- Added the alt tilemap layout used by f1superb for the backgrounds


Date: Tue, 10 Nov 2009 14:47:56 +0000
From: David Haywood <neohaze@nildram.co.uk>
CC: Philip Bennett <p.j.bennett@gmail.com>
Subject: Re: MS32 update

It actually decodes as 2048 wide line data.

I don't know how to use it tho, I guess it's possible the buffers aren't 
valid for the same reason that the road is always straight (maths dsp / mcu)

f1superb - the road is always rendered as straight.
- the game has an extra roz layer and extra roms for it
- the game has a road layer and extra roms for it
- there is an unknown maths DSP for protection
