MAME roms not all working
-
I have been wanting to play different mame games for the past couple of days. none of which worked. I tried different emulators but dont work. retropie software detects the zip files but wont play them. what can i do?

You'll need to locate your own ROMs but once you have them here's a tutorial on how to manage them:
https://github.com/RetroPie/RetroPie-Setup/wiki/Managing-ROMs
Here's how to use MAME on RetroPie and the ROM locations:
https://github.com/RetroPie/RetroPie-Setup/wiki/MAME
Some of the sections have additional links you'll need to drill down into that give more details and steps in tweaking some of the MAME settings.

@Riverstorm sorry but this did not work. Is there another way to repair the roms so that they can be read correctly?
-
getting mame roms to work is trail and error. People always reference
https://github.com/RetroPie/RetroPie-Setup/wiki/Managing-ROMs but it doesn't always work. Which game are you trying to add maybe I can help. -

I don't think it's trial and error as much as following the tutorial. If you have the correct ROMs the DATs will organize them precisely in to the correct zip file regardless of what set type is used like non-merged, merged or split. It will also correct the name and verify the CRC. The ROM management tools work very well and the DATs guarantee your set will work in the emulator you're building it for.
That doesn't mean every game is working as some are bad dump or no dump ROMs in which case the game just doesn't work for example Xenophobe doesn't work in lr-imame4all or lr-mame2003 but works fine in AdvMAME.
The only other method I can think of is very time intensive which is to look at the DAT and add them by hand to the proper zip. Keeping in mind you'll need to be aware of the CRC on each ROM file as the name could be correct but the CRC incorrect. You could also have a correct CRC but named incorrectly. There are several scenarios where issues may arise but the ROM management tools will organize and do all this for you automatically if you have the correct ROMs before you start processing them.

@megatron99 dungeons and dragons, and street fighter 3 or alpha

@Riverstorm so lets say I just want one game... could i use the method in the tutorial to try and make it work?

Yes it would work but you'll see thousands of errors for the missing ROMs but it would work fine with no issues.
If you're only looking for a few games you'll find many sites that allow the downloading of single game ROMs for the specific version you need.
Look here for the ROM set version you're looking for. At the top of the page is a table. Look under the Emulator & Romset columns for the version of MAME ROMs to match the emulator you're wanting to use. Several search engines will produce the results you're looking for. As per the forum rules and to avoid any legalities you can't post direct links but the information is available in many locations.
It may seem daunting at first but give it a go and once you get rolling with it you'll find it a snap to do.

It should be said here on this thread that getting MAME ROMs to work isn't actually trial and error at all. Sure, there are a few ROMs that fail in MAME on the Pi, sometimes merely due to performance, but by and large, MAME should be able to launch ROMs from the right ROMset. The key is knowing how MAME ROMs are built, and getting a known good (complete) ROMset of a version that matches the MAME you plan to use to launch it. It also requires an understanding of parent-child ROMs if you are expecting to launch clones. This isn't guesswork. It should be easy, provided you know what you need and you are able to obtain it.
I think where it feels like trial and error are situations when you don't pay attention to what you need, or you try to launch MAME using a ROM from one set while that version of MAME requires a different set. Sometimes that works (because an individual ROM may not have changed between versions). Taking chances like that is fine, but claiming that none of your ROMs work when you may not even have the right versions is the wrong way to go about it, and you can't expect a lot of sympathy in the forums. Figure out what ROMset you need and make sure your ROM is from that set and that it does not require any parent ROMs. It's never hit or miss. There is a proper way to do it.

Well said, I agree when I first read the post about trial and error I bristled a bit. :) When using the DAT with a ROM management tool it's really an exact science.

what would the rom set of dungeons and dragons as well as mega man 2: power fighters be?
-
@Parzival first you tell me, what version of mame are you going to use to open these?
-
Because you need both bits of info to answer your question. The ROMset must match the MAME version you plan to use. Otherwise, it may not work.
-
@caver01 mame4all or mame2003 :)

@Parzival Ok, so you need to go find two ROMsets. 0.37b5 for mame4all and 0.78 for lr-mame2003. Let's look for Mega Man 2.
Checking here, you can look at the compatibility lists. I looked at 0.78 and someone has tried MegaMan2 and reported that it does not work on the Pi3. No notes added. That's unfortunate. if it did work, though, 0.78 would be the ROM for that emulator. Next, I checked 0.37b5, but Mega Man 2 is not in there. It's from 1996, right? So perhaps this ROMset is simply too old have a game that was so recent (by the standards back then).
So, I looked at AdvanceMAME 1.4 which is a fallback for me. It's more recent at ROMset 0.106, and lo and behold--there it is in the compatibility list and someone has said it works on a Pi2. That's good because it probably works even better on a Pi3.
So, the short answer for MegaMan2 is that you can run it with AdvanceMAME 1.4, which means you need to find a 0.106 ROMset.
I know this sounds like a lot of rig-a-ma-role to get a single game to work, but that's why we have more than one MAME emulator available. The point is that each MAME uses a ROMset that matches. You can't just download a random zip file from somewhere and expect it to run on your preferred emulator.
You will have to do the same investigation for your D&D title. Newer arcade games are going to be harder. Classics from the 80's often give you more choices.

That's well written Caver a great way to explain some of the reasoning on multiple emulators and ROM sets.
-
thanks guys you are the best! Mega Man is working and ready to play. Ill be posting pictures and videos of how my cabinet looks ;)
Thanks Again! -
I got D&D and Alpha to work on FBA
-
D&D and all three of the street fighter alpha games wont work using mame4all or mame 2003. Use final burn alpha for these.
