Implemented savestates #140

• Up to 5 manual save state slots per game, accessible via the in-game menu (SELECT + START).
• In-game quick savestate Save/Restore via (START + DOWN) and (START + UP).
• Auto Save can be enabled per game, which allows to save the current state when exiting to the menu. When the game is launched, player can choose to restore that state.

When loading a state, the game mostly resumes paused. Press START to continue playing.

Save States should work for mapper 0,1,2,3 and 4. Other mappers may or may not work. Below the games that use these mappers.

• https://nesdir.github.io/mapper2.html
• https://nesdir.github.io/mapper3.html
• https://nesdir.github.io/mapper4.html

The mapper number is also shown in the Save State screen.

Fixes

• Fruit Jam audio fixes.
• Settings changed by in-game button combos are saved when exiting to menu.
• DVI audio volume was somewhat too low, fixed. #146

Downloads by configuration

Binaries for each configuration are listed below. Binaries for Pico(2) also work for Pico(2)-w. No blinking led however on the -w boards. For some configurations risc-v binaries are available. It is recommended however to use the arm binaries.

[!NOTE] No dedicated binaries are provided for the Pico w or Pico 2w. Instead, use the Pico or Pico 2 binaries. Enabling the LED on these boards causes too many issues. #136

[!NOTE] On Pico W and Pico2 W, the CYW43 driver (used only for blinking the onboard LED) causes a DMA conflict with I2S audio on the Pimoroni Pico DV Demo Base, leading to emulator lock-ups. For now, no Pico W or Pico2 W binaries are provided; please use the Pico or Pico2 binaries instead. (#132)
