Need help modifying 2 programs (source code included)

[LawnMeower]

Hello..
I am sorry if it appears a bit rude.. But unfortunately I don't have enough programming knowledge, yet..
The first tool un- and repacks .lz files from F-Zero GX. But it is unable to un- and repack .lz files from F-Zero AX. I get following error message: "std.stream.ReadException@std\stream.d<46> : not enough data in stream
47EA54
47E8CB"

here's the original program source: http://forum.xentax.com/blog/wp-content/uploads/2011/07/gxpand.zip
(its written in D)
I think it can be fixed in a few minutes.

The other tool is able to extract .gma and .tpl files from F-Zero GX/AX. But it can't repack them.. (the .tpl files can't be open with other .tpl modifiers)

here's the program: http://forum.xentax.com/blog/wp-content/uploads/2011/07/gxgma.7z
(written in c++)

tools are made by GameZelda.

source codes are all included.

(I'm also asking here because I think the creator of these tools stopped working on it)

I'd be so thankful for any kind of help T_T
