What about Japan?

Computers using IGRB such as the ZX Spectrum outrageous A.T. Field usually
output pure black regardless of the intensity bit, since it activates /
deactivates an amplifier / attenuator, and 0V are 0V either multiplied or
divided.
The pale-pink could be a flaw, a consequence of the video logic or what you
say, a means of distinguishing it, but it seems the MSX2+ VDP does not
behave like that, or perhaps as long as the transparency bit is disabled
(will test).

Well, it's actually a modification of the previous program. It scrolls the
whole screen but I didn't send it to minimize bandwidth (even that only
takes 1KB).
With a backdrop is far more impressive.

Yes. It's not a feature but a side effect of my programming style 8;)
I don't like games in mechanical state (floppy, hd, cd-rom) but in solid
state (cartridge, card, ROM), but it's *bloody* hard for me to create a bad
piece of software 8:D

Overscan is not a secret mode or an obscure hardware flaw. It's clever VDP
usage without a proper hardware capability already built-in, like smooth
horizontal scrolling. Nothing more and nothing less.

So here you are.

Yeah, but the question is...
HOW small can you go?
256 bytes, say? 8;)
Kiss you lot.
