Hacking Rom Trimmer?

[HyoImowano]

I would like to trim my ROMs, but I do ALOT of download play (most of my friends don't have flash carts, but I've flashed all their firmwares) so I was wondering if there is a specific one anyone would recommend for keeping download play intact, or if it really matters. Thanks!

IF you have an R4, the installation disk should include a ROM Trimmer. And trimming ROMs do not remove any aspect of the game, but get rid of some dummy memory. Every game is made so that they are either 8, 16, 32, 64 or 128 megabytes big. They are not exactly that size, and the ROM trimmers just shave off that extra memory.

You can just download it from http://r4ds.com/download-en.htm ( At bottom of the page)

I DO have an R4, and I saw the standard ROM trimmer that came with it, but I remember that trimming some ROMs on my M3 Perfect would break download play, which is why I ask.

NDSTokyoTrim leaves wifi intact.

I was worried about it getting rid of good stuff too. I trimmed one game that went from like 16kb to 5kb.

kb? You mean MB?

Use that. It's the most updated at this point and works well. You can do batches of ROMs, not just one at a time. It detects WiFi data and will leave all that data intact. It can trim ROMs from within zips and rar's too. The dude that makes it (DSTrimmer here on the forums) is planning even more features in future updates.

I've been using it since the R4 team fixed download play.....it has only gotten better with updates. I highly recommend NDSTokyoTrim. It hasn't failed me yet.

My GUI also does batch-trimming but also gives you the source code in Visual Basic .NET so that it is clear enough to reproduce in your own apps.

It's nowhere near as featured as NDSTokyoTrim but it is a clean, quick, second-generation method with fully-commented basic source code.

Go on - give it a go and slap a shortcut in your SendTo menu.

Yeah, I guess I meant megabytes. I meant 16,000 kb to 5,000 kb.

That is a HUGE trim, use NDSTokyoTrim instead.
