According to r/emulationonandroid, Retroarch or Neo.emu are your best bet for NeoGeo emulation, not sure about Capcom games. Linkme: Neo.emu, Retroarch

I use this EMU on Android & NeoRAGEx on PC, when installed.
The files stay compressed in both instances, regardless of source.
I use this on my Shield when need be.
There's likely also a Retroarch core, and there's the free version of NEO.emu by V Android (outdated).
Thanks for bringing this to my attention, I haven't added NG emulators to the wiki, I'll have to fix that, can't believe I missed it.
