A mini poll:
Which features do you think the old TMS VDP lacks that if implemented would have greatly improved game quality (MAX 2 features)
Valid responses are for example: (HW scrolling, palette, fast vram, sprites)
In others words: Which is the main 2 major limits in TMS VDP that are a big problem in game quality?

speed, and sprites (more sprites per line and/or bitmap sprites)

Sprites and Palette. I wouldn't even mind a fixed palette again, but then one which has more dark shades and a few replacements:
pub.unreal64.net/boor/msx1alternative.png
Sprites-on-a-row should be vastly increased. I could say bitmap sprites or otherwise MSX2 sprites, but they'll have to be somewhere in VRAM which is 16KB atm. Perhaps I'd find it interesting to have an alternative tilemode in which each rect of 4x2 pixels has 2 colors and where each character has thus 8 such rects. Same amount of VRAM, but horizontally somewhat more options at the cost of vertical options.

The MSX1 VDP is late 70s technology, most features we'd want would be too costly.
But sure, I can dream:
sprites: more sprites per scanline, per-sprite hardware x/y flipping, 3 colours+transparent, sprite size of multiples of 8 up to 64*64, per-sprite option to have its priority under bg tiles
palette: see above + I want pink too Running Naked in a Field of Flowers, but I'd rather have palette RAM

Scrolling would be nice too, but not really possible with 16KB VRAM and Screen 2, and kinda useless without hblank interrupts (eg. statusbars)

It may be worth studying the C64 palette, seen by quite a few as the best fixed palette among the 8-bitters.

First of all palette and second maybe....mmmm...hardware scroll registers.

I second that. The crappy c64 palette is the reason why all games look so bland. Throw in some NTSC signal and you're nearly on black and white.

1) Sprite mirroring.
Just a flag in the SAT to flip the sprite. This saves needed VRAM...

2) 3 colors per 8 pixels on a line Pattern mode.

These 2 must have been possible back in the days
