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