BLF Splitter and Merger

Ever get bored of having to extract a usermap from a CON file to edit it with sandbox, then have to put it back in the CON file again?

Not any more!

With the BLF splitter and merger, extracting and injecting BLFs is made easy!

Some examples of BLFs are maps, gametypes and film clips inside Halo 3 CON files.

BLF splitter and merger is attached to this post.

Cool! Nice work.

Very useful!

Not only does this take forever to extract a small file, it doesent even extract files larger then 696320 bytes properly!

I tend to use it solely for usermaps and gametypes...

And it's not my fault your computer is slow! Buy some more RAM

It has nothing to do with the RAM probably...I didn't take a look at the application and of course neither of the source code but I'm pretty sure you used a loop inefficient.

Loops have more or less a fixed cycling time, which can be speed up immensely if you copy the code inside the loop multiple times.

Code: Select all

for (int c;c<=Size;c++)
{
Br.BaseStream.Location = c
Br.Read()
}

(I know the code is incomplete)
This would take forever...this though would already be five times faster.

Code: Select all

for (int c;c<=Size;c++)
{
Br.BaseStream.Location = c
Br.Read()
c+=1
Br.BaseStream.Location = c
Br.Read()
c+=1
Br.BaseStream.Location = c
Br.Read()
c+=1
Br.BaseStream.Location = c
Br.Read()
c+=1
Br.BaseStream.Location = c
Br.Read()
}

Ugly coding...but you get the picture.

I take everything back if this is not the case in your application.

Ah. I know what the problem is...

I wrote this in VB for some stupid reason

VB is crap. I should've done it in C++

That has nothing to do with it. If you plan on using C++.NET it would be no faster, as all .NET languages are all compiled into the IL and use the same CLR.

anyone that knows a thing or two about the STFS file system would know thats not how they work...

Yea well he did't take the hash tables into consideration nor does he care so it doesn't matter now.

I must have been so stupid to not include full source code to proof my point.
You just wanted to find something to bash on.

Like LuxuriousMeat said, if you mean C++ compiled inside the .NET environment, all languages in that particular environment get compiled into an Intermediate Language called IL.

There are just some fine differences between the compilation of the individual languages into IL which, in this case, don't affect the performance (almost) at all.

If you don't take the hash tables into consideration you will never be able yo extract or inject a file larger then 696320 bytes.

Grimdoomer don't just ignore Anthony proving you wrong. Learn off what he's telling you.

What is everyone argueing about?

I made a program to extract forge variants and screenshots. It works. End of

So what if I didn't make it excellent! I don't really care if it doesen't work for files bigger than 696320 bytes; If you can find a BLF bigger than that, then more power to you
