I have NO clue if it's still 2 byte, but back when I was playing this and used CheatEngine with it, I only had success with 2 byte values, searching for 4 byte values did not point me to the correct value I was looking for. Which at that time, was to cheat money.
The post where I state it's 2 byte is a reply to another person giving a short tutorial on how to cheat, where he stated to look for "4 Byte" values. All I commented was that you need to look for a 2 byte value if you want to cheat money.
Again, this post you are replying to is like 2 years old, so I have no clue if it's still the same case or if the developer changed their code so much that it's not 2 byte anymore.
Hope this clears up any confusion.
