Resurrecting the Amiga on the Raspberry Pi

I’m a fan of retro gaming and preserving the pc historical past that lead us to the place we’re as we speak. I believe most programmers have a machine that helped develop their love for programming; for me that was the Commodore Amiga. I’m at present restoring a few Amigas to get them again to working order. This will take me a while, however I wished one thing I might stand up and operating shortly so I can play with the OS and end a few video games I by no means accomplished as a child.

When I began working at Red Hat, I discovered a passionate group round retro methods and particularly the Amiga. We have a breakout room in our head workplace devoted to previous methods, and my fellow Red Hatters have donated video games and consoles to it.

Can I put an Amiga on that?

As a Linux fan, I usually discover myself some obscure little bit of hardware and considering, “I wonder if I can use it with Linux?” or extra usually, “I wonder if I can put Linux on that?” I blame my youth of taking part in journey video games and fixing puzzles for that mentality. Recently, I assumed, “I wonder if I can put an Amiga emulator on that?” This article is the results of a weekend spent doing simply that. It is not at all a whole information to all issues you are able to do with emulation for the Amiga, however it must be an excellent begin to get you going. I will present hyperlinks to all of the software program and go over a few of the issues I realized on my retro weekend, in addition to some guides to take it to the following step.

Here are the gadgets I received Amiga emulation to run on:

  • Lenovo 500e Chromebook
  • Nexus 7
  • Raspberry Pi
  • Samsung Galaxy Tab 10
  • Ubuntu PC
  • Windows PC

Amiga emulators

UAE is an open supply emulator launched in 1995. The acronym initially stood for Unusable Amiga Emulator, however now it is typically referred to as Universal Amiga Emulator, Ultimate Amiga Emulator, or Ubiquitous Amiga Emulator. Or extra merely, UAE. Most of the emulators for Android, Linux, Chrome, MacOS, and Windows are ports or forks from this challenge or grew from the emulation group. I additionally use UAE on my Chromebook, which helps Android apps, to emulate my Amiga.

I want FS-UAE, which is on the market on plenty of platforms. On Crostini (Linux on Chromebook) or Ubuntu, you possibly can set up it with the command:

sudo apt-get set up fs-uae fs-uae-arcade fs-uae-launcher

A caveat on Chromebooks and Crostini: Chromebooks do not but assist audio on Linux apps, however it’s a function that’s coming in ChromeOS 74. I want Linux-based emulators, so I’m utilizing the Amiga Forever Essentials Android app for now. I even have the Linux app put in, prepared for when audio and GPU acceleration for Linux apps change into out there.

Amiga kickstarts

All the emulators I used are open supply. However, with the intention to run any Amiga software program, you want a kickstart ROM that’s copyrighted and solely available under license. You should purchase one from Cloanto and they’re bundled with Amiga Forever. To stand up and operating shortly, you should purchase the Android app Amiga Forever Essentials, which was solely $1.99 after I wrote this. If you might be an Amiga fan, it is value shopping for Amiga Forever, because it accommodates a wealth of demos, video games, and pre-configured methods and has the whole lot you could possibly need to emulate a whole system.

The FS-UAE emulator can scan on your set up CD of Amiga Forever and mechanically copy the kickstart ROMs to their very own configuration folder. On my Ubuntu desktop, FS-UAE creates configuration folders underneath Documents.

Amiga on Android and Chromebooks

Setting up the emulator on my Samsung Tab 10, Nexus 7, and Chromebook was easy. There are plenty of emulators for Android, and in the event you purchase the Amiga Forever Essentials app, it’ll set up the business kickstart ROMs to a shared folder that the emulators can entry. Just obtain an emulator and you might be prepared to begin configuring your system.

The Amiga Forever Essentials app works on Android with the UAE4Droid and Uae4arm emulators (I want Uae4arm). One benefit of emulating the Amiga on Android is controller assist. I take advantage of my 8bitdo controller on my pill and it really works with no fuss. 8bitdo works effectively on RetroPie however might be unreliable via Bluetooth on the Amiga distros Amibian and Weight-reduction planPi. I want a controller with a dongle or wire, because it minimizes lag and works each time.

Amiga on Raspberry Pi

For the Raspberry Pi, there are two devoted distros for Amiga: Amiberry, operating on DietPi, and Amibian. Or you possibly can set up your emulator of alternative from the usual Raspbian repo; you aren’t restricted to both of those choices. Configuration is sort of equivalent on each. I attempted each, and my desire is Amibian, for no different causes than it is nearer to Raspbian, I’m extra comfy with it, and configuration is effectively thought out. Both distros are very lean and do not include lots of packages to “bloat” the set up. They typically use SDL to run without having for a window supervisor or operating an X Window session. They are quick as well and lean on assets. Perfect!

Hardware

Getting began

The first step is putting in Amibian. Download the disk picture from the Amibian website—click on Download from the menu and save the file to your machine.

Now, flash this picture to the MicroSD card. The simplest way is to make use of Etcher, which is available on Linux, Windows, and MacOS.

  • Download and set up Etcher
  • Put your MicroSD card into your machine
  • Start Etcher
  • Select the unzipped picture file you downloaded from Amibian
  • Select your MicroSD card
  • Click the Flash button

This will flash the MicroSD card with the Amibian picture. I take advantage of a USB card reader so I can plug it in as a traditional flash drive.

Put your Raspberry Pi collectively and insert the MicroSD card. Then energy it up!

Initial setup

Next, develop the filesystem to make use of the whole MicroSD card. Click the Quit button and drop again to a command immediate.

Since you might be logged in as root, open the Raspbian config software:

raspi-config

Must-do modifications:

  • Go to the Advanced Options menu
  • Choose Expand Filesystem

Optional quality-of-life modifications

  • Set up your wi-fi community by following this guide from the Raspberry Pi Foundation
  • Enable SSH in Network Options » SSH, as that is useful for including information to your Pi utilizing an SFTP consumer corresponding to FileZilla
  • In Localization choices, change your localization and keyboard structure if wanted; the default is the UK (Great Britain)
  • Update to the most recent model, all the time an excellent factor to do

Configure the emulator

Copy the kickstart ROMs to your Raspberry Pi. If you may have a working community, you should use FileZilla or one other SFTP consumer to switch the information. (Since I am operating Amiga Forever underneath Windows, I take advantage of it copy the ROMs from my Windows machine to my Pi.) Amiga Forever additionally comes with a big choice of video games and demos. They are saved within the RP9 format, that are merely ZIP information; you possibly can extract them and replica the ADF (Amiga Disk Format) file to your Pi to play them from there.

If you might be storing the kickstart information and your video games on a USB flash drive, you possibly can configure the paths to your kickstarts from the principle configuration window.

If you bought your kickstarts from Cloanto, you could copy the rom.key file with the kickstart ROMs. They are encrypted and the important thing unlocks them and acts as your license. The ROMs will not work with out the important thing.

If your kickstarts are saved on a USB drive, you possibly can change the System ROMs folder to level to your USB. The path begins with /media/usb0 adopted by the folder on the drive the place your kickstarts are saved. So, in case you have a folder referred to as kickstarts in your flash drive, the trail can be /media/usb0/kickstarts.

Dan Wood has an incredible walkthrough video on the right way to get so far. His YouTube channel has nice content material on unique Amigas and emulation and is effectively value testing in case you are an Amiga fan.

RetroPie

In addition to the emulators talked about above, for the Raspberry Pi, I additionally suggest RetroPie, which incorporates Amiberry for the Amiga and makes it simpler as well video games. Also, FS-UAE-Arcade is a pleasant addition to any setup, because it creates a kiosk round your sport profiles, making it simpler to launch them.

To get them operating, use the UAE launcher to configure a default system in RetroPie. Then pop again to RetroPie and launch an Amiga sport. Before it hundreds, you will get a launcher display with the choice to configure settings by urgent the Enter key. Choose your profile, then all video games will use that profile to launch your video games.

Play video games

The purpose we went via all that is so we will play video games, proper? So how can we add them? I usually retailer my video games within the floppies folder on my MicroSD card, underneath amiga_files. Games are in ADF (Amiga Disk Format). Think of them as a snapshot of an Amiga diskette. Some video games require a number of disks, and there are two methods to deal with them: you possibly can load every disk underneath the “floppies” part of the emulator, or you possibly can ZIP the information and cargo the ZIP file onto the “floppy.” They will mechanically be extracted once you hit the Reset button. If you ever want so as to add a floppy mid-game, press F4 to pause the sport and return you to the emulator window. From there, you possibly can add the brand new disk underneath “floppies” and hit the Resume button.

The Amiga has a wealthy history and a really energetic group—there are nonetheless video games being made for these superb machines. Aquabyss is a brand new sport launched in 2019, and demos are nonetheless being developed.

Beyond video games

My curiosity within the Amiga goes past taking part in video games. Since the times of utilizing my A2000 to be taught programming, I have been within the working system. Here’s some locations on-line to be taught extra about this iconic system and the right way to push it additional.

I hope you may have enjoyable taking part in together with your Amiga in your Raspberry Pi! I would love to listen to your suggestions within the feedback.
