Easter Egg Boot Splash Function

Main splash location

The main retrodeck boot logo called splash in ES-DE is located in:

res/splash.svg

This is used at all times unless it is being overridden by the Easter Egg function.

---

Easter Egg Logic

When an event is active, the system replaces the default splash from either source and overides the desitination splash.

Source /retrodeck/graphics/

`User

~/.local/share/flatpak/app/net.retrodeck.retrodeck/current/active/files/retrodeck/graphics/splash.svg

~/.local/share/flatpak/app/net.retrodeck.retrodeck/current/active/files/retrodeck/graphics/extra_splashes/<Easter Egg splash>.svg

System

/var/lib/flatpak/app/net.retrodeck.retrodeck/current/active/files/retrodeck/graphics/splash.svg

/var/lib/flatpak/app/net.retrodeck.retrodeck/current/active/files/retrodeck/graphics/extra_splashes/<Easter Egg splash>.svg

Destination

The selected splash is copied to:

~/.var/app/net.retrodeck.retrodeck/config/ES-DE/resources/graphics/splash.svg

The file replaces the currently active splash.svg file in this directory.

This override remains active only during the configured date and time window.

---

splash_screens - features.json

The function is part of the config/retrodeck/reference_lists/features.json json.

The splash_screens" looks in the reference .svg files under: res/extra_splashes/ and overrides the bootlogo with one of the .svg files from the referense list.

"splash_screens": {
    "new_year": {
      "start_date": "MMDD",
      "end_date": "MMDD",
      "start_time": "MMDD",
      "end_time": "MMDD",
      "holiday_type": "stable",
      "filename": "placeholder.svg"
      }
    }

Example:

 "splash_screens": {
    "new_year": {
      "start_date": "1231",
      "end_date": "0101",
      "start_time": "0000",
      "end_time": "2359",
      "holiday_type": "stable",
      "filename": "placeholder.svg"
    },
    "up_helly_aa": {
      "start_date": "0127",
      "end_date": "0127",
      "start_time": "0000",
      "end_time": "2359",
      "holiday_type": "dynamic",
      "filename": "rd-up-helly-aa-splash.svg"
    }
  }

Here we show both the New Year and Up Helly Aa

Field Reference

holiday_type

• Allowed Values: stable, dynamic

Value	Meaning
stable	Occurs on the same calendar date every year.
dynamic	Date may change year-to-year.

---

Overlapping Holiday Handling

If a stable (or multi-day dynamic) holiday spans across another holiday’s date range, it is recommended to split and re-declare the remaining span after the conflicting holiday rather than relying on overlap resolution.

This avoids priority ambiguity and ensures deterministic rendering behavior. Single-day holidays should always take precedence over multi-day spans (whether stable or dynamic).

Example (span split to avoid overlap):

"chinese_new_year": {
  "start_date": "0207",
  "end_date": "0208",
  "start_time": "0000",
  "end_time": "2359",
  "holiday_type": "dynamic",
  "filename": "rd-lunar-goat-splash.svg"
},
"carnival": {
  "start_date": "0209",
  "end_date": "0209",
  "start_time": "0001",
  "end_time": "2359",
  "holiday_type": "dynamic",
  "filename": "rd-carnival-splash.svg"
},
"chinese_new_year_2": {
  "start_date": "0210",
  "end_date": "0210",
  "start_time": "0000",
  "end_time": "2359",
  "holiday_type": "dynamic",
  "filename": "rd-lunar-goat-splash.svg"
}

---
