You can also use Nflate from http://www.romhacking.net/ Utilities to expand the ROM up to 512kb.

You can now use free RAM space at $5c00 to $5fff and $6000 to $7fff for cool or new stuff.

Bankswitching:
to bankswitch from $8000 - $Bfff and from $C000 - $ffff, here's how to do it:

LDA bank_number
JSR $FFE8
JMP New Location

or

LDA bank_number
JSR $FFE8
RTS

New location would be $8000 or $A000 etc... Bank 08 would be at $20010.

Hacks supported:
All!

Hacks not Supported:
Zanac/Zanac - FDS/NES + SRAM
MMC1 or MMC3 Hacks!

Use Delta Patcher to patch the xdelta file to the ROM. 
Ignore the checksum and then patch the file.

Changes for this version 1.0a
Expanded the ROM file size so Zanac Famicom Music Restoration hack can work.
