Is a BIOS file required for this system? I didn't see anything mentioned on the GitHub page. If so, does it go in the same folder as the games? I can't seem to get the Power button to work using Start on my controller or the number 5 on the keyboard. Was wondering if a missing BIOS could be the issue.

The NGP Power Button is mapped to your "Coin" Button (if you mapped it manually to your pad). No, you don't need a Bios. Using the Power Button gives you a plain white screen. Just load the Rom then.

I had created a MGL file to link the RBF in the Arcade folder so I could access it in the Console folder instead. It seems like that must be breaking something. I think this particular core is unique because it depends on a MRA file. I wonder if there is some other way to get the MGL to work?

I don't know. Jotego built is obviously around his arcade cores structure. A bit strange, since it's a normal portable. Probably for own convenience reasons.

I can appreciate that. After doing a little searching on this site it seems as though arcade cores can't use the MGL file to create a link. A symlink has to be used instead. I'll have to do a little research on that as I've never created one of those before.

You can always search “man ln” for more info as I don’t believe the man pages are included in the MiSTer build.

Links are way easier IMO

If you happen to be in the folder you want to put the link in;

ln -s /full/path/to/target.mra

Or;

ln -s /full/path/to/target.mra easier/ to/ read/ name.mra

Which is equivalent to;

ln -s /full/path/to/target.mra “easier to read name”.mra

Or;

ln -s /full/path/to/target.mra /full/path/to/where/you/want/EZ4U2C.mra

Or;

ln -s /full/path/to/target.file /full/path/to/target/folder/

If you don’t supply a name for the link the original target name will be used.

I don’t like deleting links because of old problems and prefer to use the command;

unlink

Also this all assumes you can SSH into your MiSTer or have a keyboard attached. I’m not sure if you can create links via FTP as it’s been decades since I’ve used it.

Thanks for the information on how to create those links. I can SSH into my DE-10 and navigate to the _Console directory where I want the symlink. Should I be creating a link to the jtngp.rbf core? If that's the case, would this command work?

ln -s /media/fat/_Arcade/cores/jtngp.rbf

sorry... I hadn't had my coffee yet, those were supposed to be MRA files.

You would want to link to the MRA file

ln -s /media/fat/_Arcade/"NeoGeo Pocket".mra

or

ln -s /media/fat/_Arcade/NeoGeo\ Pocket.mra

You will probably also need to link the cores directory into the folder as well, sometimes the parent directory will cover it as well

ln -s /media/fat/_Arcade/cores

I'm not 100% on that as I haven't tested with anything but arcade cores.

Very confusing that the core goes into the arcade folder.

No worries. I actually ended up using Wizzo's Remote app to make the symlink. He made it super simple.

Arcade Cores

Arcade cores cannot be launched using MGL files. If you want to make a shortcut to an arcade core elsewhere in the menu, you'll instead have to symlink (symbolic link) it there.

For example, either through SSH or the console (press F9 from the menu):

Code: Select all

# ln -s /media/fat/_Arcade/dummy.mra /media/fat
# ln -s /media/fat/_Arcade/cores /media/fat

This would make a shortcut to an arcade core in the root of the MiSTer menu. It can also be done with menu subfolders.

Take note of the second line, symlink'ing the cores folder. You have to do this once for each folder you want to symlink MRA files into.

is all the information on the page concerning the subject. There may be more somewhere else, I just didn't find it.

and the roms go in

/media/fat/games/NGP

but it is not case-sensitive so you can also use

/media/fat/games/ngp

I think i am misreading something or being stupid, but I am having a hard time figuring this out

Where does the RBF file go? Under Arcade or Console?

Some guidelines on the folder structure required for this core would be greatly appreciated

update all downloads it to the correct location. Its in the arcade directory but needs a directory NGP created in the games directory for the roms

It shouldnt be in the aracde directory but JT cores all go here and so its misplaced.

Thanks! This has been most helpful.

I thought this was still beta and non responding to controls all this time because the inital bios boot doesn't do anything — I guess it is but the first ordeal to test your motivation to play that console.
It was only after reading mike911's message yesterday (thank you!) that I was able to to get...
to the point Jordi was, with white screen after setting up options...

I finally got a game to load, but oh boy:

When first launching the core, you have to cycle the power on/off with the "coin" (???) key as mike911 told us.
Then go through the bios settings.
Then you have to load a rom file.
Then cycle the power on/on with the coin key again (do not "reset" from the MiSTer menu, or you'll have to redo it all!)
Then hopefully play the game with some glitched audio.

Frankly, it being lost within the arcade folder feels pretty ideal, given how counterintuive it is to get to work (did I thank mike911 already?).

Ah, yes, you can't load another game right away.
If you wish to load a new ROM, you have to hit the reset in the menu, and go through the BIOS set up dance et all once more.

Boggles the mind.

Nothing happens when I press the COIN button, even after manually defining the buttons for the core

I uploaded ngp.zip (containing both ngp_bios.ngp and ngpcbios.rom) in /fat/games/mame, but I still get the message stating the bios not found when I load either ngp or ngpc core.

it should be in /fat/agmes/mame

It should be in /fat/games/NGP for the B+w

Is NeoGeo pocket color working on Mister fpga? It seems only working on pocket fpga.

Not for me

On one of his latest Patreon posts, he said that he moved it to Consoles from Arcade btw
August 30 posy
"JTNGP core renamed to NeoGeoPocket and moved to consoles folder."

Anyone had any luck getting the B&W version going? I just get a white screen - the roms load but they don't run.

I will in some days get my mister allready set with all up. But my question is how can I add more cores likes this Neo Geo Pocket and othe ones in the easiest way?

Read the documentation thoroughly, watch the video below and using update_all will download everything you need (except for the ROMs). Jotego's beta cores require you to be an active Patreon supporter to use. Once they are out-of-beta they are free for public use.

I bought an already set up mister. Do I in the future just need to update all? then all new updates will be there? New cores and so on?

I would still read up on setting up, running and updating your MiSTer. Running update_all will keep you up-to-date and can be configured (press down when prompted on running the script) to download additional cores and much, much more.

Have you got any chance with it? I'm stuck at the same stage than you.

Also stuck, same thing. Have a bunch of ngc files in NeoGeoPocket directory in /games.

I pick one from the OSM and loading completes but stays on a white screen.

I haven't come across any official instructions but....
I put the Neo Geo Pocket bios in the /games/NeoGeoPocket as boot0.rom.
I haven't played much with the NGP Color bios but you can use that one instead.
There is a chance the bios file(s) were downloaded and put into the Mame folder at some time...should be in a ngp.zip file.
