FBA vs. MAME

@andershp said in FBA vs. MAME:
lr-fbalpha is recommended for so many roms
Can't say why, I just collected the files created in this thread.
I believe "recommended" does not mean best; as far as I know lr-fba is faster due to less precise emulation (playability focused core) while mame tries to exactly emulate the real arcade machine (may impact performance, even on a Pi3) -
@andershp Mame2003 is "lighter" compared to newer mame releases (newer=more precise emulation)
-
@udb23 But I thought "lighter" = more precise emulation..
-
@andershp more precise = more processing power needed = even Pi3 may not be able to manage (try a simple game like space invaders enabling with lr mame 2010 and mame overlay and backdrop... Too slow)
-
fbalpha is performance focused, but it's also a modern emulator. you can't really compare the performance with mame2003 -they're 14 years apart. i think most of the fbalpha code isn't even from a mame base in the first place.
so yeah, sometimes fbalpha will be faster than mame2003, sometimes not, but also it may have better accuracy in most games. mame2003 was accuracy-focused, but as of 2003. fbalpha will likely have the edge on it in most cases.
-
Allright, cool info. Now if only I could merge the spreadsheet with some rom utility to automatically choose the best rom type :)
-
When I use FBA, I put MAME roms into my FBA rom folder. Does that affect accuracy?
-
@redbatman each core (Fba in your case) requires its own romset. If got a rom that's not intended for that core you would notice as it most likely simply would not work.
No relation with accuracy. -
Ideally, it would be cool to create a DAT file for FBA and MAME2003/2010 and AdvanceMAME 3.X. I'd be more than willing to do it based on what's on my SD Card. I never did it with CLRMAME Pro. Can anyone make a suggestion how to start?
Also, where is the config to identify which games I am using MAME 2010? I know the Rampage games need 2010.

But yes, it is a project focused on playability.
@Pussyfoot Do you have the exact list of games that run at full speed on mame2003 but not on fba ?
-
@barbudreadmon No. I just moved them as I found them. The Strikers 1945 II and III games were two of them. Rampage World Tour works well in MAME, but slow in FBA.

They should run fine with the speedhack from the dipswitches.
I'll take a look at rampage world tour.
Edit : actually that's not a rom compatible with lr-fbalpha. -
@barbudreadmon It doesn't run fine with the speed hack. It runs better, but not as well as in MAME. Also, the speed hack affects other games, yes?
-
Konami 4p games has slowdowns on latest fba. More noticable on a pi2 at 1ghz. They're fine in fba 2012. Not sure if this is due to being more accurate or a bug.
-
@pussyfoot @Darksavior All of them run at full speed on my rpi3 @1.3Ghz.
Yes, i suppose if you have older/slower hardware, it is better to use older software.
-
@udb23 Well it does. Most of every game I use for FBA are MAME and they work jusr fine. Of course they are mostly fighting games

ROMS in the end are just different versions of dumps of the actual real game ROMS.
-
@udb23 Huh, did not know that. Thanks
-
Just tried getting the newest FBA version of Gyruss and replacing the rom file with this. Strangely it still booted with MAME2003 as the default emulator and worked. Should this be possible? Couldn't tell any difference though...
-
@andershp said in FBA vs. MAME:

Yes, various older ("classic") arcade ROM dumps have not changed over the years. So even being part of different ROM sets the actual files contained in the zip are the same.
Same happened to me with Space Invaders if I remember well: working with multiple cores.
If there is any improvement on these games with newer versions of the cores is on the emulation (code) side.
