Precacheing?

How do you get an application to load all the data before the frame starts in MMF2? Kind of like the loading screen in WaDF.

Well, If objects are loading something, you could try closing off the game until everything loads.

There are lots of games that have a fake loading screen 

I love those fake loading screens. KS has a pseudo loading screen, actually.

Wow, I thought they were real. That's a little misleading Nifflas.

for example, R-Type's statistics

Some games pause while they're loading; for example, when you load resources in a Game Maker game, everything in the game will pause while it loads them. If MMF2 does that, then I find the easiest method to make a loading screen is to tell the game to display the text "Loading" (or something to that extent) and then load the resources, so that the loading message is onscreen while it's paused, and then goes away when it's done.

Alternatively, you could have it load each resource separately, and right before it loads each one, have it draw a loading bar, and make each consecutive resource increase that loading bar.

If you're game is that huge, you could just write a big LODAING on screen and then when everything loads it will disappear behind it, kind of like KS or the level editor's tileset.
