Hacking NDSTokyoTrim - batch trimmer with wifi detection

[Grimalkin]

I don't see why people are complaining about the background, you'll see it for what? tops 1 minute at a time then you close the thing.

if you don't like it, don't use it. QFT.

 

[BrianTokyo]

Thanks

Is anyone using Vista 64-bit? I got a report about the last version not working there for a user, I wonder if it's happened to other people too.

 

[Codekingmss]

I noticed something odd. It noticed trims that were too long by 136

[BrianTokyo]

Those that trimmed by 136: they were probably trimmed with other trimmers (or a very old version of mine) and included the wifi block for safety.

My trimmer analyzes that block of the rom to determine whether there is wifi data or not. (if not, then it trims that "safe" block since it's not needed)

 

[Ricoboy]

Hm, seemed there was a problem with de normal 0.75 release of this program. Must have been since I got a 64 bit version of Vista. Thanks to BrianTokyo he gave a link to a test version of a 64bit version of the app, that can be found at:

http://www.techsuki.net/64NDSTokyoTrim.exe

 

[GH0ST]

Thanks for the soft work ^^ Finally this 1 bit trojan protection is quite funny ;-)

( works well including update button thanks again ...till got error box for full disk warning and the trimmer is stuck with Halt Requested. Stopping Operations...

Thanks... Don't be rude with the pianist please

 

[chuckstudios]

I can confirm bricker detection works for both r0mloader and taihen.

 

[BrianTokyo]

Thanks for the testing and feedback

Note about the 64bit test: no rar/7z support. (zip works)

 

[BrianTokyo]

( works well including update button thanks again ...till got error box for full disk warning and the trimmer is stuck with Halt Requested. Stopping Operations...

Ah damn, I forgot about that. I'll add a check for that in the next version

QUOTEI can confirm bricker detection works for both r0mloader and taihen.

Thanks for testing

It's only a basic brick test though (applied automatically to every rom, either trimmed or not).
A more advanced through check will come in another version (much slower)

 

[Maikel Steneker]

There's no such thing as a "trojan", it's a self-protection, not just for the background, but for any modification done to the exe; if you were to download the trimmer from a torrent or anywhere else than my website, you have no clue what you are getting; (I've found it in several torrent and other download sites, even though I don't even require a registration for downloading it from my website)

Think for example about the embedded DLLs for unrar and 7zip, someone could replace them for viruses and you'd never know. So the trimmer detects any modifications from the original exe and shuts down as a safety measure. (just like antivirus applications do). The check is done before anything else in the exe is loaded, so in case you would download a version with an embedded virus from some unsecure source, the application shuts down before anything else is executed.

If you think that's a bad feature, /shrug. This protection has been in the trimmer for a long time, and someone found out when they uncompressed the upx packing (for what purpose, I don't know, but go figure)

My program, as suplied and used as intented, is completely harmless (not like a reboot does any harm anyway).

Although I don't fully agree with you, I think that's a fair reason

And, as mentioned earlier, you have the right to do so.

I'm glad the trimmer doesn't do any harm. You had me worried for a while...

[ZAFDeltaForce]

Brian makes perfect sense to me. And guys, you can wait months for Zelda: Phantom Hourglass. Why not just wait a little longer for that background change?

Its already nice of Brian to program one of the best ROM trimmer around. Cut him some slack guys

 

[Codekingmss]

The program is awesome. Also, thanks for answering my question so quickly.

 

[OSW]

But apparently you had enough time to put a trojan horse in it (windows shutting down after uncompressing the file with upx)
Why not release a version with and without the background that makes text unreadable?


What the fuck are you talking about? The trimmer reboots your computer if it finds the exe/background has been altered (when you run it). How is that a trojan?

A trojan is a piece of code hidden inside a program that performs another action than what the program is supposed to do.
wiki

What will be the next thing you're gonna put inside the program, make it delete stuff from the hard drive?

ROFL ROFL ROFL massive pwnage

Please brian, never change the background or include other options (unless they are miharu too

)

 

[matriculated]

At this rate you guys will never see the background change because you keep pissing BrianTokyo off. He already said he was working on it and it was working in the beta but ppl are still complaining. If you don't like the background - don't use it. If you think it has a trojan - don't use it.

 

[DarkAura]

I like the background...

It's nice, but I wouldn't mind a different one.

 

[Rayder]

The background doesn't bother me in the least. I don't love it, nor do I hate it. I consider it a trademark of Brian's work. Seeing anything else in its place would be strange at this point.

All I can say is that this trimmer is a great asset to flashcard owners and complaining about the background seems kind of frivolous to me. Not that I don't understand where some with conservative parents are coming from, but really, it isn't THAT bad.

I think complaining about it is doing more to prevent him from changing it than just letting B do his thing with the program at his own speed.

I think a simple solution is an option to have the pic or a basic plain background. That would be simpler than trying to create protection for many different pics. Just my opinion.


Whatever Brian ultimately decides to do is fine with me though. As long as it trims my ROMs for me, I'm good.

Rock on with your bad self, B.

 

[enigmaindex]

I hope he never changes it, just to piss all the people off that keep bitching about it. Haha

. Don't like it don't use it.

 

[BrianTokyo]

okay i am going to spend nights and day to change the background no matter what!!!! i pretty sure i can do it

and no i wont release it so brain wont get mad

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.

Good luck!

everyone else: thanks for your support and backing

linux/wine: hopefully fixed in the next release (can you test teh 64bit version linked in the previous page?)
