From UNROM to MMC5 (from UNROM to Mapper 5)

RELEASE DATE: September 26, 2016

In order to get this to work, patch it to an unmodified ROM first and then patch one of the hacks to the file.
You can now apply any TGL hack to this hack including "The Guardian Legend WORLDS" Utility.

Bankswitch:
To use it, all you have to do is select a bank and jump to it.

LDA bank_number
JSR $FFC0

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 $FFC0
JMP New Location

or

LDA bank_number
JSR $FFC0
RTS

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

Have fun!
