Periodic several second freezes with Raspberry Pi 3

This looks to be the issue. I had PPSSPP save this to a tmpfs and everything runs smooth now.

I changed the block at https://github.com/hrydgard/ppsspp/blob/...na.cpp#L93 from:

Code:

#ifndef _WIN32
// do not make this "static"
#ifdef MAEMO
std::string ram_temp_file = "/home/user/gc_mem.tmp";
#elif defined(BB)
std::string ram_temp_file = "/home/root/gc_mem.tmp";
#else
std::string ram_temp_file = "/tmp/gc_mem.tmp";
#endif
#elif !defined(_XBOX)
SYSTEM_INFO sysInfo;
#endif

to

Code:

#ifndef _WIN32
// do not make this "static"
#ifdef MAEMO
std::string ram_temp_file = "/home/user/gc_mem.tmp";
#elif defined(BB)
std::string ram_temp_file = "/home/root/gc_mem.tmp";
#elif defined(RPI)
std::string ram_temp_file = "/dev/shm/gc_mem.tmp";
#else
std::string ram_temp_file = "/tmp/gc_mem.tmp";
#endif
#elif !defined(_XBOX)
SYSTEM_INFO sysInfo;
#endif

I'm not quite sure if this should be based on RPI or RASPBIAN being defined. I don't feel like playing around with other distros tonight.
