Don't feel too bad. I started this journey just before Christmas. There is a lot to take in, I'm learning new things every day, and I still don't know much.

The one piece of advice I will offer you is this - Don't skim the wiki articles. Read that ish. Then, re-read that ish. Then, re-re-read it and look for other write ups about it. By doing so you will learn enough to be able to ask the right questions and that, my friend, is the key.

Nevermind the questions, I just realized I've been reading versions #s wrong.
I literally was getting .37 and .138 confused, the later being more up to date from what I can tell?

@Jiryn 0.138 more up to date, but not going to work on any mame emulators in retropie.

Jiryn

@dankcushions
Yea, I realized I was totally overlooking the fact one had a 1 and one didn't...
Now I feel even more stupid.

Lr-2010 seems to be able to run .139, but someone above said it's not as good?

@dankcushions
Thanks

Ugh, feels like every time I make a step forward.. I get pushed back a couple feet...
So, I finally found sets which should work..... but they are in .7Z format.

I know there are conversion tools, but will there be a loss of data between the conversion, and are there mass conversion tools, which will change an entire directly instead of one at a time...

Other than that, looks like I am ALMOST there.

@Jiryn http://www.bitser.org/7z-file-converter-how-to.shtm or just get a .zip set.

Jiryn

@columboscoat
As I said, one step forward.. two steps back!!!
I grabbed that, doesn't seem to be able to do conversions in mass (or I am missing something) worried about loss and corruption of data.

I'll get this..
Thank you for all your links, help and advice..
And yes I know I am thanking you all too much, but it means a lot to me.

columboscoat

@Jiryn What ROM set version did you get?

Jiryn

@columboscoat
Found Set of .138 through .171 along with other consoles
All the files contained are .zr though.

Looking for .ZIP alternatives

columboscoat

@Jiryn have you actually read this? https://github.com/retropie/retropie-setup/wiki/MAME None of those sets will run on the emulators on the Pi. Do yourself a huge favour and get the 0.78 ROM set. This works with lr-mame2003 on RetroPie. It's literally the most fool-proof way to get MAME running. 0.78 is a non-merged set. The ROMs are (pretty much) stand-alone. I have installed 100 games that way. And they run flawlessly on lr-mame2003 because they are from the "0.78 MAME ROM REFERENCE SET".

Jiryn

@columboscoat
Yes, I've read it!
You asked what I had found though and was being bluntly honest.
I know I need the .78 to run with Lf-Mame2003... but I had also found complete sets for other systems, which I didn't want to name individually.
The problem was, they were 7Z files, which I am now batch converting into zip files.

I'm still having trouble tracking the .78, since most seem to be .1## something, nor will I ask from them.

As frustrated as I am/was I am also enjoying this as a learning experience!

columboscoat

@Jiryn I understand it can be frustrating. I am actually only trying to help. There is ZERO point in you downloading a huge ROM set that will not work on the Pi. You may have read it but did you actually understand what it was telling you?

Jiryn

@columboscoat
I downloaded one of the other consoles romset that I was interested in, and found the 7Z problem.

As I said above, I at first didn't notice the .1 in the #s, I was trying my best to only match the last two digits like a moron and have since fixed the problem/way of thinking!

I am laughing at this, this entire thing has been a frustrating learning experience. (Yea, I know I act like a total moron at times.)

columboscoat

@Jiryn I'm sorry but I'm out. You are asking for guidance and help and ignoring it when it is given. I'll say nothing personal, except I will no longer be responding to you. I genuinely hope you figure it out. Good luck.

Jiryn

@columboscoat
I understand what you're saying, and I am looking for a compatible .ZIP Romset in the right form series for MAME.
That was the main discussion for the topic.

The 7Z was related to a different console, and I was able to batch convert them from 7Z to zip, and they are working fine.

I thank you for your assistance here, I wasn't trying to sound belligerent.

I'm sorry for the confusion, I was working on two different topics at the same time in the same post.

Jiryn

I think I have quite a better handle on this..
Thank you to everyone, it was a trial and error learning experience and you all helped out.

I apologize for today's questions, they were quick bouts of confusion which was quickly cleared up through research in experimentation, but I realize my replies only made it sound more confusing than it actually was.

ANyways, I'm closing the topic now.
Thank you to @columboscoat @dankcushions @batesman @markwkidd @mrbwa1 @rbaker

@administrators @Global-Moderators Would an admin or moderator mind purging this topic, it seems quite a bit superfluous at this point.

It's also sometimes referred to as the "MAME 2003 Reference Set". Download it, then drop the ROMs into /home/pi/RetroPie/roms/mame-libretro/ and you'll be good to go.

Jiryn

@mediamogul
Yep, starting to notice that as well.
When I said I found Rom Sets "Other Systems" I meant the other systems beyond MAME supported by RetroPi.

So I wanted to see if the sets would work, and found the files to be all 7Z. Though I was able to convert the 7Z files and they work just fine now.
