gpSP 1.2.3 (for MiyooCFW)

IMPROVEMENTS:

This is just a stable release using newer GCC, recompiled with latest SDK to be compatible with current 2.0.0 CFW.

ISSUES:

• savestate screenshots are distorted

NOTES:

• default directory for ROMs is /mnt/roms/GBA/
• this is a compatible build, with static musl libs (works also on uclibc img) and PGO optimization
• installing instructions on repo's readme
