Neo Geo Bios Download For Retropie

Neo Geo UniBIOS v4.0 Free For Personal Use Posted on March 20, 2020 March 26, 2020 by Bob The creator of the Universe BIOS for Neo Geo consoles has just made the latest version (v4.0 for AES/MVS, v3.3 for NGCD) available to download for personal use. To active, change the Core Option for Neo Geo mode to UNIBIOS. See Setting Core Options. Note that this will automatically use the latest version of the UNIBIOS avaialble in your neogeo.zip. If you want to select a specific version, use the BIOS Core Option, however note that this setting applies per-game, rather than system-wide, like the Neo.

Please check FinalBurn-Neo for for basic information about controls and managing ROMs - this page is for specific information about the lr-fbneo emulator's features.

Bios

lr-fbneo is a popular choice for the Raspberry Pi 2 and up, as it supports the latest FBNeo romset (v0.2.97.44), and a broad set of features. FBNeo also should always outperform MAME in the games they both support, as it is tailored for speed, rather than accuracy. Also, it is a libretro core, so enjoys all the benefits of that: centralised controller configurations, many customisation options, netplay, shader/overlay support, etc.

System menu

By default, if you hold the Start button for a few seconds, the ROM system menu appears. Here you can set various game options, typically including 'Free Play' modes, regional settings, etc. Settings are saved in .fs files in the ROMS directory for the system in use, and are loaded automatically on next use.

Dipswitches

lr-fbneo exposes all the dipswitch options of any given game as Core Options. See Setting Core Options. The dipswitches available will vary from game-to-game.

High scores

lr-fbneo will attempt to keep a permanent record of any high scores you set, but some games will not save these by default. There is a supplementary file that is automatically installed to your Pi that will enable high score saving for more games, called hiscore.dat. This file is the same as that from http://highscore.mameworld.info/ (labeled 'old format hiscore.dat (pre mame v0174)'). It is located in:

When high scores are saved, they are kept in the current rom directory as gamename.hi files.

Arcade layouts

lr-fbneo has been configured to use the SNES layout in six-button fighting games. That is:

So arcade stick should be setup accordingly.

Samples

Some sound effects in a few older (typically pre-1986) arcade games are difficult/impossible to emulate. Instead, audio clips of these effects can be downloaded and automatically played at the appropriate times. FBNeo additionally supports the use of some higher quality samples such as the CD audio rips from the console version of Donpachi. Samples are often included in a romset, or you can find some at http://www.progettosnaps.net/samples/. Place them into:

Neo Geo UNIBIOS

For Neo Geo games, you may want to use the UNIVERSE BIOS/UNIBIOS - an advanced Neo Geo bios that allows region selection, cheats, dip-switch control, and more. To active, change the Core Option for Neo Geo mode to UNIBIOS. See Setting Core Options.

Neo Geo Bios For Retropie

Note that this will automatically use the latest version of the UNIBIOS avaialble in your neogeo.zip. If you want to select a specific version, use the BIOS Core Option, however note that this setting applies per-game, rather than system-wide, like the Neo Geo mode setting.

Use the B button to go back to the Quick Menu and select Restart Content then Resume Content. You should see the Unibios boot screen before the usual 'Max 330 Mega Pro-Gear Spec' screen.

Instructions on how to use the UNIBIOS can be found here: Neo-Geo - Bios.

Neo Geo Overclocking

The Neo Geo system infamously has several games in its library that push the system beyond its original capabilities, causing slowdowns during busy moments. Metal Slug 2 is a particularly egregious example. With lr-fbneo you can - inauthentically - reduce and sometimes avoid such situations by 'overclocking' the emulated CPU.

Note: This may have undesired effects such as increasing the music or game speed.

Change the Core Option for CPU overclock. See Setting Core Options. By raising the number beyond 100, you increase the CPU speed.

Feature requests

I spent one year building an arcade machine. I found myself installing and reinstalling RetroPie on my Raspberry Pi a million times to get it right for the type of work I wanted to do. Every time I needed to reinstall, I had to reconfigure the entire system by following the same steps repeatedly.

Neo Geo Bios Retroarch Download

The reinstalling was mostly because of the lack of information about many setup choices you have to make if you want to get the most out of your Raspberry Pi.

Installing RetroPie

The first step is burning the RetroPie image into the SD card.

  • Step 1. Identify which model of the Raspberry Pi you have.
  • Step 2. Connect a compatible SD card to your computer.
  • Step 3. Download and install the official Raspberry Pi Imager.
  • Step 4. On the Raspberry Pi Imager, go to Operating System → RetroPie and select the version that belongs to your Raspberry Pi model. Also, choose your SD card.
  • Games: SD card or external drive?

    From here, you have two options: installing games into the SD card (efficient when your SD card is big enough) or installing them on an external drive (most ideal for small SD cards).

    If you prefer to keep games and RetroPie on the same SD card, you can avoid the section 'Setting up the external USB Storage'.

    To install games on an external USB drive, do not plug the SD card into the Raspberry Pi.

    • Step 5. Extract and reinsert the SD card into your computer.

    You'll notice the SD card is now called boot.

    Setting up the external USB Storage

    Keeping the games (ROMs) and the saved games progresses in an external source makes it easier to experiment with RetroPie in the SD card, keeping the critical data safe in a plug-n-play source.

    It's also a good option when you have a small SD card with enough space for no other thing than RetroPie.

    • Step 6. Format a USB drive as FAT. Use any disk utility available on your OS for it.
    • Step 7. Create a folder named retropie-mount on the root of the USB drive. It will be used by RetroPie every time you boot the system.

    Find more info about this in the official RetroPie documentation.

    Overclocking the Raspberry Pi

    If you have an old model of Raspberry Pi or a Raspberry Pi Zero,it is recommendable to overclock your board. That way, you can run games that require more power. For example, a Raspberry Pi Model 1 and Zero can't run most of the Neo Geo or MS-DOS games, but an overclocked Pi can do it.

    There are two ways to overclock a Raspberry Pi: the wrong one and the right one.

    The wrong way lets you expand the core and memory as you wish, but it's dangerous to your board and voids the warranty.

    Raspberry Pi provides an official way to do it right: Introducing Turbo Mode: up to 50% more performance for free.

    I recommend you to do it in the right way:

    • Step 8. Edit the file /config.txt and add (or uncomment if it's already there):

    Setting up an arcade controller

    It took me a while to understand how to set up an arcade controller. Even though the documentation is right there, I didn't know the arcade controllers' name was Xin-Mo.

    • Step 9. Edit the file /cmdline.txt and write at the end:

    There are a few more steps to configure the controller but wait until turning on the system.

    HDMI sound

    If you're using a computer monitor like me, it probably doesn't have built-in speakers. In some cases, this kind of monitor has a 3.5mm jack to output sound to external speakers. In that case, you may have to make that the HDMI takes control over the sound:

    • Step 10. Force the sound to go through HDMI by adding the following line to the file /config.txt:
    • Step 11. Increase the sound quality by updating the /retroarch.cfg file with:

    The headphone jack's sound is a lot clearer with a lot less static using that configuration.

    Now turn on the Raspberry Pi

    Plug the SD card and the USB drive into the Raspberry Pi and turn it on. As it is the first time to run RetroPie, it will take some time to process.

    The first screen to appear is to set up the controllers:

    Setting up the controllers

    • Step 12. Set up each button of your controller. For an arcade machine (Xin-Mo controller), I recommend using the same distribution as the Sega Genesis controller. For any control that you don't need to set, keep pressing any key to choose -NOT DEFINED-.

    You can change this later and also set up different controller distributions for individual consoles and games.

    The A button becomes the Enter key, and the B button becomes Escape.

    To set up the controller for the second player:

    • Step 13. Press Start to open the menu, then select Configure input, this time keeping any button of the second controller pressed.

    Installing games

    That was all related to the initial setup. Now it's all about games!

    If you followed the steps to install games on the SD, follow the official documentation about all the possible ways to transfer ROMs.

    To install games in the external USB drive and if you followed the steps detailed on Setting up the external USB Storage, then:

    • Step 14. Unplug the USB drive from the Raspberry Pi and plug it into your computer.

    Now the folder /retropie-mount should have some folders inside:

    ROMs

    All the game ROMs must go inside the folder /retropie-mount/roms.

    • Step 15. Place the ROMs into its corresponding console folder. Avoid zip files because they are not supported.
    • Step 16. Plug the USB drive into the Raspberry Pi and wait until the drive's LED stops blinking.
    • Step 17. Reset EmulationStation going to Start (menu) → Quit → Restart EmulationStation

    The ROMs are now on EmulationStation. You're going to see them in the main menu of RetroPie under the console name. Repeat steps 14-17 to add more ROMs.

    Specific setups

    Following the steps above, you'll have access to the most common consoles and games. But by following a few more steps, you can go beyond that.

    Sega Megadrive/Genesis buttons

    The Sega emulator recognizes only three buttons by default (Megadrive controller). In my case, I had installed six buttons in my arcade cabinet, so I activated all of the buttons (like a Genesis controller):

    1. Launch a Megadrive/Genesis game and go to the RetroArch menu ('Select' + 'X').
    2. Go to Quick Menu → Options and set the two input devices to six buttons pad.
    3. Exit the RetroArch menu.

    Neo Geo BIOS

    This emulator works a little differently from the other ones. Before copying ROMs, you need to:

    1. Get the Neo Geo BIOS: There is plenty of sites where you can find the neogeo.zip file you need.
    2. Copy the zip file (compressed) to /retropie-mount/BIOS and /retropie-mount/roms/neogeo
    3. Move ROMs as zip files (compressed) to /retropie-mount/roms/neogeo
    4. Restart EmulationStation.

    Note: Most of the games won't work the first time, but you can change the emulator for those specific games:

    1. Open a game and press any key before it loads.
    2. Go to Select emulator for ROM → lr-fba (or any other emulator) → Exit without launching.
    3. Relaunch the game manually.
    4. If the game still doesn't work, try the same steps with another version of the game.

    Visit this complete video tutorial for more info: How to Set Up And Use NEOGEO Emulator Retropie Raspberry pi 1 2 3 and Zero.

    MS-DOS emulator

    Beyond this point, you'll need to use a keyboard.

    1. Connect the Raspberry Pi to the Internet.
    2. Go to the RetroPie settings: 'RetroPie' → 'Retropie setup'. The first time getting there can take several minutes.
    3. Install DosBox: 'Manage packages' → 'manage optional packages' → 'dosbox' → 'install from binary'. It will take some time because it needs to download packages from the Internet.
    4. When it ends, go back to the main menu, then restart the system: 'Perform reboot'.

    Now MS-DOS is a console in the list of consoles. A new folder /retropie-mount/roms/pc will also be created automatically in the USB drive.

    Visit this complete video tutorial for more info: Simple DOSBox Setup RetroPie MS-DOS Raspberry Pi.

    MAME emulators

    I had the worst experience trying to understand this platform. I recommend to play arcade games on Neo Geo or find a version of the games for a more common console. In case you choose to use MAME, this is what worked for me.

    There are different versions of MAME that were launched in different years. So, for example, if you have the emulator for MAME 0.37b5, you must get games with the specific version 0.37b5. For some versions, the games are far more challenging to get than others. Another factor that determines which version you need is the Raspberry Pi model.

    • For Raspberry Pi Zero and 1, ROMs have to be version 0.37b5 (mame2000).
    • For Raspberry Pi 2, 3, 4, and 400, ROMs have to be version 0.78 (mame2003).

    Then to copy ROMs:

    • Copy zip ROMs to the folder /ROMs/arcade.
    • Do not use folders specific for emulators, like /mame-xxxx.
    • Upload compressed (.zip) ROMs. Folders won't work.

    The first time a game is running, it will ask for an emulator to run:

    • For Raspberry Pi Zero and Pi 1, choose mame4all (mame2000).
    • For Raspberry Pi 2, 3, 4 and 400, choose lr-mame2003 (mame2003).

    And

    That's all far I could go. I'll update this guide as I find more and better solutions.
