Since this thread evolved into exactly what I knew it would, I will just say that after spending a
tremendous amount of time with the original FBA-XXX and Pro derivatives for so long, it is painfully obvious that FBL blows both away. The emulation is more accurate, the GUI is an amazing leap forward, the built-in cheat database for
all games is marvelous, the entire emulator itself is
much more stable, the HDtv support with filters is dramatically improved, I could go on and on.....and on.
My personal friends can attest that I literally grew up in arcades -- that's where the stork dropped me off.

These games are my legacy and I'm very aware of what should be what with the games FBL supports especially. Compared to the other emulators I have on my xbox, I can clearly tell that the games in FBL have superior emulation compared to any previous versions of FBA. FBL makes all of the older versions obsolete in my personal opinion, solely on how it runs the games. At the end of the day, the games are why I'm even interested in these emulators at all, CoinOps included. If a new version wasn't up to snuff in this area, I would most definitely say so regardless of who's working on the project.
As far as Mame on the Xbox is concerned, it's MAME on the Xbox. Final Burn is Final Burn. For as long as any kind of FBA exists on the XBOX, I will be using it to run CPS1, CPS2, Neogeo, Sega, Psikyo, Cave, and Toaplan based games. Nothing else can run those games as well.
One example someone could use against FBL is the slowdown in ESPrade. Like Metal Slug 2, that slight slowdown is
accurate to the arcade version, which FBL is more faithful to. But unfortunately the slowdown and stuttering in CoinOps for many CPS2 games isn't accurate
or faithful to the arcade hardware. There are more cases than that where it's better to use FBL. The R3 version of CoinOps (my personal fav version of MAME due to its HD support) is worth having around for the games that FBL doesn't support. R3 Showcase ended with a bang in my opinion. It was a good stopping point for CoinOps, as Night Slashers and Osman were added for those who really wanted to see them added.
FBL clearly is the best version of FBA on the Xbox (and best Xbox emulator period in my honest opinion). FBA-XXX Pro was my fav before, but FBL takes it to another level starting from it's core. The emulator core is updated, the drivers are updated, the romsets are no longer ancient, the HDtv support has been updated, the GUI is updated -- I just call it the way I see it. FBL's just got a lot going for it with such a polished first release. The talented people behind it bodes well for it's future and the Xbox scene in general.
It comes down to personal preference. We aren't going to have one emulator that does everything better than the apps which are dedicated to handling more specific tasks. We also aren't going to have an FBA on the Xbox that runs all of MAME's games. That was never the point.
Unfortunately, this topic was flamebait from the very first message and it has followed it's natural progression. Stuff like this is why I have so few posts in 3+ yrs here. I see no lack of appreciation for either emulator; and it really isn't even a comparison with a leveled playing field in the first place.
In summation, I think most users can truly appreciate both apps. So this dispute is useless. I hope the thread starter can find the answers he seeks through all of the garbage in his way. Now if only we could get this thread closed.
