- Add load_bsram() and save_bsram() calls [Timer Interrrupts] - Add register with flags [Timer0] - Add Timer0 register for its load value, counter and add flag to Timer Interrupt Register
🐛: calling load_bsram() inside loadnes() after loading ROM, breaks the OSD (or the uC)
🐛: Any memory modification after loading NES rom breaks OSD

RV not loading OSD Key is fixed. Only WIP is BSRAM save/load for NES |
