Thanks Dee2er, ive uploaded the horizontal and vertical images with the brightness/gamma fixes/shader options, the PI has been overclocked in the config file in the root directory (revert to original settings if you wish) link below its an img file (best to open the link in Chrome rather than IE) :
HORIZONTAL

VERTICAL
https://mega.nz/#!yNVzGDpT!jtLiS1K8faHEafEdJVZrZqMPZ4bjiGxhns3_AsHDJZI
Adjust each emulator as follows in the linux partition :
MAME4all
home/pi/mame4all edit mame.cfg file gamma (current default setting) 1.25
MAME 106
home/pi/.advance advmame.rc display_brightness (current default setting) 1.25
FBA & MAME 078
Enter Retroarch menu by pressing player 1 start and F1 select quick menu then shader options then menu shader parameters and adjust brightness boost and gamma to required setting then go back a menu and select apply shader changes and then press F1 and player 1 start to go back to the game.
Also I found this site : http://thepinnyparlour.com/download.html theres a very handy script to separate horizontal and vertical roms (VMOVE.BAT and HMOVE.BAT) useful for people who want to have seperate SD cards for horizontal and vertical games worked well for me.
