Your only real hope is to try the Java emulators that Vampent made years ago, and that's assuming the LG A380 supports the Java framework that most flip-phone apps use. PhoneScoop doesn't even know what type of CPU is in that phone. In any case, I can't seem to find the Java versions (not Nokia-specific versions) on Vampent's blog anymore, so I'd check out Archive.org's copy of vampent.com instead. In particular, this page of the GBA emulator:

If nothing else, here's something you can use if you want to try his vNES emulator for phones, something tucked away in a .txt file on my hard drive. At this point I don't really consider this piracy. I had Super Mario Brothers running on my Sony-Ericsson w300i flip phone with only 2 frameskip! XD
