Subject: Chrono Cross interlace fix (ePSXe version)

GameShark Lite needs GPUSTATUS_READYFORVRAM off when not IDLE. Also fixes CDROM swapping.
- Enable 'Fake GPU Busy States' to work
- Perhaps we should fix PEOPS GPU to turn off READYFORVRAM instead of gpu.c (my temp solution)

Please add gpu.c / gpu.h to your makefiles.
