Retroarch FBAlpha Neo Geo Service Menu?

[subatomic09]

I'm trying to access the service menu through FB Alpha in Retroarch so I can turn the blood on in Metal Slug. Got the option set up to UNIBIOS, but I can't seem to get into the menu. Any help would be great! Thanks.

Do you get this screen when you boot a game ?

If you do then just press the 4 buttons you have set to A B C and D all at the same time at this screen and it will take you into the config screen.

Thanks @Lordmonkus, it's not working for me. I do get that screen, but pressing all four buttons isn't launching the menu.

Don't know what to tell you other than it works for me and that is the way to access it, I would only say double check you are actually pressing the 4 buttons you have set to A B C and D.

Make sure you hold the button combination while booting a game and during the splash screen. In game you can press Start + Select to access another menu for cheats. Here's some more info:

Ok, I got to that screen, but switching it to Japan/Arcade or Japan/Console doesn't change the blood from gray to red. Do I have the wrong rom?

 

Edit: Figured it out. I then needed to go into the Hardware Menu and turn blood on. Thanks for the help, guys.

Glad you got it sorted. I did the same for Metal Slug
