What is the best MAME to use with Pi 4 4GB? (Largest library, highest compatability)

obrie572

@roslof Given your notes on the poor performance of mame 0.223 and above on RPi4, what is your suggestion on which emulator to use instead of lr-mame? Have you been manually compiling lr-mame 0.222 or do you have an archive of the 0.222 binary?

I'm setting up a new install and the binary that's installed for lr-mame is 0.229, so I'm trying to understand whether to work on building the 0.222 binary, finding someone who has hosted the old binary somewhere, trying out the 0.229 binary, or replacing your lr-mame recommendations with a different emulator.

Thanks and appreciate all your hard work!

Good question.

First thing, here is the release for 0.222. Suspect we can tweak the MAME script and build a new executable.

The only reason I'm recommending it, is because lr-mame is arguably the best at rendering vector games, but the Pi4B can't handle MAME's new discreet sound engine for many games that may have previously used samples. This was introduced in MAME 0.223. Performance is simply too demanding.

Another, easier option is to try mame2016 or even AdvMAME (which I try to avoid) which both can handle the vector games.

@roslof Thanks, that's so helpful! I've now finally been able to put together all my arcade games in a single folder and they all run great. Some of them (such as alien 3) are much improved thanks to your recommendations.

One minor thing I thought I might mention in case others run into the same issue - for me at least, the mappings for emulators.cfg to 'lr-mame-2003-Plus', didn't work until I changed them to lr-mame-2003-plus . My system didn't recognise the system with the upper case P for some reason.

Thank you for the kind words.
You're absolutely right. The "p" should be lowercase. I've fixed this throughout the doc. Appreciated!

@roslof Thanks a lot! Is there any automated way to generate the romset with the correct rom versions for each emulator in the list?, something like a .dat file for clrmamepro or some bat files that pick the roms from each emulator's romset?

I'm not aware of any easy way to do that. Each emulator has its own matching romset. Could sort the list by emulator and copy relevant roms one set at a time into a folder. Probably starting with fbneo, since it's most recommended. Run clrmamepro against that set, then move to the pi when complete. Repeat with next sets, isolating each set as you go, then transferring to the pi.

@roslof Thanks for tips! I recompiled MAME 0.222 by tweaking the build script and it worked perfectly with your compatibility script.

One thing I noticed is that your spreadsheet lists lr-fbneo for "offroad", but so far as I can tell offroad is not implemented by fbneo yet. Any chance that should be lr-mame2016 or did I miss something in the dat file? (Let me know if you'd prefer to address those questions in a different thread)

Correct. It should be lr-mame2016. I made the change in the doc. Thank you!

Also, I have no trouble if issues are called out here, but you may also "Comment" in the doc. I review them ever-so-often.

@obrie572 May I ask which changes you did to the script? Thanks!

Edit: I just replaced the sources_lr-mame() funtion in lr-mame.sh as shown below and it worked

function sources_lr-mame() {
    downloadAndExtract "https://github.com/libretro/mame/archive/refs/tags/lrmame0222.tar.gz" "$md_build" --strip-components 1
}

#function sources_lr-mame() {
#    gitPullOrClone
#}

Well, maybe I was simply hoping it would have been supported by fbneo, but I hoped a bit too hard. :P

@roslof Where you are using 'advmame', which version are you using? 0.94, 1.4 or 3?

@roslof First of all, thank you so much for the list! I've been looking so long for an awesome list like this!
My question is, is there a way I could filter a set with your list? I'm a noob when it comes to scripting and filtering lists so any help would be wonderful.
Thanks again!

AdvMAME 3. And sorry for the delay. Missed this post.

Cheers. Not 100% what you're going for, but since my list is read-only, simply make a copy of it for yourself. Then you can use the filters from Google Sheets (already present in row 1) to sort/filter however you wish.

If you filter by Recommended Emulator, you can get a few good lists together for fbneo, lr-mame, etc... and download accordingly -- or cherry pick as needed. Still, it's a quite bit of manual work though.

What you could do is generate a .dat file against your own romsets that you have based the list on. That would be 'roslofs' .dat file. If you provided that then others could rebuild romsets to match if they wanted. Obviously they would need to make sure they used the same emulators - so would reference your emulators.cfg

Is there a tool that can generate the file based on scanning current folders?
A manual creation would involve a whole lot of copy / paste.

barbudreadmon

@YFZdude i think clrmamepro has a feature like this

Floob

Yep - its called dir2dat in clrmamepro
