Bubble Bobble on Retropie

Ah now I understand. This sound very good. I'll give it a try. Now everything is clear. At this point I only need an Arcade menu without any Mame anymore. I agree this is easier.

However, can you confirm there is no folder for lr-mame2010/roms. This is now an optional package and I installed it. I expected to find in Retropie folder in /home/osmc a folder like this to put roms. This is just curiosity, I understand now how Arcade option menu works.

@sasadangelo the /mame-libretro/ folder is for lr-mame2010, and all the other libretro (lr-) mame cores. it just defaults to lr-mame2003, so you'd have to change it using the runcommand.

please see https://github.com/retropie/retropie-setup/wiki/MAME (table at top)

Yes I read that doc but I still do not understand how it works. Let me explain. Under libretro I only find lr-mame2003, there is no mention for 2010 (I mean no folders).
However, even if I installed it I only see two Mame emulators in menu: one for mame4all, another for 2003. Now it's clear how to use Arcade menu to bypass all the confusing old way.
But suppose I want to understand how the old way still work today, how 2010 is still used now? I mean, suppose I want 3 menu options:

for mame4all
for mame2003
for mame2010

is this possible?

the /libretro-mame/mame2003/ subfolder is not for roms, it's just for some support files for lr-mame2003. it doesn't matter that there isn't a /libretro-mame/mame2010/ folder. both lr-mame2010 and lr-mame2003 have their roms placed in /libretro-mame directly.

However, even if I installed it I only see two Mame emulators in menu: one for mame4all, another for 2003.

in what menu?

@sasadangelo You mentioned that you understand how Arcade works. Well, the mame-libretro folder works exactly the same way. You put any roms in there that you want to launch with lr-mameXXXX and when a game launches, you press a button to invoke runcommand--just like ARCADE, and you pick which lr- emulator you want to use for that rom, for default, etc.

This concept applies broadly across many systems supported by RetroPie that can use more than one emulator. You install that optional emulator, and often there is no need for another roms folder because one already exists for that system. You simply use Runcommand to pick which of the installed emulators you want to use.
