Wow, When we first decided that we should improve the Lolo 2 run, I had no idea it would be this much. Amazing... Here's some comments on your improvements:
On 5-2, I managed to pass the water the last time a little smoother, saving an additional 5 frames. So the time on 5-2 has been cut down by 905 frames now.
Leve 6-2 could only be improved by 54 frames, you can't push the egg in the water to the farthest left, if you do, it will have sunk before you get back to it after picking up the top heart.
I'll look into 7-2 some more soon, I'll get back to you on that.
7-5 could only be improved by 2 frames. This is because whenever you get off the egg, the egg stops moving for a few frames. So by taking the egg on the way down as you said, the egg stops floating for a few frames. By taking the egg the way I take it in my current run, I don't have to put up with this waiting, since I take the egg when it's already stopped at the end of the river. So this saved mereley 2 frames.
8-3 was improved by 102 frames thanks to your tips. It was some trouble dodging all the Gol fire though.
And I don't really see how you mean on 8-4... Could you post and .fcm that shows what you mean?
Your improvement on C-1 did not save ~20 seconds, but it did save 258 frames, which is 4,3 seconds.
Here's how I played all these levels:

As always, all comments are welcome. I haven't the time to test the rest of your foundings, and I'll be away for this weekend. But I'll get back to this on Monday. As usual, thanks a lot for your tips hanzou, you have helped out a lot with this, and it's very appreciated. I hope you find some new stuff while I'm gone during the weekend! :)
Oh and hanzou, did you see the savestates that I posted? If you use them you don't have to fastforward to reach a certain level, just load the savestate for the level you want to see. To load them, open the Lolo 2 ROM, play the the movie you want to see, press File, Load State From, and then choose the savestate for that level. But on the other hand, if you find improvements by fastforwarding through the movie, then maybe I should let you continue with that. :)
EDIT: Managed to save additional 70 frames on C-2 now:
