Supports ROM-based games in .pce and .sgx formats, optionally in .zip files
CD emulation via loading CUE or TOC+BIN files (select a system card rom in the options, for versions <= 1.3.0: place syscard.pce in same directory as CUE file)
About Save Games:
A standard .sav file is created for games using internal battery backup memory
Save states are named .ncq for the auto-save slot, and .ncX where X is the slot number for manual saves.
