Thanks for the heads up! I don't actually own a PAL console but it is good information to have.

Thanks! Yeah I still have a ways to go on it and things to test.

Also, his board doesn't have holes for the unusual single DRAM chip Nintendo used in the later revisions of the FDS RAM Adapter which replaced the standard four DRAM chips.
Bakuten's adapter was designed to work with portable Famicom systems, or any other famicom that has a deeper spot for the cartridge. He talks about it here.
