INES Mapper 029

This mapper was allocated on 15-nov-2013 by a mysterious jerkface to implement some homebrew games, including Glider. FCEUX acquired support on r3029.

The board includes 4x banks worth of full 8KB CHR ram, and 8x 16KB PRG banks.

It is hard-wired for vertical mirroring, and contains 8KB of WRAM mounted in the usual place. There is no battery, but pads are present and suitable for such a purpose if anyone were so inclined.

The board contains some sketchy provisions for reprogramming the flash via the flash /WE being wired to EXPO
