This emulator is FBA. It's not MAME. When people say it uses MAME 0.149 romset, it means that you can take all the FBA romset  from the MAME romset. But that does not mean that the entire MAME romset will be supported by FBA.

FBA supports 3159 roms. MAME 0.149 supports more than 20000 roms. Many roms are not on the list, simply because FBA does not support them.

Thank you.

Yes, while Irem M62/M63/M75/M77 run ok (60fps), M72/M81/M82/M84/M90/M92/M97/M107 run too slow (about 5fps).

I've done a little research http://www.system16.com/museum.php?id=4 and noticed that M62/M63/M75/M77 all use a Z80 as main CPU, while M72/M81/M82/M84/M90/M92/M97/M107 all use a V30 as main CPU (M92/M107 also use a V33 secondary? CPU). All the boards use the same sound chips (YM2151), so i guess that the main bottleneck here is the emulation of the V30 chip.

Of course... the "problem" is an extremely slow V30 emulation (the NEC V30 is an x86 CPU, very similar to the Intel 8086; the V33 is a more efficient V30 with a separate data and address bus).

Hello d_smagin & thx for your wonderfull work on fba.
Just a question, would it be possible to add analog compatibility on all games (not just those who actually are analog to start with, like out run...)
It can be very usefull to play some good old gradius and other shooters without the atrocious dpad of the zero. Can a "analog for all games" On - Off be added to theoption menu?

Thx

In Taito's Arkanoid (arkanoid) and in the respective clones the directional controls don't work, in other words it's impossible move the paddle...
Mario Bros (mario) doesn't run, while his clone "Pest Place" (pestplce) works properly...

Another issue: If you set the "show roms" option of the frontend to "Playable only", the list is always empty.

and a question: Would it be feasible to implement an option to show only "parent" roms?

btw, here is a preview pack i've done for FBA. The previews are in PNG format, so you must remove any previous BMP preview if you don't want your old ones to conflict with this new ones.

copy the PNG previews from the zip file into your "local/home/.fba/previews" folder.

Were these run through optipng or pngcrush? I have an optimized pack via optipng -o9 that I can make available. It saves a few megabytes.

Thanks!

is creating a folder with a name starting in a "." possible though? .fba doesn't seem to want to happen for me..
found it.. :-D

Yes, it's technically quite possible. I'll see what I can do.

Yes, this is a bug with arkanoid, official FBA runs it well. I'll investigate this.
As for mario and pestplce, it's the same with official FBA: the second runs, the first doesn't.

Another issue: If you set the "show roms" option of the frontend to "Playable only", the list is always empty.

Sorry, it's a leftover from Capex; to be removed/changed soon.

tmnt2 is susceptible to a weird bug that causes layers to not be rendered, apparently at random. For instance, on Stage 1, Krang's "electrifying vision" is not always drawn onscreen.

Probably, the bug of official FBA. Not the highest priority atm.

but, in the upcoming MAME4ALL by Alekmaul, games which use the V30 CPU (like Dynablaster) run fullspeed...

maybe d_smagin can take the v30 core from MAME4All and implement an option in the menu to change between the current (slow and accurate) one and the fast one from mame4all, pretty much like it is done with the 68k cores.

Nec emulators are almost the same in FBA and Mame; alekmaul's mame4all just uses older version. Probably, there's something else that is causing slowdowns. To be investigated in future.

Thanks everybody for reports. Don't get me wrong, but optimizing emulation or fixing/adding games are not the highest priority for me. The bugs of FBA frontend and GCW0-specific code are.

Yes, probably the GCW Zero has the adequate computing power to run Irem M7x and M9x games at full speed, the point is discover where is the "bottleneck" in the emulation.

We thank you for your work!

A suggestion for the next FBA update:
I noted that often the volume is very different from game to game, I don't know if it's easy to add, but I think that an option to regolate the volume (audio dB) for each game could be useful... thanks!
