Event Hacking question

are you speaking of his event in level editor or his "if set mem" address?

No, you're getting event bits and events mixed up. They are different things.

An event is, well, just what it sounds like. It's a collection of instructions and parameters that determine how a particular scene will play out.

An event bit is a binary value that's either set (1) or not set (0). The 'If mem set' section deals with event bits, not events. These bits are toggled on (set) or off (unset) in events depending on certain things you want to happen, at that particular time or later on.

For example, that's how the game knows who is available to put in your party. It checks bits related to each character every time you load up a party selection screen and populates it depends on the result of the checks.

So before my jump from opera house to blackjack scene I entered D0 00. Then i entered the the code pointing to blackjack scene.

At the end of my event (D0 7E D4 ED D4 FD) i added D1 00 FE.

I then went to level editor and set the Umaro event to 1E800 and the "If Mem Set' to address: 1E80 bit:0

I ran it and with the same results as all my other attempts. No Umaro, and everything freezes but the music after the "ante up" dialogue line.

I think we'd have to see more, including your jump and what you overwrote.
