to limit the games resolution to 320x200 was probably not only related to Atari ST & PC portability, but also with NTSC compatibility.

This has exact the same problem, but in the opposite direction: Games designed for PAL320x256 will look vertically stretched when run on NTSC, and the screen will be cropped at the bottom, since the max number of lines will be 240p.

That same PAL aspect ratio issue affected even way more expensive machines like the Amiga.
It was somewhat expensive to deal with this in the 80s, so only devices produced in the late 90s/early 2000s began having proper NTSC/PAL aspect differentiation.

The MSX1 VDP outputs YPbPr, not Y/C. But it had some quirks that were poorly documented, and somewhat expensive to workaround. Most engineers had to cheat with some cheap trick.
If you really want good RGB, you’ll be better served by an MSX2/2+. Or install a TMS-RGB v2 kit.

Are those machines PAL instead of NTSC? That would explain the squished picture, due to the higher vertical resolution per frame (while keeping the same horizontal resolution)
The same issue also happens with the SMS and NES. Probably SNES too.

• Enhanced the coloring of some sprites
• Hardware sprite collision detection is now used when enough CPU time is available, providing pixel-perfect collisions.
• Speed optimizations: the game now runs much smoother and with fewer slowdowns even on non-turbo MSX2/2+ machines.

Nice idea!
But I wonder: isn’t it possible to solder tantalum SMD capacitors size 6032 on those pads?

They didn't install it by default because of a design flaw: it only works correctly up to SCREEN6.
On the screens that would desperately need it (SCREENs>=7), it doesn't work by default and need slow software workarounds to be minimally useful.

Yes, the Panasonic FS-AA51 power supply is identical to the Sony AC-HB3, so they are compatible.

I read over a past post here on replacing the Panasonic FSAA51 power supply. Some Sony's also used the funky 3 pin plug.
