Some tools to solve LF2 related problems

[A-Man]

I am giving you thanks because you put effort in your program.
but whats the point of it?

The A-Grid Clipper:

just do it from start. its not much job.

Well sometimes you might start a project when you don't know you're gonna have 20+ characters later in the game, ergo start caring less about having perfect dimensions of the grid for you sprites. Plus people who work on mods usually have this 1 base where they start doing their characters from (to avoid dcing the basic actions every time). Now say your game is having different sized characters when even some of these tiny characters can have a move where his size increase of there with an effect attached to his body increasing the sprite's size. Now there is where you consider deciding "I will just use only 1 base for everything".

Also

which used that 800x800 grid,

you mean 800x800 per one frame?

.. 800x800 per a grid (not a square, a whole grid; a bmp).

he A-Frame Excavator:

maybe one good thing is that you can see unused frames but its not realy helpful for me actualy.

Well, "there is a time and a place for everything" ~ Professor Oak- Pokemon. It depends on what you are working on.. How many people are there do you think they are looking for that 799 frames exe because of their lack of frames? 399 frames is most likely enough, but its just that people don't use them all, simply because they are always looking for sequenced frame numbers. The other frames can be used as well, but they are just hard to find in a 2000 lined .dat. Now that's what the A-Frame Excavator is for.

Some problems are because with these mods. People overdoing everything.
They putting many characters.

When you are working on a mod which represent a story (mainly an anime), you will always be asked for new characters which are there in that story/anime.

too much effects.
just too much files.
and maybe when you packing everything in exe. that can cause it too.

Needed for the graphical quality. Required for characters to work. And if you were talking about the A-Bitmap mirrorer in your last point, then no. It doesn't cause any problems other than increasing the mod's overall size.
