Skate or Die Mapper Conversion
From UNROM to MMC5 (from UNROM to Mapper 5)
by Dracula X

RELEASE DATE: 5-21-2020

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 $FFD7
JMP New Location

or

LDA bank_number
JSR $FFD7
RTS

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

This patch also works for:
Skate or Die (Europe)

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