[Other] How do I Expand the Item Tables?

[VeryBestRogue]

Hello as you may have guessed my question I need to expand the item Tables.
I saw this thread https://www.pokecommunity.com/showthread.php?t=355985
and then moved the data to free space, then there was that routine i tried to compile but it didnt and gave me some errors. Then there was the word change at some offset, but what do you exactly mean by 'Word' change ??

Please Help...

A word is 4 bytes. So basically since you're not going to have that many items, change the bytes to XX XX 00 00 where XX XX is the number of total items in hex, in reverse order.
