Where to (legally) acquire content to play on RetroPie

Auster

@cooliecoolster It seems Zombies Ate My Neighbours and Ghoul Patrol (Steam and GOG) come with SNES ROMs, but extracting them requires a bit of work, according to this post:
https://steamcommunity.com/app/1137970/discussions/0/3046105389665628847

Important parts of the post in case the original post can't be accessed:

Locations of ZAMN and GP's ROMs (Updated 08.18.2021)

The ROMs are located within the executable, "ZAMN_GP.exe", so the locations listed below are hexadecimal addresses. To get them, you'll need a hex editor that allows you to highlight and copy data chunks over to new files. I would recommend HxD (freeware: [url=https://mh-nexus.de/en/hxd]https://mh-nexus.de/en/hxd[/url]/ ), to complete this task.

Release build:

Steam version:
Zombies Ate My Neighbors: 1B0974C - 1C0974B
Ghoul Patrol: 19A03C0 - 1AA03BF

GOG version:
Zombies Ate My Neighbors: 1B0654C - 1C0654B
Ghoul Patrol: 199D1C0 - 1A9D1BF

1.1 Hotfix update: (Current version)

Steam version: (Thanks to Red Lettuce)
Zombies Ate My Neighbors: 1B0BD4C - 1C0BD3F
Ghoul Patrol: 19A29C0 - 1AA29BF

GOG version:
Zombies Ate My Neighbors: 1B0894C - 1C0894B
Ghoul Patrol: 199F5C0 - 1A9F5BF

The ROMs should be given the .sfc extension to maximize the number of compatible emulators. If copied over successfully, the ROMs will be 8Mb/1MB in size and be identical the verified good SNES NTSC-U dumps of both games. What this means is that they'll have the logos, licensing information, and even the secret level codes, left completely intact.

It should be possible to extract the game through command terminals such as CMD or Ubuntu's terminal, but I don't have the game to test.

If someone wants to try, just need to modify the commands from this repository to match that of the game, then do what the repository asks for each OS (adapting the steps, since it the method was made for another game):

The skip values are where the ROMs start (e.g. 1B0894C for Zombies Ate My Neighbours), but converted to bytes.
The count values are where the ROMs end (e.g. 1C0894B for ZAMN), but also converted to bytes.

Forgot to mention, but Leisure Suit Larry 7 - Love for Sail is free on IndieGala, and it appears to have the files needed for emulating it on ScummVM as well:
https://freebies.indiegala.com/leisure-suit-larry-7-love-for-sail
(it appears to have MS-DOS files too, but I can't test right now)

CoolieCoolster

@auster Added them with the link to the Steam thread to the commercial game list; thanks!

Auster

@cooliecoolster Something else:
At least the GOG version of the game The Immortal appears to be the MS-DOS version.

The store page mentions this:

This game is powered by DOSBox.

And this forum post confirms that it is just the MS-DOS version.

Can't verify if any more versions are hidden in the game files as I don't own it.

And I couldn't find any info on the Steam version as the Steam forum for the game has no mentions about the version used, and I don't own the game to check.

CoolieCoolster

@auster Ah, unfortunate then. I thought it might have been the Genesis version just by looking at it, but I guess versions can look similar. Removing that from the list I've now added everything I know about, including the buyable itch.io games, to the commercial list, so I'll finish off the remaining additions to the freeware list. If there's anything I missed though, I'll gladly add further suggestions until I decide the best way for anyone to easily add to the tables themselves, as ideally it should update the counts across the pages automatically while still being usable as a template...

Edit: And of course, if a dedicated wiki is made to compile such games, I'd be glad to help adapt the pages to include additional systems, but as the system my wiki is for only officially emulates thirteen consoles at the moment, those have been my focus for that wiki specifically. For a version of the page tailored towards a more general audience, there's certainly room to expand the article to include games for newer and/or less commonly-emulated consoles as well as computer systems such as DOS and Amiga.

@cooliecoolster About the dedicated wiki page, I created a WIP in a Wikia/Fandom page:
https://emulation.fandom.com/wiki/List_of_ROMs_that_can_be_legally_acquired
It already has some titles listed, but I was testing formatting at first. I'll be adding more titles there when I get the chance.
Should I add broader lists in the wiki too, like MS-DOS and ScummVM compatible games?

CoolieCoolster

@auster Additional lists would certainly be worthwhile, especially for ScummVM as it seems that's one of the most accessible "systems" for legal emulation. I have a few other pages on my wiki that I'm working on at the moment, but I'll see if I can help with other systems not represented by my pages afterwards. While being on a larger emulation catch-all wiki will probably help with article visibility and editor retention, at some point I'll see if I can convince the other editors of that wiki to move to Miraheze, as I'm personally not a fan of Fandom's advertising practices... Still have to finish adding the prior itch.io lists, but afterwards I'll go over these new listings to see what should be added.

Auster

"No reason for it to exist"
There goes the most obvious option.
@CoolieCoolster sorry for the ping, but what page do you suggest to use instead?

BenMcLean

@auster I'm sure you can probably open a new Fandom wiki for legal ROMs as long as you name it, "Legal ROMs" or something to that effect.

Auster

@benmclean Thanks. I'll see how that works (still newbie about Fandom's tools)

Auster

Created and already adding the pages:
https://legal-roms.fandom.com/wiki/Legal_ROMs_Wiki
If anyone wants to help, feel free to do it.

CoolieCoolster

@auster Since we're creating a new wiki, do you mind if I create it on the ad-free Miraheze instead? I'll work on making it look great in the next couple of days, plus we can import my existing table data.

Auster

@cooliecoolster Sure, go ahead!
And while the Wiki I'm working on may be a bit barebones, if you see anything good there, feel free to copy over to your wiki. The important is to give awareness to people.

And off topic, but uBlock Origin, Privacy Badger and NoScript work great on Fandom. Sure, not having to use them would be better, but at least I never get to see ads there. </off-topic>

CoolieCoolster

@auster Here, I had them create a new wiki for me: https://legalroms.miraheze.org/wiki/Main_Page. In a bit I'll work on adding the content from my wiki to the new one, but in the meantime I've enabled the MediaWiki visual editor, which should be similar to the editor Fandom has I believe. If you create an account I can give you bureaucrat permissions as well.

Auster

@cooliecoolster Thanks! I'll check it later today.

I'm definitely not any sort of Fandom loyalist. If you find another site that works better then go for it. I just said them cause I knew they were a site with free wikis

also it's probably best not to have dashes in your urls

CoolieCoolster

@benmclean I set it to legalroms.miraheze.org; simple and easy to remember with no dash. Could add a custom domain at some point, but we'll get to that when the time comes.

CoolieCoolster

@auster Finally got around to replacing the default Main Page contents: https://legalroms.miraheze.org/wiki/Main_Page. Not much for now; didn't port over any contents pages, but I tried recreating what you had on the main page of the Fandom wiki in a new format. Still needs some work, and hopefully some sort of logo at some point to replace the Miraheze one, but it's a start.
