i was wondering how i can save slots on my game to continue from my last checkpoint because is difficult for me to start from scratch most of my games that i have like castlevania, etc can someone help me with this?
Shift+Menu should open RetroArch. From there you can select save slots, save and load states, etc.
Set up a hot key for it. Save and Load are real simple with a hot key. I use Shift + L1/R1 bit you can use any button.
