I first tried Aero Fighters, the original (a.k.a. Sonic Wings) in the '2x MAME port to find one odd issue-- a crucial emulated audio component seemed to crash shortly into the game, hanging on one note. Sound effects would play but music would not-- so I suspect the Yamaha synth over the Z80 sound processor. I figured it was a bug in just MAME until I tried Aero Fighters 2 and 3 in GnGeo2x-- to find that they exhibit the same behavior! Being based on a lot of the same code, it occurs to me there must be something common in these two emulators' sound implementation that leads to this fault.

Strikers 1945 Plus I've never managed to get functioning in GnGeo2x. There is not even the usual missing ROM error, I'm just thrown back to the menu. This issue continues to plague me after trying 3 different versions of the ROMset with different ROM names. If the names of the binaries in common release packs of this ROMset are incorrect, would anyone happen to know the correct designations to give them? It's a real shame to not see this one working, as it's probably the best vertical shmup on the platform.

At any rate, excellent work and kudos to the developers of these fine programs and thanks for any tips.
 
Pepone is aware of this problem that came from the YM2610 implémentation (not optimised in gngeo). Power Spikes 2 has the same sound problem.

For me Strikers 1945 Plus work perfectly
At 200MHz w/o sound 60fps (between 45 to 60fps) and with sound avreage 29fps (22 to 36fps). At 260MHz with sound average 56fps (46 to 60fps).

for Striker you must have this in the zip file:
