Hacking NDSTokyoTrim - batch trimmer with wifi detection

[perkele]

Ok i'll give you a hint. In order to replace the current background you need to create an encripted one, matching the same encription I used, which is based on random seeds, distribute it across the exe in several areas (it's not embedded as a resource), and have the checksum of various parts of it match certain values that affect the final rom size and trimming process. No background = wrong trimming.

Nice, now you admit you took all this effort just to keep your background picture from being altered, instead of putting that time into making a skinning engine or an easy to make option to show or hide the background.
Smart move.

Seeing you as a rather new member, I strongly recommend you read this before this evolves into a flame war.

Yep, although I have no need to explain what I spend my time on or what I put effort into, to anyone.

At first I didn't care much about the background tbh, but seeing how people changed it I got some motivation to try and see if I could make it really hard/impossible to replace; as for people using other backgrounds I don't really care, but achieving this protection was a goal.

Part of this also works for the embedded DLLs, the libraries to extract unrar and 7z archives (not made by me). Other trimmers include them in the zip and stay in the same application folder. That can lead to people downloading fake libraries which are actually virus, so I thought embedding them in the exe and loading them straight into memory would be nice, and also convenient when taking the trimmer around, as you only need the single exe.

This technique for loading the DLLs into memory without previously extracting to disk seems to crash the app in Vista 64 though, so I might need to change that for a 64-bit Vista release. (the linked test doesn't have rar/7z support, only zip, for which I didn't require a DLL).

I never thought.. A japanese/chinese guy would be anime fan..

I'm western european

 

[Ducky]

BARNICLES! >.< Oh well..

 

[notimp]

Just dropping by to mention, that 0.75 still doesn't work with Win98. Still interested in a fix though.

 

[Grimalkin]

Er... who would stick with 98? Get an new O/S man.

Brian does good work, so no one should be complaining. As I said before, if you don't like it, don't use it. End of discussion.

Haha, awesome post. OK, knowing about the niftyness of NDSTokyoTrim's insides makes it quite cool

I'll go ahead and give it a try sometime. So far I've been using trim.exe in my SendTo folder.

 

[springah]

eggs!

sorry to offend, im just not "into" anime girls. anime in general is cool though. no reason to delay the bg change option because of me

but hey, great prog, use it all the time. just simply not a fan of anime girls who look 12 years old with hardly any clothes on.

Thank you soooooo much BrianTokyo for this superb trimmer and your quite interesting site !!!
I can't wait for the option to rename trimmed roms, this would make NDSTokyoTrim THE PERFECT NDS trimmer.

Could you please tell me the name of your signature's anime ?

Regards

 

[Shebang]

Is there a version without the background for non-paedophiles.

I second that ...

shebang

 

[BrianTokyo]

Sorry, that's a requisite

Scene numbers thing: most probably in the next version

Anime: it's "The Melancholy of Haruhi Suzumiya" (Suzumiya Haruhi no Yuutsu)

The App is great, but even ignoring the Japedophile background, The pic makes the text way too hard to read. Gotta pass until that background becomes optional.

The app double-backs as an eye examination.

I have absolutely no problems reading anything on it.

 

[Harley77]

A simple fix, Change the Color inside the Text Boxes.

Before

After

Tadaaa!

Then what's the point of having a background I tried my best to leave everything transparent.

I really wish someone would make a new skin for the NDSTT. >__> Im tired of seeing a half-naked anime chick every time I want to trim my ROMs. ;___:
