All right, so that workaround seems to be working for you more or less?
But thinking this in the long run, it's going to be really impractical. You're not going to ship a Gamebooster or SmartRAM program if you distribute the game to other people. That's just more unneeded program bulk. No one wants that, really (Okay, at least I don't want that

).
Another anti-lag script won't help. Refer to my previous anecdote. Besides, ABSEAL has all you need, technically. :S
You're best off finding other ways. Question yourself this... Do you think you have too many enemies, perhaps? Maybe you can remove a few, or you can even have a sequence of enemies appearing. This way it doesn't need to be one giant orgy of events that can slow the game down.
