I'll check with Wolfgang but I think he is happy for me to post the core. It's really a test that the libraries etc can be used by 3rd party devs. You will need to flash to the new boot loader and menu system. This means the old amiga core will no longer work, and you will pester me every day for the new one - which is fine with me 
I'll post details asap.

LOL. Thanks Mike, I'd love to get my hands on Pheonix.
I might need to buy a second FPGA Arcade then.

I take it that reflashing to the new boot loader is done via a file on the SD Card?
One of the great selling points to me of the FPGA Arcade will be (with the new bootloader and new core) the ability to select at boot time which core (Amiga, arcade game, other system) you wish to run. This is a nice feature on the Chameleon64 which I currently have configures to boot into a C64, ECS Amiga or ZX Spectrum.
