Well, I've not done the event system in 2k3, so no. But the event is almost entirely translatable. Just look at it in RMXP, and you should be able to translate it entirely, it's all just conditional branches and variables, or fork conditions I guess in 2k3. The only event command I used that is not in 2k3 (at least, to my recollection, is Control Self-Switch, and you can just exchange those for regular switches. I do not particularly want to write the entire event out in 2k3, but try to translate it to 2k3 and if you see any event commands you do not recognize, just ask me and I will tell you what the equivalent is in 2k3.
