See you, cynicfm. But perhaps I have a direct answer about your question regarding Amiga-emulator and emulators in general: Link

Some of them need a proprietary firmware to run. The reasoning behind the developers removed Vice from the repositories as the C64-emulator is semifree. Code is free, but for execution you'll need another bunch of firmware-blobs. And I think it is the same with Amiga-emulation, but therefore the question: What did you two use? Was it fs-uae from the AUR? Regarding this I'd recommend to build your own portable version for the emulator, if there is need for proprietary firmware-blobs. So you are in control in your HOME-directory when installing something new. But that's a good hint: Yes, of course you can also share console-classics if you execute some. But have in mind that you should own the cartridges. I'm using therefore the Retrode to archive my older cartdriges for the SNES, Sega Genesis or the Sega Master System (Link).

Regarding Wine: You can use your own so-called prefix. These are own packaged folders with everything needed for a further execution or you can use of course the default prefix called .wine. If you want I can give you more insights later on regarding the technique behind and how to use this for saving and really preserving your classics for reuse everytime you want. That's an absolute benefit with Wine, also have look for the prefix-concept here. Good night and have a good sleep!

EDIT: Ah and because of Minetest I've also to tell some stories. But better tomorrow to share some first pictures here.

Emperor - Battle for Dune using Wine!

Just as an addition: About Emulators
It's a pity but really many emulators are non-free or just semifree. Therefore I have to look after alternatives and I think I have found with mednafen one good in the repositories for SNES, Master System and Genesis!

First things first: Yes, those pictures from Minetest are just my own, taken last evening. I can share the world-data with everything included, if somebody is interested - but therefore also a warning: Bunch of modifications added as my nephew started with this world along about four years ago with his first tryouts on GNU/Linux and he is playing until today, building also. I can also share newer creations more focussed about farming and integration for other modifications in Minetest 5.0. The world-data for version 0.4.15 is about 800 MB, with all modifications.
And there is much more regarding Wine, ScummVM and DOSBox for example.

Regarding the older titles: There are bunch of possibilities outside Steam or GOG. Perhaps the initial question: What game exactly? I would therefore trying a search using ebay - warning therefore: this has also a price and you should keep in mind that ebay is also collecting data. I think it is better to try searching for original disks instead of downloading the data. The problem besides legal issues: You never know if the data is corrupted or modified. Some websites offer you games from the DOS-era but cut out FMV-sequences, music or further sounds. And as those games rely on everything creating atmosphere it is not helpful having a silent "Monkey Island" for example.

Another idea would be searching in local stores near you - if there are some offering cartridges or boxed versions. Our times are changing and even within hard- and software this is clear to recognize. When using my X200 with Libreboot some people look at me as I have taken away one item from the museum and it is also about sweet bitterness: As I've said back in 2004 to friends that I have qualms regarding the upcoming trend for using more and more of Steam most of them laughed at me. Today it is even more bad than I've ever thought it could get as digital distributions are the defacto standard and people see the normal installation and setup of a title as senseless. And this is just the top as younger generations doesn't even know about older things coming up from the DOS-era, the needed things to know regarding computing in general. It's just some wording called "retro".
In the end I have another problem with the thing called "copyright": The wording is clear as All rights reserved. is just nothing more than you as shorttime user - in these days fitting more than ever before. I'm in favorite for copyleft as the licensing is clear what is allowed and what exactly not. And sharing is also part of preserving as I have also the version of Minetest 0.4.15 up and running here. The reasoning behind proprietary, older titles are just the memories and the perservation of knowledge as some of those titles are artistic masterpieces.

What I will never understand is the fact that some users of Linux-distributions cheer up when something within the cosmos of Steam happens and they think the freedom was widened when Steam was available in 2013 for the Linux-platform. Nothing was widened since then. Just another bunch of proprietary waste was released and many titles with proprietary middleware flooded onto Linux, with false promises.

Well last game i played on hyperbola is the Might and Magic VII: For Blood and Honor GOG version, but i downloaded it from torrents... Not sure if i should state that publicly . I don't want to be a pirate but this game as well as heroes of mignt and magic III is something i can't buy in a shop, and not really keen on buying digital versions from corporate steam or gog, if i can have the same from torrents... Why would i want to give my money to billionaire corporations... Is it really wrong to download one game or two from torrents instead....

this mario looks so cool... Do you have to download games for mednaffe from some website??

Well, the sad fact is that i have read somewhere on internet once, that company cdprojekt that is behind gog.com made it's first chunk of cash by unauthorized copying of games in 90s...
It's a bit selfish to say things like 'my money'. Reality is i don't even have money to buy anything from gog.com especially games from my youth like mm7 or heroes 3... And also even if i had genuine copy of mm7, i know that there are some issues with it on wine or newer windows systems than xp with playing background music... gog made the audio playable somehow.
But i really want to complete this game before i delete it as it is from torrents, but please tell me if in your opinion i should delete it now and try to get genuine copy in the future or keep it on pc and complete it first

Well i have read on the web that owned of cd-projekt, shortly after fall of communism, when poland transformed into capitalism in 90s, he was cracking, copying and then selling games from western countries to people in Warsaw... I have also read that it wasn't illegal to do this at the time, because there was no law that made it forbidden to use...
It is a bit off topic as well... I am really paranoid about playing a game from torrents, although mm7 has some really cool music in the game, bracada desert, erathia, or titan fortress is something really cool... Sadly getting this game from torrents was the only option for me... ;/

Well i didn't want to post picture of this in this thread because it's from torrents like i said...

Yeah i have played wesnoth before ;P
it relies on dbus though

Yeah, but it is time for rebuilding those packages enforcing bloatware.

Managing the usage of makepkg is not that complicated at all. Yes, the first entry can be full with risks, but in the end it is very interesting getting a deeper look into free software.

Could you give more insights about the new user you've created? Try the following:

groups <USERNAME>

And you should include following groups at minimum for the user you've created:

sys
video
audio
optical
storage
users

You can reach this with the execution of the following command (sudo is needed therefore):

sudo usermod -aG <GROUPNAME> <USERNAME>
