Yeah, I don't know why though. It's a pain to sit there and sub every line of dialog and then have it checked over and some of them do a really good job of not killing all the original feeling or cultural references. Then they do all this elaborate stuff with the lyrics in the openings/closings.

By default this program should behave in a way such that a game made in RPG Maker 2003 could be played directly in 20XX without any problems, except hopefully with no more game-breaking bugs and agility being fixed.

You can enable all the advanced features for new projects or updating existing projects, but they're all off by default.

"What should I know as far as distributing the game for others to play"

Just delete HARMONY.DLL and RPG_RT.exe since you don't need those, and then add the contents of the download there. It looks in C:\Program Files\rpg2003\RTP for RTP graphics instead of finding out where it was installed if the user changed the installation directory, so to be on the safe side make sure all the needed stuff is in your game folder. FullPackageFlag in the .ini doesn't mean anything anymore.

"and what advanced features does it have (except for the ones listed/elaborate?)"

What I haven't already said is the VideoSize entry in the .ini. Add VideoSize to RPG_RT.ini or wcrpg.ini to set the minimum scale factor for your game. VideoSize=2 would force double size, and is handy when you're using double size images and you can't go any lower.

-2x will work for any file. Even the music file. All the -2x in the file name means is to use this resource instead of the normal one. It goes before the extension in all cases.

The game is being drawn in 3D. Well, it only looks 2D because I'm using an orthographic projection matrix and not using the Z value. However, I could modify the projection matrices and positions to implement "mode7" rather easily since it's already being drawn with your video card using the 3D video pipeline.

The same can be said for any shaders, I can apply .fx files to any of what you see. You'd mostly just want full-scene shaders like HDR/Bloom, blur, or other things. Normal mapping would only make sense in a few cases and even then you could just draw the tiles that way and have no shader.

If enabled, you can define where the args variable stack is located in your variables. I'm going to use this to implement syscall. You make arguments A, B, C, and D what you want, set the syscall code for E, and then write 1 to F in order to execute the syscall. Return values goes into F after that. Example:

Variables:
...
0034: A = 2 (Give me the HOUR)
0035: B = x (Don't care)
0036: C = x
0037: D = x
0038: E = # (Number for System Time call)
0039: F = 1 (Run)
...

Becomes:
...
0034: A = 2
0035: B = x
0036: C = x
0037: D = x
0038: E = # (Number for System Time call)
0039: F = 22 (For 10PM)
...

Since there will be plenty of additional event commands for you to use in this way. In this example, I had six blank unused variables starting at 34 so I set the argument base to 34.

Possibly. Only one way to find out.

Yeah, or \i[\v] to show the name of an item referenced by variable v. I'll implement whatever comes to mind with that.

Yeah, WeaponBirth automatically word wraps too. But here's the problem, when you make a multi-line message command it actually generates additional commands! I should probably insert spaces instead of line breaks when turning these into a single message, and then execute my word wrapping algorithm. This will break up dialogs written with return marks intended with specific return marks like this:

Person: Hello...?
...
...
HELLO!?

But I suppose it wouldn't be so bad.

That would get a little weird and messy though, because then you'd have abrupt lines with a single word because the previous line couldn't fit and now the fourth line gets shoved down. If I destroyed the line breaks and put it all together, you would only have to worry about a message that is simply too many words long. If you kept within the 4-line limit like you do now but ignore width, you should be fine.

Example:
I don't think we're alone out here, what do you think?
... ... ...
Wait, what's that?
Aaaaaaaaaaa!!

Could become:

I don't think we're alone out here, what do you
think?
... ... ...
Wait, what's that?

With the last line being a problem.
