## Bringing it Together
-The audio/video system uses a double buffered I2S DMA to send video data line by line to the DAC. The interrupt keeps time at the line rate (15720hz for NTSC, 15600hz for PAL). A single audio sample is fed to the LED PWM and a single line of video is converted from index color to phase/amplitude at each interrupt. The IR input pin is scanned and the various IR state machines advanced on changes.

A single audio sample is fed to the LED PWM and a single line of video is converted from index color to phase/amplitude at each interrupt. The hard wired input pin is scanned as well
This a/v pump is fed by the emulator running asynchronously producing frames of video and audio. The emulator may be running on a different core and may occasionally take longer than a frame time to produce a frame (SPI paging / FS etc). The interrupt driven pump won't care, it just keeps emitting the last frame.

Short answer is you don't. When a large cart is selected it gets copied into `CrapFS`; an aptly named simple filesystem that takes over the `app1` partition at first boot. One copied `CrapFS` uses `esp_partition_mmap()` to map the part of the partition occupied by the cartridge into the data space of the CPU.
-> We are using an Audio PLL to create color composite video and a LED PWM peripheral to make the audio, a Bluetooth radio or a single GPIO pin for the joysticks and keyboard, and gpio for the IR even though there is a perfectly good peripheral for that. We are using virtual memory on a microcontroller. And it all fits on a single core. Oh how I love the ESP32.

+**ESP_8_BIT** supports Bluetooth Classic/EDR keyboards and WiiMotes along with either a classic NES or SNES controller
**On boot the software searches for new Bluetooth devices for 5 seconds**; if the device is in pairing mode the software should find it and display its name at the bottom of the screen. Some keyboards will require you to enter a "0000" to establish the connection the first time. WiiMotes should automatically pair and reconnect. WiiMote Classic controllers are also supported.
![Input Devices](img/inputdevices.jpg)
-A number of IR input devices are supported if to add a optional IR receiver (TSOP38238, TSOP4838 or equivalent) to pin 0. The IR Wireless Controllers from Atari Flashback 4 work well and have that classic Atari joystick feel. Retron IR controllers are supported as are WebTV keyboards that come in various guises: WebTV, MsnTV, Displayer, UltimateTV etc. They all should work just fine. A few places have the nice Philips variant new for $11.95 w/ free shipping (search for 'SWK-8630'). If you made a [ZorkDuino](https://hackaday.com/2014/04/30/the-zorkduino/) you will have one of these.

# Time to Play
If you would like to upload your own media copy them into the appropriate subfolder named for each of the emulators in the data folder. Note that the SPIFFS filesystem is fussy about filenames, keep them short, no spaces allowed. Use '[ESP32 Sketch Data Upload](https://randomnerdtutorials.com/install-esp32-filesystem-uploader-arduino-ide/)' from the 'Tools' menu to copy a prepared data folder to ESP32.
