Firstly, this is not a rom request...

What the hell is going on with Mame Plus and the neogeo bios? I am using Mame Plus XT 0.126. First I encountered numerous errors with missing Uni bios files and the like. I managed to fix most of it by shoving bins into the neogeo.zip file. The only error I get now is a missing neo-po.bin. What is this file and where does it come from?

I have all Neo-Geo bios files that I know of (all uni bios and aes/neo cd bios files) but I cannot see this particular bin file anywhere. Is there some bin under a different name that needs adding to the neogeo.zip file? (After adding the files inside the aes bios I got rid of a differently named bin from the error list). It seems as though these games run but at the moment I cannot get the games to show up under 'available' as they won't pass audit.

Neo-Geo games pass properly in Mame XT 32 with the regular neogeo.zip but I wanted to try out Mame Plus. I cannot find any information anywhere as to what this elusive file is and why it is needed.

It's the Japanese AES bios.

Oh, OK. Thanks for the information. Where do I get it from (only joking).

That's what I needed. More information on what the file actually was.

EDIT: I just tried running a Neo game on all territory settings (US MVS, Universal, Asia AES etc) and the game did not run when I selected Japan AES. Obviously you are correct iq_132 - I find it strange that just this one file missing is enough to be categorised as 'unavailable' in Mame when I'm not even going to play the Japanese home version.

I just found the bloody thing (I would have never found it without the Japan AES knowledge).

All Neo-Geo games have now passed audit. Thanks a lot, couldn't have fixed it without your information.

2 hours of searching and then found it 5 mins after reading your post. Thanks again.

it took me a while to find those too

Im struggling to find the Japan AES BIOS (neo-po.bin) can you send me a PM or help me find it, ive been looking for days

Don't ask for BIOS files in any shape or form. I thought the rules were clear on this.
