Watching old "Let's Play" videos was a good idea. These effects used to appear and fade out slowly. Not sure why they aren't doing it anymore. Must be a feature of the MMF engine that has become outdated by Windows updates. If so, it's going to be fun finding a work around. ... It appears they both use the built in "Fade" transition effect. Objects which are manually programmed to fade seem to be working fine, e.g. water bubbles. I'll just have to make these fade manually too.
Edit: I've fixed it in KS+, will be in the next release. They look and work so much better, just like they used too. I'm putting the details here for any other modders who are interested.
The save effect is supposed to take 1.43 second to fade out. I approximated this with 7 frames, the final frame being all black, running at a speed of 24 centiseconds. So, we reach all black at 1.44 seconds. Note, the draw method is Add, so only the bright parts of the image are seen.
The spring effect is supposed to take 1.1 second to fade out. I imitate this with 6 frames, the final frame being all black, running at a speed of 22 centiseconds. So, we reach all black at 1.1 seconds. Note, the draw method is Add, so only the bright parts of the image are seen.
Below is a sprite sheet for the 2 animations. The individual frames would need to be separated to their own images to be imported into MMF.
