@jlopezvl Having latest mame on your rpi is nice and all, but what about performances ? What are the systems playable full speed ? Especially, what are the systems that weren't playable full speed previously with latest romsets through fbalpha ? What about support for features involving savestates (netplay, rewind, input read ahead, ...) in latest mame ?
Sorry, I have tested only a few games and i cannot answer you about speeds and compares ... Only note that this compile is for lr-mame (libreto) and in my test (five-ten games) speeds was 100% with no frame skip ... But i have not time yet to test other games ... Games tested was "tokio scramble formation" , battle garega, metal slug ....
Some months ago i compile mame for linux (not libreto) and speed was slow in this games ... But with libretro speeds are good compare to mame without libretro that i tried some months ago (was mame .199)Now im compiling v206 and after this i will do more test with different systems and roms ...

All games already playable with latest romsets through fbalpha. What about input lag and the features i mentioned ? If input lag is higher and/or you can't use those features in mame, i don't see the point of using mame over fbalpha to play those games, with read ahead all those games are playable at 0 input lag with fbalpha, and it's already at roof level without it. It is just my (probably biased) opinion though.

My only desire was to compile lr-mame, not to compare with great fbalpha ….. Im not a game tester but i trust you opinión ….

Also I havent the answer to your lag question … Maybe if you can test it and answer me ..

Apparently lr-mame is 1 frame behing standalone mame for input lag, while lr-fbalpha is the same as standalone fbalpha. Otherwise the 2 standalone emulators generally have the same input lag for a game, which means lr-mame must be 1 frame behing lr-fbalpha on average. Savestate support is partial in mame, while all games in fbalpha have savestate support to my knowledge, furthermore savestates in fbalpha were optimized for the libretro features i mentioned.
To sum it up, fbalpha is better integrated with libretro than latest mame, so it gives a lead in terms of features, it's also lighter in memory and overall faster. I wouldn't recommend using lr-mame for a game supported by either lr-fbalpha or lr-mame2003-plus (which has the best libretro integration of all the mame cores). -

Only its for have more chances to run games ....

My experience in trying .206 wasn't positive. It was crashing when loading any game until I deleted my retroarch.cfg and auto generated a new one. I enabled threaded video since it was off by default from this newly generated cfg. Metal Slug 5 ~50fps. Battle Garegga ~50fps as well. Any cps1 or cps2 game freezes the pi with a "loading machine 99%" or similar screen. I really wanted something that could run system32 games properly and fullspeed. ~20fps in spiderman. Mame2003/plus is fullspeed but it has those shadow graphic bugs.
Pi3b+ at 1450mhz. -

Pi3b+ at 1450mhz.Its Good to know it … Because of it also its avaiable fbalpha … I only compile lrmame to test it ...

@Darksavior That's more or less the results i expected in terms of performance for lr-mame on a rpi3.
Sadly, sega system 32 is not available in fbalpha, but maybe someday.
