Rom file types

raspberry79

@dankcushions
I open the rom folders one at a time and right-click to see what type it is. Sometimes i can click into the rom folder and right-click on properties and it will show the type of file
game r.PNG

@raspberry79 so with that specific example as there’s only one system that supports .a26 in retropie, so you put it in the folder for that and it should work. but doing the whole lot in this way seems very tedious. i would give up with this collection/approach

Better find another source for roms that have everything categorize by system.

@windg
When going over to download the rom, it will tell the name of the console. So i would write down the name of the game and the name of the console and then place the rom in that rom folder with the console name like snes, atari and more.

Yeah. That's how we all do it.

You can always try with my first scraper:

https://github.com/zayamatias/sscraper

It has a sort option that will get the checksums for the file and sort everything under one directory (look for --sort), rom names do not matter at all, to be honest, checksums are much more reliable.

It is not the most user-friendly scraper, but I'm working on a new one (https://github.com/zayamatias/retroscraper) that should be user-friendlier.

Cheers.

On here https://retropie.org.uk/docs/Supported-Systems/ does the extension matters to the roms.

kiro

@raspberry79 for the emulator it does, indeed, bit not anything that's before the extension.

I downloaded a Rom and once download i open the zip file and it said file type MDF and MDS what is that type and what console it go in.
I also downloaded one and found out it was a rar file type

kiro

@raspberry79 As a test, give me the SHA1 + MD5 (preferably the unzipped file) Windows just any tool such as https://www.nirsoft.net/utils/hash_my_files.html) for linux just run sha1sum and md5sum and post them here... with those, unless they are very obscure roms, I should be able to tell you the correct filename and the system they belong to... thanks!

Btw, .mdf is a cd imaging extension, this could be PSX,PS2 or even Saturn, .mds, never seen it before...I see just one rom in my DB with .mds extension "299 Panzer Dragoon 2 Zwei (U).mds", a Saturn game, probably won't run in any emulator supported by retropie.

I made a snapshop here maybe be a little easier to to explain.
https://retropie.org.uk/docs/Supported-Systems/#

I just drop my roms into the system/console instead and not worrying about the extension
So, I just need to know the console name of the rom

I see rom that is .A26 ant that <Atari2600>

@raspberry79 ok, if what you need is a complete list of extensions supported by each emulator supported by retropie, see it here: https://raw.githubusercontent.com/RetroPie/RetroPie-Setup/master/platforms.cfg (thanks @mitu for the link) ... sorry I just saw you also have a similar link. I'm a little bit confused :-)

@kiro
i added a link above the snapshot https://retropie.org.uk/docs/Supported-Systems/#
Apparently, I have to use .7z to extract all the roms
Some were downloaded in rar file type and other weird types. I can extract the rar rom to a26 .7z to BIN

Pi4 Retropie 4.8

I tried playing a game, but it keeps popping up a message saying errors are logged to /dev/shm/runcommand.log

It must mean i have to roms in the wrong folders or the emulates isn't installed on the retropie or what

kiro

@raspberry79 It can mean a lot of things, is it possible to have a view of that /dev/shm/runcommand.log??

raspberry79

@kiro
Is it that ir-stella2014 isn't installed on the retropie

it just when i lunch into a game that error message popup /dev/shm/runcommand.log
Ir-stella2014
That here is a game launching problem here. trying o launch a rom game and that when i get that error

dankcushions

@raspberry79 it is installed. that’s not an error message. it’s saying “i’m launching this game on this emulator” - if the emulator wasn’t installed you wouldn’t get this far.

post the log as per instructions in https://retropie.org.uk/forum/topic/3/read-this-first

raspberry79

@dankcushions
So, i can't play the game, just getting an error if the emulator like lr-stella2014 isn't install yet.
Now' i'm installing them one by one. but when i had created the rom folders on a usb drive, i copy the rom folders over to the laptop so i can see what emulator is install and go to the one that haven't got a folder for.
I can look at the rom folder to see if i got them, if i get the rom folder bypass that and go to the next emulator on the list and install it on the retropie.

kiro

@raspberry79 please, post the contents of your log file...any other "trying to guess what's wrong" will not solve your problem.

dankcushions

@raspberry79 the log file is generated on failure and success. please read the link and follow the instructions. the message you have posted proves the emulator IS installed, as i said. that message appears by default regardless of whether the game launches successfully or not.
