CheezyEmu for AMD & FSR 4

Q: Why is my FPS low with FSR 4 on an AMD RX 6000 or RX 7000 GPU?

README.txt notes that FSR 4’s neural network is heavy on RDNA 2 (RX 6000) and RDNA 3 (RX 7000) because they lack RX 9000’s dedicated AI hardware. Untick “Use AMD FSR 4 in place of a game’s DLSS” in Graphics to drop back to lightweight FSR 3.1 while keeping AMD Frame Generation active, and untick the “Max Resolution (built-in)” add-on on weaker PCs.

Q: Where do CheezyEmu shader packs and nx2_switches.txt go?

Place custom switches in %APPDATA%\eden\nx2_switches.txt so updates do not overwrite them. Ocarina of Time shader packs (cache version fork-v54) go in %APPDATA%\eden\cache\shader\0400486024dec000\ as vulkan.fork-v54.bin (and optional vulkan_used.fork-v54.bin); never copy someone else’s binaries or pipelines files.

Q: How do I fix error 1455 or save-loading crashes on 16 GB RAM?

README.txt states that error 1455 or “over the memory budget” in eden_log.txt means Windows ran out of virtual memory. Set your SSD page file to 32768 MB initial / 49152 MB maximum, set VRAM Usage Mode to Conservative, and close browsers or overlays while playing.

CheezyEmu is CheezerWheezer’s open-source Switch and Switch 2 emulator tuned for AMD Radeon graphics cards (while also running on NVIDIA and Intel). Originally known in the community as the “AMD Superior” fork of Lichii build 117, it rebranded to CheezyEmu in build 10 with saved disk shaders, AMD FSR 4 & FSR 3.1 upscaling, 2x AMD Frame Generation, Steam Deck / ROG Ally black-screen fixes, and automatic Switch 2 game cover art. Checked against GitHub on November 10, 2026.

Emulator only. No games, keys or firmware are included. Upgrading from “AMD Superior” build 9 requires a one-time manual download because the executable changed to cheezyemu.exe; existing saves and shader caches stay intact.

What changed in CheezyEmu build 10

Rebranded to CheezyEmu: new warm-charcoal and cheese-yellow theme, icon and cheezyemu.exe executable, plus an automatic startup updater for Windows zips and Linux AppImages going forward.
Unified AMD FSR & Frame Generation panel: placed at the top of Graphics (and per-game properties) with Ocarina of Time FSR presets (Native AA, Quality, Balanced, Performance, Ultra Performance).
Automatic FSR 4 black-screen fallback: if FSR 4 renders a black frame on an older or incompatible driver, build 10 detects it within seconds and switches itself to FSR 3.1 automatically.
Ocarina of Time visual & handheld PC fixes: Hyrule Field drawbridge and Kokiri Forest fog no longer turn solid white; stale or glowing vertex geometry in Hyrule Field and the graveyard is fixed; Steam Deck and ROG Ally handhelds skip Ocarina’s GPU anti-aliasing network cleanly (“No sharpening”) instead of showing a black screen.
Automatic Switch 2 game cover art: downloads a weekly title-ID-matched SteamGridDB cover list (dist/game_pictures.json) automatically, with right-click options to pick custom art.
Lower boot precache memory & faster NUP loading: plus safe handling of missing/broken microphones, detailed shutdown-step logging, and GPU crash diagnostics (RADV_DEBUG=hang tips on Linux).

AMD FSR 4 & Frame Generation setup (Windows)

CheezyEmu’s bundled README.txt documents exact rules for getting sharp upscaling and smooth 60 FPS frame pacing in Ocarina of Time:

Feature	Required settings & GPU rules	Common pitfall & fix
AMD FSR 4 / 3.1 Upscaling	Graphics > Use AMD FSR 4 in place of a game’s DLSS (on by default), Windows only, Resolution = 1X. RX 9000 (and RX 7000 / 6000 on latest Adrenalin) get ML-based FSR 4; other GPUs get FSR 3.1.	At 0.75X or 2X resolution, FSR and AMD Frame Generation turn off automatically. On RX 6000 / 7000, if FSR 4 is too heavy, untick the FSR 4 box to use faster FSR 3.1 while keeping Frame Generation on.
AMD Frame Generation (2x)	Graphics > tick Enable Frame Generation, set type to AMD FSR Frame Generation (Ocarina, restart), keep Resolution = 1X, then close and reopen CheezyEmu. Bottom bar shows `FG AMD FSR 2X`.	Currently works in Ocarina of Time on Windows only (HUD hearts and minimap stay pinned without smearing). Status tags like `(RES 1X)` or `(RESTART)` explain why FG is paused.
Locked 60 FPS recipe	1) Turn FPS Unlock (built-in) add-on OFF (base game stays at 30). 2) Set Frame rate limit (Switch 2) to 60 Hz. 3) Set VSync Mode to FIFO (plus FreeSync if supported).	Do not cap at 30 using FPS Limit—generated frames will land at uneven intervals and feel like 30 FPS.

Shader packs (`fork-v54`) & `nx2_switches.txt` fixes

Shareable shader packs: CheezyEmu saves compiled shaders to disk so each shader compiles only once. For Ocarina of Time, place vulkan.fork-v54.bin (and optional vulkan_used.fork-v54.bin) inside %APPDATA%\eden\cache\shader\0400486024dec000\. Never copy vulkan_binaries or vulkan_pipelines across different PCs.
Custom switches that survive updates: edit %APPDATA%\eden\nx2_switches.txt (remove leading # to enable, restart CheezyEmu):
- EDEN_NX2_KEEP_ASTC=1 — removes thin grid lines on distant ground on some AMD GPUs (uses extra VRAM).
- EDEN_NX2_FLUSH_DRAWS=512 — submits GPU work in larger batches for steadier frame pacing on AMD.
- EDEN_NX2_PRELOAD_ALL_PIPELINES=1 — compiles every saved shader in a pack at boot (~12 minutes once for 20,000 shaders on an i5-12600K), then comment # back out so future boots do not hold ~10 GB of RAM.
16 GB RAM crash fix (error 1455): if CheezyEmu crashes at launch or save load with “over the memory budget”, set your Windows SSD virtual memory page file to 32768 MB initial / 49152 MB maximum and set VRAM Usage Mode to Conservative.

Recommended controllers for Lichii (SDL3 & gyro)

Lichii reads gamepads through SDL3 (including HID command 300 motion). Standard Xbox pads have no gyroscope, so games that use motion aiming or tilt steering (such as Mario Kart World or Ocarina of Time) need a DualSense or aSwitch-style pad, while TMR/Hall sticks prevent drift:

Common questions

What is CheezyEmu?

CheezyEmu is an open-source (GPL-3.0) Nintendo Switch and Switch 2 emulator in github.com/CheezerWheezer/CheezyEmu, tuned for AMD Radeon GPUs while running on NVIDIA and Intel cards as well. According to CHEEZYEMU.md, it started from zortos293/Lichii build 117 (89440b2) as the “AMD Superior” fork and became its own named emulator (`cheezyemu.exe`) with build 10.

Why couldn’t build 9 update to CheezyEmu build 10 automatically?

Because build 10 renamed the project from “AMD Superior” to CheezyEmu (`cheezyemu.exe` and `cheezyemu-*` archive names), the in-app updater in build 9 cannot match the new filenames. Download build 10 once from GitHub Releases; future updates install from inside CheezyEmu automatically, and all existing saves, settings and shader caches in %APPDATA%\eden carry over.

Which GPUs get AMD FSR 4 vs FSR 3.1 in CheezyEmu?

On Windows at 1X resolution, FSR 4 (machine-learning upscaling) runs on Radeon RX 9000 series cards and on RX 7000 / RX 6000 cards with a recent AMD Adrenalin driver. Older Radeon GPUs, NVIDIA and Intel cards automatically receive FSR 3.1. In build 10, if FSR 4 draws a black screen on your driver, CheezyEmu detects it within a few seconds and falls back to FSR 3.1 automatically.

Why is my FPS low with FSR 4 on an AMD RX 6000 or RX 7000 GPU?

README.txt notes that FSR 4’s neural network is heavy on RDNA 2 (RX 6000) and RDNA 3 (RX 7000) because they lack RX 9000’s dedicated AI hardware. Untick “Use AMD FSR 4 in place of a game’s DLSS” in Graphics to drop back to lightweight FSR 3.1 while keeping AMD Frame Generation active, and untick the “Max Resolution (built-in)” add-on on weaker PCs.

How do I get a steady 60 FPS with AMD Frame Generation in Ocarina of Time?

In Graphics, enable Frame Generation, set Frame Generation Type to “AMD FSR Frame Generation (Ocarina, restart)”, keep Resolution at 1X, and restart CheezyEmu. For a locked 60 FPS: (1) turn the “FPS Unlock (built-in)” add-on OFF so the game runs at native 30, (2) set “Frame rate limit (Switch 2)” to 60 Hz, and (3) set VSync Mode to FIFO. Do not cap at 30 using FPS Limit, or generated frames will pace unevenly.

Where do CheezyEmu shader packs and nx2_switches.txt go?

Place custom switches in %APPDATA%\eden\nx2_switches.txt so updates do not overwrite them. Ocarina of Time shader packs (cache version fork-v54) go in %APPDATA%\eden\cache\shader\0400486024dec000\ as vulkan.fork-v54.bin (and optional vulkan_used.fork-v54.bin); never copy someone else’s binaries or pipelines files.

How do I fix error 1455 or save-loading crashes on 16 GB RAM?

README.txt states that error 1455 or “over the memory budget” in eden_log.txt means Windows ran out of virtual memory. Set your SSD page file to 32768 MB initial / 49152 MB maximum, set VRAM Usage Mode to Conservative, and close browsers or overlays while playing.

Does CheezyEmu include games, keys or firmware?

No. The archives contain only the emulator and documentation (`README.txt`, `CHEEZYEMU.md`). Use only games and system files legally dumped from your own console; this site hosts no files and does not link to ROMs, keys or firmware.
