I'm opening up mine now because I'm bored and have the afternoon free.

Good luck! I remember someone asking to try and boot it up without the 2gig card inserted to see if it would work. Pretty sure Lectoid said it was glued in a bit as well. And of course, a .dd backup for posterity.

Unit doesn't boot without the sd card in. Blue Led comes on and thats it.

That glue REALLY has some elasticity to it. There is no way that sd card would have just popped out if you dropped it.

Well I think that's good news, should make it easier to get to the data. I still wish I had another microSD card to through something else on, like that linux distro that someone mentioned earlier.

I am d/l the forensic took kit thing now, it's taking over an hour. Meanwhile I still can't get anything to recognize the Ninja Masters SD card, at least windows and Mac. I am downloading ultimate boot CD and hoping that'll get me somewhere.

Hi there.

How do I convert .zip files to .fba files?

Thanks

You need to go to the official Dingoo Technology's site ---> http://www.dingoo.hk/en_main.asp

and download the A380 Neogeo Conversion Tool (Win32) from the "service" section.

Unzip the program, put your roms in the "roms" folder and launch "fbacache.bat". It will start to convert all roms in .fba format. I have had a lot of luck converting MAME roms with this program. H.G.

So it's just the roms in a game folder?

Try placing a new game in it and see if it runs?

Nice dude, now I don't have to take mine apart again. I don't know how many times the plastic can take it before the threads get mangled. How did you do it? What programs did you use?

Oh boy oh boy oh boy. If it's just a matter of getting a larger SD card and dragging in new roms... :buttrock:

I tried that software package linked in the thread but couldn't get it to work.

to dump it i just used: dd for windows (http://www.chrysocome.net/dd) and to look at the contents I used Ext2 volume manager. I haven't had a chance to tinker with it just yet. I'm heading out the door now (family stuff ugh) but I'm sure dumps will show up in this thread shortly. I'll check back in once I get home and if no one has injected any roms into it I'll try it.

Woohoooo! So when the SD is in and the system is on, plugged into a PC. You can browse a part of the SD card from the pc right? So maybe create a file from the PC, on the SD card. Then check in the SD image to determine where that files location is on there. Then, copy the sd "game" folder to that location and symlink it to the original location. Potentially getting us read/write to the roms directory without having to dissassemble the device again.

Another thing to check would be restoring that DD image to another SD. Making sure it boots. Maybe restoring it on 32g SD. Since the spec sheet says it can read them.

Holy balls! If the boot volume is on the card as well couldn't you just have this system boot whatever the heck set up you want it to?

So I found this today using a hexeditor for that sys_update_file. There's pages of this, I didn't want to post a hundred screen shots.

Well, now we all know all the proper romset/dir naming.

I can hardly wait for V-Liner (Set 2) to be released!! :P

So, what's hierarchy for loading up on the device. Is it possible to burn the image with added roms on a standard sd card and booting it all from there? Without opening the system?

Extract a rom and view contents to see if the .fba extension is simply a rename from .zip or .7z

Sort of relevant, but if any of you haven't been tracking the other thread, NG:DEV team seems to think that the crappy NGX video can be fixed on the software side:

It's mostly if not all software.

I see 3 main problems.

1. A wrong video resolution is used
The NEOGEO uses 320x224, but the NGX scales it to 320x240 and upscales it to 640x480 for HDMI.

Scaling 224px to 240px is a bad idea.
This also results in a 2nd problem that if you apply scanlines with a videoprocessor those are off.

Solution: don't scale to 240, just add 8px borders at top and bottom. Then scale pixel perfect to 640x480

2. The NEOGEO uses an odd video refresh rate 59.18hz, but HDMI requires 59.94hz

This results in tearing, no vertical sync possible.

Solution: speed up the emulation to 59.94Hz/60hz.

3. Sound lag.

Solution: Unknown. Probably just a bug, maybe hardware problems too?

Since the internal memory dd is being uploaded, can anybody upload a rip of the Ninja Master's SD?

Thought it was worth mentioning that the Open Dingux based GCW Zero shares the same exact cpu as the neo geo x. It had a small release and looks like it will have a larger release on kickstarter. Homebrew development effort should be able to be shared between the two devices.

I am booted in to Linux using the Ultimate Boot CD. I still can't get my PC to even recognize the Ninja Masters SD card. I've used testdisk and other partition software, It just doesn't even know it's plugged in. Maybe it's my PC
