A new FPGA core release: FSB140414

This time again only one fix: the mighty sprite collision detection.

Several problems in some games appear and Yaqube finally found a so far working solution.
There is an undocumented function in the real Denise chip, needed by Archon-1 and Spaceport game.
This function is now implemented and the named title + Rotor game (I read about it in WinUAE sources) are working fine.

If there still is any trouble, please let me know.

Fixed version: r2 with known good working DSKBYTR register handling.

Have fun with Minimig :)

Thanks for the report, I will take a look at this title ASAP.

Found the problem... it was my own fault in an forgotten attempt to make the DSKBYTR register more functional :o
A fixed core "release 2" is attached at 1st posting.

@boing4000: chaos, who's the mantainer and developer of the awesome DE1 port, has modified your latest sources, and has moved the keyboard emulation to the arrow keys + left ctrl + left alt, as I SO much love on the DE1 port.
He has compiled a working version, but he had some warnings upon building, so he also passed me the changed files, based on your latest sources (FSB140414_r2).
So, can you *please* accept these changes and produce a FSB140414_r3 with the "new" joystick emulation?

I'm attaching the modified files.
Thanks in advance! ^_^"

Thanks for the files and info.
I will have a look at it and when it fits my impression of usage, the changes will be used further on.

But I have to mention: CTRL as a joystick-fire key can be a problem because many KVM-Switches use it as a trigger to switch the inputs. I do have 2 of them and this key maping would be unuseable.
ALT key may be a better choice. But I have to check it out anyway :)
