Only bottom left quarter of screen visible

[Songs]

Hi all,

This is my first post so if I don't put the right information in please bear with me while i learn. 

I have setup the bootleg as per the instructions here: http://forums.qhimm.com/index.php?topic=13212.msg183580#msg183580

Initially the game was working OK but a bit laggy.  I tried to change some of the settings in the configuration screen of the bootloader to make it smoother but all I ended up doing was making the game display 7 basic colours when the eidos screen comes up and I can only see the bottom left quarter of the image. 

I've tried ticking and unticking the various options but I can't seem to correct the problem. 

Only the bottom left quarter of the normal screen is visible. 

Immediately after I run the game a windows error message comes up for an instant "a running program isnt compatable with certain elements of windows". 

Am running windows 7 home 64 bit version with radeon 1.3GHz graphics card. 
Original FFVII 1998 PC box game installed. 

Thanks in advance.

A message also comes up saying the colour scheme has changed to windows 7 basic.  I'm not sure exactly what it says after that as it only flashes up for an instant. 

Aargh so frustrating!  Just want to play!
