I understand what you mean iq_132...But it's not because the Mame Team seems not to have interest for thoses sets that's thoses sets are not interesting 
another thing...It's interesting to see that FBA doesn't always folllow Mame ROMset (i think about decrypted neogeo sets and Phoenix Editions Sets...and last Three Of Wonders Bootleg added by Barry o FBA). In my opinion, FBA could make the difference with Mame, not by the number of sets ported, but by the quality of sets added and the emulation acuracy (sorry for my bad english).
Of course i don't talk about competition...But (and it's true) some improvments from FBA has been added to Mame, no?
PS : sorry to spam this thread and for my post "off topic"
Don't worry about posting here, as far as I can see you're on-topic, you recommended some drivers to be ported, and this is just a follow up to that post ^^, so at least for me it's ok.
MAME development is ruled by some strict lines, I mean if you're gonna make a driver donation to MAME or some feature, it must follow a series of requisites,..and you see, FB Alpha is a humble project, coming from a humble emulator "FinalBurn". FBA does have some rules and requisites before doing a driver contribution, but as I can understand, FBA will not limit most of the drivers contributions.
For example, let imagine someday I come up with a Vasara I / II drivers including the required CPUs ported for FBA, but FBA is not currently a emulator supporting that kind of hardware, or with no current objectives in emulating it. I think the most probable action by FBA Team is implementing that contribution. For example look at Genesis emulation on FBA!, MAME as far as I know doesn't have Genesis drivers in it's core, MAME could have them easily added but they just don't do it. They can easily emulate MASSIVE amounts of other systems / consoles, but they don't do it because of their objectives and development rules (btw, the name itself, limits them, M.ultiple
A.rcade M.achine E.mulator, oh and yeah there are other ports of MAME supporting consoles but that's another story
).
If you ask me what emulator do I use in a constant basis, my answer would be FBA. Not because I'm a fan and contributor, but because it have what I'm looking from a emulator, and it have what I like ^^. I use MAME like 1 time per 4 months , because sometimes I wanna play some games not currently in FBA, just a few. But if they were on FBA I wouldn't be using MAME at all
. At least that's my reality
So, finally, to get to the point xDD ( I think I did go off-topic LOL)... I think FBA is doing good by emulation some romsets not currently in MAME, like the "Street Fighter Zero (951020 CPS Changer)", it's very nice to see some rare romsets emulated. I dont like the idea of having lots of bootlegs / hacks in the emulator btw, I just would like to see rare romsets. Because after all it's not just emulation, it's
preservation of arcade games.
So that's my opinion, on the recommendations made by JacKc ^^. I see FBA like a very different emulator from MAME, because is like a free soul, doing the maximum it can do! pushing it's limits! and evolving from time to time following it's own rules!
SeeYaa!
