A new FPGA core release: FSB150520

Feature and fixes are:
- sprite collision fix developed by "yaqube" implemented (Archon, Spaceport, Rotor, Starball games and Arcadia Megademo)
- CIA timer fix developed by "chaos" implemented (Batman The Movie & Flimbos Quest)
- more original memory mapping at OCS & ECS with only 512kb of chipmem setting (TGS Megademo & a Paradox cracktro)
- sprite enable/disable signal fix (Coppermaster demo & More Lemmings game)
- scanline effect of OSD background disabled at 31khz mode (better readability)

By now all tested title work fine. If there still is any trouble, just let me know.
Sources are included.

Have fun with Minimig :)

@Boing4000: thanks for keeping the V1.1 board alive!! :D
@chaos: can you please change the joystick emulation layout to your usual arrows + left CTRL, please? I'm sure it will only take a minute or two on your side....

Does this core need any special PIC / ARM core ?

At least release 100818 for PIC or ARM.
Best would be ASB140501.

Great ! I have the new ARM fw it seems ! And probably the other on the PIC Mig.

Does all MiniMigs support 49 Mhz ?

Actually yes. I only made the 42MHz core due to a few sensitive 68SEC000 cpu used on self made boards.
When your Minimig show the kickstart screen at Turbo mode, the 49MHz core works fine.
