@mike8906 if you have the .38 set you don't need to worry about the .dats - they are for people who want to build (or check) that set. you can just put the bios and game files from the download into your roms directory and it should just work :)

You meant 0.78, right? ;-)

Well, i managed to rebuild the roms, but the question is now - should I rebuild the neogeo.zip bios file as well?

@meleu ".38 set" -> I think he means romset for FBA v 0.2.97.38.

like i said, you don't need to rebuild anything. you downloaded the set you need.

I'm using lr-fba-next (now called lr-fbalpha) with the correct romset and those games you mentioned work fine. I didn't update my FBA emulator because if I do I need to "update" the games. I just downloaded the correct romset, uploaded them to the Pi and no need to convert them.

Hello there,

I have managed to sort the issue out, I just downloaded the right rom set as you guys advised - Big thank you for that!!. Mostly satisfied but one thing bothers me. Do you experience a framerate drop when lots of action happen while playing any MetalSlug game? Is it realted to the limitation of the Raspberry Pi3? Or can it be fixed?
I use a memory split of 320 as advised in one of the retropie setup tutorial.
Does the game really requires so much power that it slows down while lots of explosions/enemies appear on the screen?

From the RGUI menu you can "overclock" the NeoGeo. I did that and it works perfectly. I heard that on the original console it lagged too, it's not really the RPi's fault. Still that game is freaking addictive and one of my favorite arcade games.
