Metal Slug 4 unable to inject unibios or original bios files

[dial]

I have received my NGX Tools and the MetalSlug4.mvs that comes with it works great.  I want to inject unibios into various games and I have been successful with the other metal slug games and various other games.  

When try to inject the unibios into mslug4.zip from a Final Burn Alpha collection the rom loads to a black screen for 10-15 seconds then kicks back to the menu.  I have tried Unibios 3.0, 3.1 and various different country neogeo bios' but no luck.  I have sourced mslug4.zip from various FBA collections and they are all result in the same.  

I would call it broken except for the fact that the NGX Tool's .mvs file does work even though it's not unibios enabled so it is possible.

Any ideas?

The ROM is corrupted. You need to find a different ROM set.

I've tried quite a few different versions, I'll keep looking. Applying to mslug4nd.zip doesn't generate anything. The funny thing is that I applied fbachache.exe the 421kb zip of ms4plus.zip and it generated a working rom with unibios enabled.

However it is the undesirable Metal Slug 4 plus hack obviously.

Tell me about it. Took me ages to get Metal slug 4 Plus and 6. When you get them feel free to use my custom 3d box art i made.

I have recreated stock icons like the 500a and jailbreak defaults, but im looking at a donation on these for the work involved as no one in the world has done this yet to my knowledge.

Got it working with CRC checks and luck. It's defiantly a non-standard setup and naming in the ZIP. =)
