@lamaman1971 Aside from MAME2003+, MAME cores have a very shallow libretro implementation preventing some stuff from working properly, which is why it's recommended to prefer MAME2003+ or FBNeo with the appropriate romsets if the game you are trying to play is supported.
You might be able to force the values you want by directly editing MAME config files, but i wouldn't be able to help with the details, and i don't recommend asking the MAME team for help about this.
Hi we wrote a complete guide on how to setup both a spinner and a trackball at the same time, so that the configurations are persistent and will apply to a whole game folder.
The idea is to set up a default retroarch config for mame/fbneo that will configure one of these devices as the default mouse (for example, the trackball), and create then just a file for rom folders that will be spinner specific.
For example, you have a roms/mame folder -> all games in there will work with the trackball by default, thanks to the global default config. Then you have roms/mame/spinner then for this folder, you will have to generate a retroarch "content configuration file" that will apply just for this folder, and set the mouse_index to the one of the spinner.
Trap: the retroarch menu will not let you save mouse_index configs, but will create the config files. You will have to add manually a line with player1_mouse_index = 2 for example...
We wrote a detailed guide (in french, use deepl.com to translate) with screenshots, etc. And we use it on several Retropie arcade cabinet that we built, that have both trackball and spinner in the control panel.
I 'solved' it by adjusting the controls in the RGUI. I just remapped the option of test menu to a coin insert since I can't remap it to another key. Not a real solution but for me in this case an acceptable workaround.
@lupin it may well be a generic thing that would affect the official retropie image also but they are not supported here because we don't know what has changed under the hood, and also do not want to encourage the distribution of illegal material under the retropie name, etc. the image maker calling it 'official' is particularly egregious...
also have complete set of both Mame2010 and Mame2016. I don't want to keep both romset on my HDD and waste a lot of storage space for nothing. Could anyone suggest which romset should I keep for future use?
Keeping on-point, when possible, 2016 should trump 2010. For one thing, you could 7zip 2016 ROMsets and they'll work nicely. If you have any questions about compatibility, refer to my Arcade Recommendations List. You'll note that lr-fbneo is highly recommended, but you'll also note 2016 vs. 2010 compatibility for other ROMsets.
Hope this information is useful. It is also highly optimized, in case you just don't want multiple variations of some of your games. Or don't care about the 300+ Mahjong games, or gambling/casino games.
Interesting, and I never use the controllers in bluetooth mood, they are always hard wired to the console with USBC
Never tried overclocking, just use it stock for the most part.
More interested in the best em ups anyways, but Jurassic Park was always a fav.
The Sega system 32 graphical rewrite circa MAME97-98 will always cause performance issues on lesser devices,
as @barbudreadmon suggested quite often this can cause skipping and or other sound issues. MAME2003
is one of the fastest cores and apart from that it uses the faster although slightly more imperfect system 32
video code from before the big rewrite i mentioned above.
So it might be your best bet to get the best performance on your device of choice and may sort your sound problems
when playing Jurassic Park it's worth a try at least.
I'll stick with a permanent preference for the PS2 version.
It's a game from 2000, yet the Graphics are The Tip of Everest!
Too bad PS2 Emulation is a train-wreck that's yet to be cleared up.
