Features

Six consoles

• Super Nintendo with Snes9x 1.63: SuperFX, SA-1, DSP and the other chips, hi-res modes, up to 5 players with the Super Multitap.
• NES and the Famicom Disk System with FCEUmm: palettes, turbo, NTSC filter.
• Nintendo 64 with Mupen64Plus-Next, ParaLLEl-RDP (the PS4's GPU draws at 1x, 2x or 4x) and ParaLLEl-RSP, the dynamic recompiler, Controller Pak and Rumble Pak.
• Game Boy, Game Boy Color and Game Boy Advance with mGBA: Game Boy Color or Super Game Boy colours with their borders, screen colour correction, LCD ghosting, the solar (Boktai) and tilt sensors (the right stick, or moving the DualShock 4), rumble, and the cartridges' clock (Pokémon).
• Battery saves written automatically, 8 save-state slots with screenshots, resume where you left off, RetroArch .cht cheats, reset.

Picture

• Quality in one setting: Low, Medium, High or Ultra (the most each console can do).
• GPU Upscaler: Pixel Art HD (xBRZ), AI (xBRZ + the Anime4K neural network), Smooth HD (AMD FSR) and HD Sharpen (AMD RCAS), at the TV's resolution.
• Resolution 2x–6x with xBRZ, HQx or Sharp Pixels; aspect ratio, integer scaling, zoom, scanlines (on the Game Boys, the grid of their screen), NTSC filter, V-Sync.
• Bezels: three per console plus a retro TV (the Game Boys shaped like each handheld), or your own.

A launcher like a console's

• Two menu styles: Library (box art in a row, a tab per console on L1 / R1) and XMB (the PSP-style columns), 12 colour themes or your own wallpapers, 8-bit sounds.
• Box art, automatically from libretro's thumbnail server (GoodSNES and No-Intro names).
• Favorites, search, sorting (A–Z, recently played, region, console), a default game, a folder browser, Clean Up Games and 13 languages.
• Every setting for all games, for a console or for one game, with a short explanation of each option, and button remapping.

Requirements

• A PS4 with GoldHEN (any model).
• Your own games (.zip works too):

  Console	Files
  Super Nintendo	.sfc .smc .swc .fig .bs
  NES	.nes .fds .unf
  Nintendo 64	.z64 .n64 .v64
  Game Boy	.gb .sgb
  Game Boy Color	.gbc (and the .gb files you put in its folder, like Pokémon Yellow)
  Game Boy Advance	.gba

• Internet on the PS4 for the box art (optional).

Installation

1. Download EmuSuNi-vXX.YY.pkg from the latest release.
2. Copy it to a USB drive (FAT32 or exFAT), for example in a PKG folder.
3. On the PS4, install it with GoldHEN's Package Installer (or Settings → Debug Settings → Game → Package Installer).
4. Start EmuSuNi from the home screen.

To update, install the new package over the old one: your settings, saves and covers stay in /data/EmuSuNi.

Where the games go

The easiest is a USB drive with a folder per console:

USB drive
└── Roms
    ├── snes    (Super Nintendo)
    ├── nes
    ├── n64
    ├── gb
    ├── gbc
    └── gba

• N64, GB, GBC and GBA look in Roms/n64, Roms/gb, Roms/gbc and Roms/gba on the USB drive without any setup.
• Super Nintendo and NES start in /data/EmuSuNi/games and /data/EmuSuNi/nes (on the PS4, by FTP).
• Any folder works: in Settings → Game Folders you choose each console's, on a USB drive or on the PS4. Subfolders are searched too.
• After copying games, press Square in the Library to look for them again.

Box art

• Downloaded automatically (the PS4 needs internet) from libretro's thumbnail server; the progress shows under Your games. Settings → Download Covers looks again.
• Your own work too: a PNG named like the game's file or its title in /data/EmuSuNi/covers (Super Nintendo) or in its console's subfolder: covers/nes, covers/n64, covers/gb, covers/gbc, covers/gba.
• When one is missing, Triangle → Find Cover shows the closest ones to pick from.

Controls

L3 + R3 (both sticks pressed) opens the in-game menu on every console. Every button can be changed in Settings → Controls (for a console or for one game).

DualShock 4	Super Nintendo	NES	Nintendo 64	Game Boy / Color	Game Boy Advance
Cross	B	B	A	B	B
Circle	A	A	C Down	A	A
Square	Y	Turbo B	B	Turbo B	Turbo B
Triangle	X	Turbo A	C Up	Turbo A	Turbo A
L1 / R1	L / R	Disk side / insert (FDS)	L / R	—	L / R
L2	—	—	Z	—	—
R2	Fast forward	Fast forward	Z	Fast forward	Fast forward
Options	Start	Start	Start	Start	Start
Touchpad	Select	Select	Fast forward	Select	Select
Left stick	D-Pad	D-Pad	Stick	D-Pad	D-Pad
Right stick	—	—	C buttons	Tilt sensor	Tilt sensor

Menu (Library style)
D-Pad Left / Right	Previous / next game (Up / Down: 10 at a time)
L1 / R1	Tabs: All, each console, Favorites, Settings
Cross	Play
Triangle	Game options: favorite, settings, cheats, controls, find cover, rename, information, default game, delete
L2 / R2	Favorite / search
Square	Look for the games again
Options	Sort
Circle	Back

Hold L1 while EmuSuNi starts to open the menu instead of the default game.

Building from source

The build runs on Ubuntu 24.04 (WSL2 works) with clang 21, PacBrew's OpenOrbis toolchain and DolphinPS4's PS4 runtime (libc++ 21 and Mesa's RADV Vulkan driver).

# once: packages, toolchain, libc++, Mesa, the cores and Dear ImGui (as root, ~45 minutes)
sudo -i bash /path/to/EmuSuNi/scripts/setup.sh

# then
EMUSUNI_VERSION=00.19 bash scripts/build.sh   # builds ~/emusuni-build/emusuni_eboot/eboot.bin
bash scripts/package.sh 00.19                 # makes the .pkg in ~/emusuni-build/out

scripts/make-assets.py regenerates the icon, the start-up pictures, the logo and the 8-bit sounds (Python + Pillow); scripts/make-bezels.py the bezels; scripts/make-lang.py the language files.

Under the hood

• Display: Vulkan through Mesa's RADV driver running on the PS4's GNM interface (from DolphinPS4), three 1920×1080 VideoOut buffers. The menus are drawn with Dear ImGui.
• Cores: every emulator is a libretro core linked into the app, its API renamed (snes9x_retro_*, mgba_retro_*...), so one process plays all six consoles.
• Nintendo 64: ParaLLEl-RDP draws on the app's own Vulkan device; its command ring is lock-free and the VI scanout can run on its thread; the emulation and the RDP threads have cores of their own.
• GPU filters: xBRZ, Anime4K and AMD FSR/RCAS run as Vulkan fragment-shader passes before the menu is drawn; their pipelines are compiled in the background and cached.
• Memory: the PS4's system C library serves allocations from a ~12 MiB pool shared with the kernel's own objects. All of the app's allocations — C malloc and C++ new — go to a dlmalloc heap in system flexible memory instead (port/).
• Covers: libretro's thumbnail server over plain HTTP (the PS4's TLS fails on GitHub's servers), with GitHub as a fallback; pictures are shrunk to the size the menu shows.
