Hacking NDSTokyoTrim - batch trimmer with wifi detection

[Duo8]

Yeah but as long as offset+size is below trimming it should be safe.

How are you implementing trimming right now? Last non-0 + 2MB?

 

[BrianTokyo]

I check specifically for Card2 roms.

I check specifically for Card2 roms.

Then what do you do to trim them?

 

[Argona]

Does this work with .3dz files made to go online with?

 

[Chrisssj2]

And now most importantly can I with this program SUPER trim batch a whole folder with roms? Meaning remove update data.

 

[OuahOuah]

Don't know if Brian isstill coming here but found something interesting here : http://gbatemp.net/threads/3ds-rom-tool-rom_tool.349314/

So basically, the other tool have source available
And :
- not trimming at all for "card2" type game
- can trim "normally" card1 games
- can "super trim" (remove update partition) for "card1" games

Maybe those differences can be included in NDSTokyo Trim like this :
- detect if a 3ds game is "card1" or "card2". If card2, tells it is not possible (recommanded) to trim
- if card1, check if "super trim" option checkbox is checked. if checked : trim normally + remove update partition. if not checked, just remove "normal" trim.

I think the other tool have internal database of card2 game but if not, I think it can be found elsewhere and could be added to an XML file in the same dir that NDSTokyoTrim and thus can be manually updated by user instead of waiting a new release compiled by Brian.

EDIt : found some "not card2" games listed here : http://wiki.gbatemp.net/wiki/3DS_flashcarts_game_compatibility (maybe a "do it at your own risks" message)

What the heck? I started the 3.0 released version of NDSTokyoTrim, put the GBA file (untrimmed) in there, and then I received this.

1. I have Windows 8.1.

2. I have DEP turned on for all programs.

Congratulations, 7 years on and still going strong!

I've been using this since the beginning and proven to be an invaluable tool.

Thank you for your continued hard work on it.

 

[MikeyTaylorGaming]

Awesome stuff! I used to use this tool back in the days of the original R4DS! Can't believe it's still going so strong!

Can anyone confirm that this works with .3DZ files? And works with both CARD1 and CARD2 types? Haven't read the entire thread obviously with 86 pages, but originally there was a problem with Card2 type not saving properly right?

Haven't got any .3DZ ROMs but plan on making a few, so if trimmed first can they still have new different headers injected? Thanks all!

Can anyone tell me if roms trimmed with this tool work on Sky 3DS? Tried searching the thread but no results. thanks in advance.
Used it on my dstwo in the past and found it very handy, surprised it got updated for 3DS.

Just recieved my Sky3DS, and updated to 9.5 and can confirm Roms trimmed with this tool still work fine on Sky. Tried tomodachi life, which asked for an update of the game first, and let me continue from its demo save.

I just discovered this today and it's just GREAT ! I trimmed the 25 roms on my GW and won several Gb

 

[d0k3]

Been using this with my M3 real back in the days. Nice to see it's still there! Will this also remove the system updates from 3DS game backups?

EDIT: Just seen it, it has already been asked. So, no supertrimming? I'd really like to use this instead of rom_tool - no offense meant to the developer, but I'm familiar with this one and would like to keep using it.

Is this still being atively developed on? After trying now, I get 'out of memory' errors when unpacking large roms (the 2Gigabyte Castlevania 3DS rom for example, I have 4GB of RAM installed in my PC). Also, the slowdown from having Tokyotrim unpacking in background is bad. Why not use the 7-ZIP libraries for such operations?

Also, an idea for CARD2 roms such as Animal Crossing: Yeah, you can't just trim them like the others, because then there will be no more room for the save file. However, as I read somewhere else (don't take my word for it) 3DS savegames are typically 1MB big. There are not that many CARD2 roms to begin with, so testing if 1MB is correct would still be in the realm of possibility. Now, if you know the size of the save, you could just trim CARD2 roms to their regular (CARD1) trimmed size plus size of the savegame and - voilá - you get to save space and still be able to play your games.

Hello. I have used NDSTokyoTrim v3.0 to trim some of my roms, but a few of my roms are not trimmed. Also, when it says, "SKIP: File already trimmed," it means that the file is not trimmed. Keep your eye on the file sizes.

See this image.

First, I dragged some of my roms to NDSTokyoTrim.

Second, I pushed the "trim" button, and here it is.

Two of my roms are not trimmed by NDSTokyoTrim. There could be issues.

Here is the log.

Again, I am using NDSTokyoTrim v3.0.

 

[masterz87]

Is there any plans to allow trimming of update data in the optiosn menu, sothat way I can use this thing? because as it stands I can only use rom_tool to do super trimming.

 

[DeriLoko2]

Does NDSTokyoTrim have "Removing Update Partition" support? I would love using that setting in order to trim roms.

 

[masterz87]

No, only rom_tool does, and this is likely because ti cannot be undone, and ndstokyo trim has always been about doing trimming that could be reversed.

 

[DeriLoko2]

Can NDSTokyoTrim have "Fix/Remove Overdump" support?

Okay. Here is what I did so far.

Here is NDSTokyoTrim and the GBA file (which is overdumped) that has 8 MB of size.

I dragged that GBA file into NDSTokyoTrim.

I trimmed it.

NDSTokyoTrim has trimmed 3 bytes of the GBA file size, but the GBA file size is not the actual size.

Let me try out another copy of the GBA file (which is not overdumped) I have used, thanks to GBATA (GBA Tool Advance).

Same steps.

And there. Did you look at the GBA file size now? NDSTokyoTrim has trimmed 18.66 KB of the GBA file size. I have found out that the GBA file size that was trimmed was the actual size.

I have another GBA file that was trimmed without fixing/removing the overdump. Do you want to take a look?

Did you see that? NDSTokyoTrim has trimmed 925.92 KB of the GBA file size without the option to fix/remove the overdump.

Do you find this confusing?

Again. Can NDSTokyoTrim have "Fix/Remove Overdump" support?

If you said to me, "No, it does not have the fixing/removing overdump support," I will not be happy.

 

[InfoFront]

Great program. It would basically be perfect if it had super trimming for 3DS roms.

 

[DeriLoko2]
