Yes, the fast forwarding is unfortunately a side effect of a temporary 'fix' for the smooth-scroll effect.
I've up-clocked the Z80 a bit to prevent slow-downs because they totally break the smooth-scrolling, but indeed that sometimes causes speed-ups.
What I probably need to do is to somehow detect when the game-code is going 'over budget' and only then let the Z80 execute some extra cycles to make up for that, which hopefully makes the gameplay speed the most consistent.

I'll look up the exact addresses etc when I get home.

For Nemesis 3, I look at 0xe362 to get a pixel offset and I delay the actual pixel scrolling by one frame.

Maybe another option would be to detect when a row is actually being scrolled and sync the pixel-scroll to that (as address 0xe362 isn't always perfectly sync'ed with the actual character-based scrolling), but I think there's still some merit in the idea to dynamically adjust the Z80 speed to get the game-speed constant.

I test your emulator, very good job I lile a lot the experience of enhanced Nemesis 3 with Stereo sound and better drums.

Please fix that small bugs and release again, I want to play again

Is it possible for you to add a Konami game soundtracks SCC DSK to the emulator? I would like to hear all the music with the stereo effect and the improved drums.

I really enjoy playing Nemesis 3 with smooth scroll and the enhanced music. Good job!
I hope you can fix some bugs and bring up the emulation to MSX2 games.
Thank you.

I could just black-out that column, but I suppose it might be slightly harder to play if you don't see the sprites there too.

Thanks!
The emulator also supports MSX2 but unfortunately not everything works 100% (all Konami MSX2 games do work fine though, but there are a few disk games that don't work).

I'd like to hear all those Konami tracks too
So I'm working on getting things to work nicely with that Konami SCC DSK that can play everything.

It's not all that easy though; I have to be very careful with the drum triggering for each game individually (and sometimes even per song), otherwise it'll sound all wrong, and that disk image has so many games.
And the drum trigger set-ups for the real games behave a bit differently in this demo disk, so I have to sort of start from scratch for each game to get everything sound nice.

Can I switch between 50/60Hz? The music makes me sleepy on 50Hz
