Games that the MSX should have:

A pity indeed, the game looked pretty much finished.
Same for Wonderboy in Monsterland:

For me, to port some arcade games to MSX2 is a must plus some others:

• Terra Cresta, sc5 + SFG5/Moonsound/SCC (make your choice)
• Commando, sc5 + SFG5/Moonsound/SCC
• Slap Fight, sc5 + SFG5/Moonsound/SCC, moving side panel at botton to use hardware scroll.
• Rastan, sc4 + SFG5/Moonsound/SCC, scroll without masking borders (i don't really care) and sc5 for MSX2+ and Turbo R (like Compile did with Golvellius 2).
• GnG, sc4 without masking borders, I know ASM (and I got it of course ) and sc5 for MSX2+ and Turbo R.
• Green Beret, maybe sc5 this time, I think GB doesn't require a fast scroll.
• I'm not sure if is really doable, but Out Run/Lotus 2, with sc5 background and sc4 for the road, playing with sprites n chars for cars and stuff in a clever way, and without problems at borders because only will require 1 color so no color clash at all, running at 30fps?
• R-Type, sc4 with clever char rotation for a nice parallax scroll.
• Pinball Dreams/Fantasy/Illusions, sc5/sc7/sc8/sc10
• Sensible soccer, not sure if sc5 will be smooth and fast enough, if not sc4 should be ok with white lines for the field lines, and some kind of clever char [foreground/background] desings to solve the colour clash problem.

Yes a pinball game for msx or even with v9990 would be awesome. Personally I am very partial to Jack Crush from the SNES, but another good pinball would be awesome as well.

A game like nes remix for msx would also be awesome (all kinds of small parts/ levels of existing games where you need to accomplish a specific goal).

breakshot that was released on famicom and then done right with scc and such.

Tentochito port from pc98 to msx.

Bladelords 2 that never saw the light or barring that conversion of Towerfall ascension.

A new eggerland that incorporates the new bits introduced since eggerland 2 + editor.

Xanadu for msx 2 in a proper way and not a low grade direct conversion from pc88 without using the extra colours and other features.

King's valley 3 with additional features + 2 player mode so you can have puzzles where you need to solve them by joining forces (stand on eachother, do things simultaneously etc)

Convert GR3 or Lamulana because those games are so much like an msx game it is a shame it can't be played on msx.

+1 to Slap Fight, one of my favorites! The Arcade version of Slap fight does not have a side panel though (computer/console versions might have it, not sure).

That being said, I'm not a big fan of "ports", maybe sequels would be more interesting (as the port is not going to be as good as the original anyway )

+1000. Superb list!
