Menu GUI/ item slot questions

[Jabba]

I havent seen any modifications of the Start menu and was wondering if it was possible? I've seen some of the textures modded but havent seen anything beyond the original grid layout. I was also wondering if you can any additional item slots, say for example adding extra swords, shields and tunics or do you have to sacrifice something for something else?

By the way the game seems programmed this appears to be a highly difficult matter. The items are stored simply enough  but right after items are important various bytes which if pushed or moved would need relocated by many, many different addresses.

 

Now in theory it may be possible to have different items occupy different spots in the Menu, but there seems little way to actually add slots to it.
