i did this with 2 different cards a 4 gig and an 8 gig and the system didn't boot. i can browse the files fine on my pc but no go on the ngx. Maybe its because they are hc cards? the only none hc cards i have are only 1 gig.

Shit. I dont know anything about the different card types. SD card guru I am not. But if they are a different style than the stock one that is in there, it sounds like a solid possibility to me. dd images are block level copies of the disk, you'd think it would work.

Can we modify files on the stock sd internal filesystem and still have it boot? I'd like to add the following line to the /etc/inittab
Code: 
tty3::respawn:/sbin/getty -8 38400 tty3

boot it in the dock with a keyboard on it, then do "ctrl-alt-f3". With any luck, that will pop a shell.

Yeah seriously, when i picked up at gamestop they were like wtf is this neo geo thing? Of course this is coming from a 19 year old female gamestop employee so I doubted she was alive when this thing came out.

Hello,

Yes, we can. I spent a few hours tinkering with the SD cards partitions and files yesterday, especially the bin and dge files in the /local/snk-desktop folder on the first ext3 partition (did anyone notice the leftovers from the factory test there, e.g. the images used to test the display? ;) ). I will try to bring up a shell this evening, when I am home again.

Also, mind that most files, e.g. in the config folder, have a second file associated containing a MD5 checksum - e.g. snk.conf and snk.md5 in /local/snk-desktop/config. If you alter a config file without updating the MD5 in it's counterpart, the system won't boot. Just do "md5sum filename.cfg" and edit the MD5 file to fix that, though.

Btw, it seems that I messed up one of the files invoking FBA when selecting a game; I can get my unit boot to the SNK desktop, but once I select a game, it just crashes and exits again. Would anyone be so kind as to send me an archive with the files from /local/snk-desktop (and its subfolders) so I can do a file comparison to fix that?

Cheers from Vienna, Austria.

If I remember correctly the actual emulator is Ngu.dge or named something similar in the /local/snk_destop folder.

I removed it once and had the same issues you are explaining. You propably just have replace that file.

Are all of the Dingoo emulators .dge? Wonder if swapping the roms for another system would work if you swapped the emulator as well.

Yes they are. I haven't tried swapping the emulator with another emu. In theory it should work. Even if the original emu has a md5 associated with it you could always change that. I did get a cp2 rom to run on the original emu but it didn't have video and the sound was really distorted.

My problem is I don't have a lot of time to tinker with this thing. I'm lucky if I get an hour a day so I'm just providing what I can when I can.

I have NO fuckin idea what's going on in here... all i can say is that at least there's no rom posting...

...haxxoring is OK.... some of my best friends here have managed to fook up their NG X to try and be the first to get it working properly... I'm impressed by the dedication and stuffs...

...Keep it up...

PS. Is it me... or is there an large proportion of people i don't fookin know posting in this thread? It's like the n00bsville Twilight zone in here....

For those that have pulled their units apart, is there enough room in the unit to replace the thumbstick with one from a NGPC?

That was the sort of crappy post i'd expect from a longtime member called kernow...

ie. Makes no sense and I feel it's just trying to add to your post count...

So this post won't get lost in the coming drama, I'm quoting myself.

Hopefully this thread isn't about to get derailed....

LOL, no problem. I have a feeling that since this thread seems to be linked all over the net in every story about hacking the X that the silly posts are going to increase all throughout the forum as we get more new members...


And for what it's worth, after actually looking at my NGPC and the X, my idea was dumb...

But I am on vacation... It's not like I post links to roms... besides, if we're gauging a member's post count and join date as a level of n00bness, that's silly...

I'm not gauging you on your post count... on your join date etc etc.....i'm not that sort of mod... ask around...

I'm gauging you on your contribution to this site...

The post you replied after mine said you didn't think about who you were replying too... or what... this is a thread about learning about a new system...

i don't care if you didn't post roms on here... i care that you posted a comment that didn't belong...

I won't derail this thread... but if you post again.. better make sure it truly adds to the current thread... i'm not in the mood to play ball... and you won't be missed...

Last warning...

hey, if I open this thing up, is it easy to get between the outer glass and the screen itself?

there is a piece of dust on the inside of the unit that is driving me fucking crazy...

Hi

Finally got a microsd card reader/writer this afternoon and was able to poke the device and to get some more info. My test microsd is a 16G SDHC card with the stock image dd'd to it. I still working on direct access into the device, the following output is from running scripts and redirecting the output to the 1g fat partition.

Here is the dmesg output with nothing hooked up.

So it would seem there maybe sometype of decryption going on in the kernel. But since linux is gpl someone could probably nag them for the source code ;)

I doubt they'd give up the source. But since the Neo Geo X is able to access these cards, how about making it make the dumps/modifications itself?

Ack, think you'd be able to make it get us a full dd of the Ninja Masters? Methinks the previous didn't contain the boot sector/partition table.

I've been following this thread closely and I have to say "great job" to all who have and continue to contribute to the effort of hacking the neo x. I would like to ask if all the work thats being done is being done on all versions of the neo x or only the 3.37?

Anybody care to post translation/ cliff note? I know what it does, just don't know if roms have to be same size or smaller then ones being replaced, are we still limited to 20, etc, etc...

I wish the video showed them getting loaded onto the X and launched...

Anybody care to post translation/ cliff note? I know what it does, just don't know if roms have to be same size or smaller then ones being replaced, are we still limited to 20, etc, etc...

I wish the video showed them getting loaded onto the X and launched...

You're still limited to 20, the romlist is located in binary. I'm guessing all this is is a GUI version of the A380 tool.

What is the OS requirements for the program? Looks like Linux or OSX. If that's the case, I'm hosed till I upgrade some home computers...I'm still running 10.4 on the Mac and haven't had a Linux box since RedHat had their IPO and Loki was still alive...last distro I used was the commercial ver of Suse around that same time frame...ah, the memories and the frustrations...
