CaptainCPS: nice find! 
For fun, it would be nice to find the reason behind the driver callback to GetZipName() failing on PS3. 
The first person to do this gets 250 points! 

best regards,

Some clarification : when you want to load a non-arcade game in libretro-fbalpha, let's say superman on megadrive, you call "md_superman" from the command line, but the zip file is supposed to be called superman.zip, not md_superman.zip.

Your fix change this behavior (the zip file called will be md_superman.zip instead of superman.zip), i don't really mind, but i don't think that's how fba standalone works, even from the command line.

Btw thanks, while checking this issue i noticed some of the non-arcade stuff will crash at -O3 optimization, i'll have to spam dink again with sanitizer debug log  .

Edit : it seems only megadrive is affected, i'll post the debug log here, i'm not even sure debugging is needed if you are currently rewriting the megadrive driver

src/burn/snd/fm.c:1147:68: runtime error: left shift of negative value -6300I'm having issues with loading msx games though, i'll try to find out the reason.

Edit2 : i just never hooked msx to the generation of driverlist.h in libretro-fbalpha's makefile ... My bad, fixed now.

@CaptainCPS : my latest commits on libretro-fbalpha should allow the core to search for md_superman.zip if superman.zip is not present, while leaving fba standalone code untouched.

Nice, I merged your updates in my repo, I will remove my code when I get back home from work.

And yes, I do understand the way FBA looks for zipname, in the full FBA romset they are structured as:

*romsetdir*/megadriv
*romsetdir*/sms
*romsetdir*/roms <--- (arcade roms)
etc...

so the equivalent game on different systems that have same zipname will be located accordingly, even when the driver has the console prefix (md_, gg_, cv_, etc)

I disabled that behaviour with my "fix" while I had time to properly solve it and because I just wanted to make sure at that time that there were no emulation issues with those drivers.

But now that you fixed the zipname issue in libretro, all is good.

SeeYa!

@CaptainCPS : I added another commit to handle this better, part of the commit is to fix the megadrive issue i had with -O3 and gcc-4.8+ but i don't think you are affected since you are using the new driver and a different compiler.

Nice!, I will keep following your repo, I removed the megadrive updates from dink yesterday to respect the official FBA project. When they do the official release then we can work on that source base, with all the upstream updates, fixes, etc.

Btw, is NeoGeo CD implemented in libretro? I think I can collaborate at some point.

@dink or @iq, do you guys think Midway Wolf Unit source files could be modified so it doesnt require c++11? or it is really neccesary to keep it that way? PS3 SDK doesn't support C++11.

SeeYa!

NeoGeo CD is not implemented in libretro, it wasn't in the previous core and i never found out the time and motivation to work on it. You would make tons of people happy if you were able to hook it into the core, that's something people asked a lot.

I think there are a few other platform that doesn't support C++11, that's part of the reason Midway is disabled in libretro (the other reason is that i failed getting it to work even with gcc on my x86_64, but i didn't spend a lot of time on this since C++11 was a real issue for the libretro peoples)

Yeah my ole Xbox compiler didn't like C++11 either but those Midway Wolf Unit games are still in a WIP state just now eg some
games have issues and none of them have sound currantly, maybe better to wait until such a time as they're perfectly Emulated
before putting in the graft required to convert the source files to plain ole C++.
