Yesterday I've been working on a smooth scrolling driver for Nemesis2.
It's starting to work pretty well now, and it looks pretty cool.
In nemesis games however, you will notice that for this to work perfectly, the rom needs to be patched:
Right now the background scrolls smoothly, but the background stars (as you would expect) not. Also the sprites which 'sit' on the background are still jerky (some enemies in stage 1 for example).
Someone cares to help with patching the nemesis2 rom for this? :-)
Besides all this, sometimes the background jerks a little as the pixel offsets and the 'real' back ground scroll gets out of sync sometimes (as far as I could see it, this happens sometimes in stage 3).
I'll fine tune the driver and expect a release this week.

This sounds great 
Nemesis 2 is my all-time favourite MSX-game and I most certainly will give it a try when you release it.
Too bad I don't have my old Arcade Turbo Joystick to play it with anymore

I just implemented the smooth scroll in knightmare too. In this game it works perfectly, and it just took about 10 minutes to implement! :-D

I guess in the Nemesis saga there's some RLCA which does the star pixel movement which you need to disable... done that now for nemesis 1, 2, 3, salamander (horizontal scrolling) and parodius.
still need to look into salamander vertical scrolling...
the enemy part is trickier than the stars thing though... |

Hi Erik,
First of all, congratulations for your great work with your emulator.
I'm a java programmer too, and I like your approach of improving msx games experience in your emulator. I would like to discuss some ideas with you, and maybe I can help you with some things. Please write me at: mauricio_motta (at)terra(dot)com(dot)brNOSPAM

Unsmoothened the stars in vertical scrolling as well now... From the link I previously mailed you, remove the -hor to download the archive with the correct version.

I guess we will later this week... as erikd already mentioned in his initial post.
btw, how's the sprite acting in knightmare when you 'lock' him behind a row of pilars, the water or something? does it scroll smoothly too or still make jumps of 8?

It still makes jumps of 8. As do the end of level bosses.
It'll require some rom patching, but it happens on so few occasions...

BTW, I'm also preparing a source code release.
