I got many Mail with inputs how to solve my problems - thank you very much for support!
So the first thing I'm gonna do is to build some level-converters as on this page:
http://www.rocketnumbernine.com/2009/04/10/5v-33v-bidirectional-level-converter/
First I will try to get the SID-Socket running with a real SID and BiDir (the current solution is "write only" to the SID).

The Creative Break.....
.... didn't yield any fruits.
I'm stuck at several ends at the moment, mostly hardware-related as
- How to interface a larger number of 5V BiDir-Port to a 3.3V FPGA (Cartridge Ports and such)
- How to build some kind of SDCard-to-SPI-Interface which would enable upgrading the FPGA-Core, simpler than using a byteblaster.
As soon as I have figured out all hardware issues, I could advance to next next step(s)
On the HDL-Side, I can say that the solution fairly usable yet :) CPU/VIC/CIA are doing mostly fine, for the SID we have the SwinSid...
If anyone of you out there have any knowledge to share and would like to participate with this project, please contact me at d@c64.ch!

SpriteEnableX fixed
Thinking about Emulamer, I just had to fix the "SpriteEnable"-Stuff (Sprites can have DMA turned on, but still they can be inactive). Vice 2.3 (normal Version) fails at some of those tests, we (and Vice SC) pass all now :)
(Sidenote: Ruined Art still not working...)

Flatline by Emulamer works
Just stumbled across this today: Flatline by Emulamer - well, seems FPGA64 is finally "a halfway decent emulator". No fixing was required, it just worked...
FYI: Ruined Art/Emulamer does not work (yet).... my Sprite-Handling is still too buggy at some places.

$D013-Stable-Interrupts added..
After wondering why some parts of Crest Light bugged, I had to learn that there is another way to create stable rasters using CIA1 and LP (in short: you can trigger an update of $d013 (LightPen X) and $d014 (LightPen Y) by changing bit 4 of Port B of CIA1, as this Pin is connected to the LP-In of the VIC). Before, four parts of Crest Light where buggy, now the whole demo runs perfect.

Krestage 3 / Crest working
The 9th sprite was always there, now finally the VIC-Emulation also displays the 50 pixel wide sprites and the correct colors/data between the multicolor- and the FLI-Picture.

Edge of Disgrace / Booze Design with the latest VIC-Revision
Almost all bugs sorted out! Needed quite some VIC-Fiddeling for some stuff to display properly, but now it's as good as it get's. For the remaining glitches I have no idea where they come from :)
