I have expand the ROM so hackers can add more new codes in the hardwired bank.

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

LDA bank_number
JSR $FFB0

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 $FFB0
JMP New Location

or

LDA bank_number
JSR $FFB0
RTS

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

Changes for this version 1.1:
Expand the ROM so hackers can use all the free space in the hardwired bank.
