Issue description

Using Libretro Mame as the emulator. Settings in Emulationstation set to Not increment/Use existing save. When you save a game in Slot 0 it will save it Slot 1. If you save again it will save to Slot 2. It will always save to the next Slot. It will also Load from the next Slot instead of the current. So if you are on Slot 0, then reload, it will load Slot 1 instead. Load again, it will load Slot 2, etc.

Others have reported this issue, it still remains as of v39. The last version I used where savestates in libretro Mame work correctly was v33.

Please fix someone!.

Detailed reproduction steps

Set Mame Emulator as Libretro Mame. Set savestates to Not increment/Keep existing save. Start a Mame game. When you save a game in Slot 0 it will save it Slot 1. If you save again it will save to Slot 2. It will always save to the next Slot. It will also Load from the next Slot instead of the current. So if you are on Slot 0, then reload, it will load Slot 1 instead. Load again, it will load Slot 2, etc. This issue has persisted for the last 5 versions and remains unfixed.
