Retroid Pocket Nova: Full Setup Guide (Shaders, PS2, GameCube)

Summary of technological concepts & setup guide (Retroid Pocket Nova)

What the video is for

A full setup guide for getting the Retroid Pocket Nova from first boot to actually playing retro consoles—especially 4:3 systems—with correct shader looks, solid PS2, and GameCube performance. It also covers BFI (black frame insertion) and a color/saturation tuning tip for the Nova’s AMOLED screen.

1) First boot / Android setup (device performance + storage)

First-boot wizard

On first boot, the Nova runs a setup wizard:

• Choose language
• Connect Wi‑Fi
• Check updates

Performance modes (Android swipe-down menu)

The video emphasizes tuning performance depending on the system:

• Standard / Performance / High performance
• The lowest mode is recommended especially for N64 and below, with better battery life.
• A medium mode is positioned as the best balance for PS2 and GameCube, including upscaling.

Cooling

• Set the fan to “smart” for quiet operation while staying cool.

MicroSD handling (new card workflow)

If the SD card is new:

• Format it in the device
• Set it up as Portable storage (not internal)
• Benefit: enables hot-swapping
• Requirement: use a logical ROM folder structure

Recommended ROM folder structure

• Create a /ROMs folder at the card root
• Add subfolders per system (example: GBA, SNES, etc.)

---

2) Front-end recommendation (console-like UI)

The device can technically run without a front-end, but it’s recommended for a more console-like experience. Options mentioned:

• Daijisho
• Kakao
• ES-DE (EmulationStation for Android): paid app (small cost), praised for a console-style experience

---

3) RetroArch shaders + correct shader installation (CRT look)

The video argues that shaders are often skipped, but they significantly improve the screen’s “retro CRT-era” look—especially on a modern panel.

Key technical setup steps in RetroArch

1. Use Vulkan as the video driver

   • RetroArch: Settings → Video output → Vulkan
   • Vulkan matters here because shader format support is tied to it.

2. Restart RetroArch after changing the driver

3. Download/update shader sets

   • RetroArch: Online Updater → Update slang shaders
   • Shader format discussed: Slang
   • Shader update is described as taking ~60 seconds

Shader concept/goal

Without shaders, many games look “flat” because CRT-era art/design assumed:

• Phosphor glow
• Scanline softening
• Curved glass tube appearance

Example shaders and suggested use cases

• Sony Megatron (HDR folder)

  • Described as heavy/parameter-rich

• Balanced “set-and-forget”

  • CRT Consumer 1W NTSC XL
  • VHS / NTSC VCR (more nostalgic: rolling bar + fuzz)

• Subtle daily-use

  • fake lots
  • CRT Mini Ultra Trinitron (fewer parameters; favored for 16-bit)
  • CRT-Geom (gentle curve + mask)

System-specific recommendations

• NES / SNES / Genesis / PS1 + general 4:3
  • CRT Mini Ultra Trinitron
• Game Boy / Game Boy Color
  • LCD Grid Version 2
  • Notes: avoid oversaturation on AMOLED using color correction shaders
• GBA
  • Mention of saturation correction; prefers LCD 3X
• N64 / Dreamcast and up
  • Suggests CRT Geom
  • Warning: some Vulkan-based shader options may not work depending on the N64 core
  • Workaround: use GSL CRT shaders

Preset saving (common pitfall)

To ensure shader settings stick:

• Use Manage presets → save as Core preset / Global preset
• For a single game: Save game preset

This step is easy to miss, causing shader changes not to “stick.”

4) BFI (Black Frame Insertion) / “smooth motion trick” for 120 Hz

The Nova uses a 120 Hz panel. BFI inserts a black frame between real frames to emulate CRT-like motion clarity.

RetroArch path

• Settings → Video → Synchronization → Black Frame Insertion

Warnings / notes

• Rapid flicker may cause persistence issues on some displays (less likely on OLED)
• Choose the first BFI option designed for 120 Hz panels

Shader stacking with BFI

Because BFI darkens the image, the video recommends stacking shaders, for example:

• Add preset in Quick Menu:
  • Subframe BFI shaders (example: CRT Beam Simulator)
• Optionally append CRT curvature/glow on top (example: CRT-Geom)

Personal verdict from the speaker:

• Some people love it, others turn it off
• Subtle flicker may be noticeable depending on preference

5) Sixth-gen emulation: PS2 and GameCube

PlayStation 2 (Android) — NetherSX2 setup

• NetherSX2 is presented as the standard:
  • Community continuation of AetherSX2
  • Actively maintained and performs well on the Nova’s chip

Alternative mentioned:

• RM SX2 Refresh
  • Moves quickly, adds features like 2nd controller support and improved touch controls

Setup steps:

• Download the APK from the official GitHub (avoid mirror sites)
• Requires a BIOS from your own console (not provided)

Core settings advice:

• Enable Vulkan renderer
• Resolution scaling:
  • Start at 3x
  • Adjust down to 2x or 2.5x depending on the game
• Upside for 4:3 devices:
  • Helps avoid black bars and stretching (fits edge-to-edge)

PS2 shaders approach:

• Not heavy CRT masks (those are more SNES-focused)
• Use a light scanline / CRT-like post effect
• Rationale:
  • Upscaling can make games too sharp and reveal low-res textures
  • Subtle scanlines soften like a CRT
• Example effect:
  • lots CRT used with Super Robot Wars, described as adding warmth/coziness and improving “anime battle” pop

GameCube — Dolphin setup

• Uses the official Dolphin build (via Play Store)
• Praised as stable (no forks needed)

Backend recommendation:

• OpenGL for compatibility
• Can switch to Vulkan if needed

Resolution:

• Start around 2x as a “sweet spot,” but 3x works for many games

Shaders:

• Uses specialized shaders
• Recommends pre-compiling shaders to avoid in-game hiccups
• Mentions “Uber shaders,” but the speaker observed random errors on this chipset

Other visual improvement:

• Anisotropic filtering 2x (low overhead, “free” quality bump)

Aspect ratio note:

• Nova is native 4:3, which reduces common issues GameCube can face on wide-screen handhelds

Coverage claim:

• Capable of playing ~99.9% of the library upscaled without issues (example cited: Star Wars: Rogue Squadron II)

---

6) AMOLED color tuning: saturation correction

Why saturation adjustment is needed

• AMOLED covers ~150% of sRGB, so games can look “hot” (over-saturated reds/greens).

Fix

• Install Odin Tools
• Use the saturation slider:
  • Default: 1.0
  • Recommended: around 0.7 for closer sRGB accuracy

The speaker demonstrates (example: Super Mario World), noting:

• Differences are often clearer in menus than gameplay
• They personally prefer adjusting shader settings for results that stand out more

7) Other consoles, features, and performance notes

DS / 3DS

• Emulation runs well up to 3x–4x
• Dual-screen add-on support is mentioned as an option

PSP

• “Runs like a dream”
• Increase resolution to 1080p
• Expect letterboxing because PSP is 16:9 while the Nova is 4:3

RetroAchievements

• Sign up on the RetroAchievements website
• Pop-up achievements across many supported systems (from RetroArch through GameCube/PS2)

Battery expectations

• Low mode helps battery significantly:
  • Described as “all day and all night” for 90s consoles
• For PS2/GameCube with shaders:
  • Recharge recommended after roughly 5–6 hours (speaker’s weekend-based testing)
