App Crashes
Crashes on Launch
App Store users:
Ensure your device is on iOS 16.0+ (Settings → General → About)
Restart your device (full power off → wait 10 seconds → power on)
Delete and reinstall Provenance from the App Store
If it persists, report on GitHub Issues
Sideloaders: If the app worked before but crashes after ~7 days, your provisioning profile has expired. Free Apple Developer accounts expire every 7 days — re-sign with AltStore or Sideloadly. Your saves and ROMs are safe. See Advanced Installation FAQ for details.
Crashes When Importing ROMs
Archives containing folders will crash the app. Archive only loose files — do not include folder structure inside a .zip.
Filenames with extra periods (e.g.,
Game.v1.2.rom) can cause crashes. Rename to remove extra dots before the extension.CD-based / multi-file ROMs should be uploaded one at a time. If importing breaks, delete the game from the app and from the file system (ROMs and Imports folders), then re-upload.
Crashes on Library Screen
This may indicate a corrupted database. Symptoms:
Games appear duplicated
Metadata or artwork missing
Consistent crashes when browsing library
Fix: See Corrupted Database under Large Library Issues.
General Crash Steps
Force quit and restart — Double-tap Home → Swipe up on Provenance → Relaunch
Update to latest version — App Store → Provenance → Update
Restart device — Full power cycle
Reinstall — Delete app → Reinstall from App Store (saves in iCloud are preserved with Provenance Plus)
Performance Issues
Game is Slow or Stuttering
Try these fixes in order:
Close background apps — Double-tap Home, swipe up on all other apps
Disable visual filters — Settings → Turn off Smoothing and CRT Filter
Lower internal resolution — Settings → Resolution Multiplier → 1x or 2x
Enable frameskip — Settings → Frameskip → Auto
Try an alternate core — If available, some cores perform better for certain games
Restart device — Power off for 10 seconds, then power on
Check your build: If the app is named "Prov Debug" on the Home Screen or Settings shows "DEBUG", you built the debug version by mistake. Debug builds have extra logging and no compiler optimizations — they're significantly slower. Rebuild using the Provenance-Release (iOS) or ProvenanceTV-Release (tvOS) scheme.
Specific Game is Slow, Others Are Fine
Some games are inherently demanding (e.g., GoldenEye 007, Conker's Bad Fur Day on N64)
Try a different ROM dump — bad/corrupted ROMs can hurt performance
Check online compatibility lists for the emulator core
Update Provenance — cores improve with each release
Audio Crackling or Popping
This means the CPU can't keep up with the audio buffer.
Enable frameskip (Settings → Frameskip → Auto)
Close apps playing background audio
Switch from Bluetooth to wired headphones/speakers (Bluetooth audio adds latency)
Disable in-game audio settings if available

ROM and Import Issues
ROMs Won't Import
Check file format — See Formatting ROMs for supported formats per system
Don't include folders in archives — Zip only the ROM files, not a folder containing them
Check for extra dots in filenames — Files like
Game.v1.2.romcan cause issues; rename toGame v1-2.romVerify the ROM isn't corrupted — Re-download if the file hash doesn't match known good dumps
Restart Provenance — Force quit and relaunch after importing
Games Missing from Library After Import
Wrong file format — Loose
.binfiles from CD-based games may be detected as Sega Genesis ROMs. Use.cue + .binpairs or.chdformat instead.Missing BIOS — Some systems won't show games without BIOS files. See BIOS Requirements.
ROM in Conflicts folder — If auto-detection fails, the ROM may be in the Conflicts folder. Check via the web server or Files app and move it to the correct system folder.
Re-import — Delete the game from the library, then re-add the ROM.
Multi-Disc Games Not Working
Multi-disc games (e.g., Final Fantasy VII on PS1) require an M3U playlist file:
Create a text file named
GameName.m3uList each disc on its own line:
Import the
.m3ufile along with all disc files
Full guide: Advanced ROM Management
Region Pack ROMs (Multiple Versions in One Archive)
If importing an archive creates multiple identical-looking games, the archive likely contains multiple region versions. Extract the archive, keep only the region you want, re-archive, and re-import.
Black Screen After Launching Game
Missing BIOS — PlayStation, Sega CD, Saturn, and Dreamcast require BIOS files. Check BIOS Requirements.
Corrupted ROM — Try a different dump of the same game.
Wrong core — If multiple cores are available, try switching to an alternate core.
Report it — If the issue persists, report on GitHub Issues with the game name and system.
Controller Issues
Controller Won't Pair
PlayStation / Xbox controllers:
Put controller in pairing mode:
PS4/PS5: Hold Share + PS button until light flashes rapidly
Xbox: Hold Pairing button (top edge) until Xbox logo flashes
On device: Settings → Bluetooth → Select controller
If it doesn't appear, power cycle the controller and try again
MFi controllers: Usually pair automatically when turned on near the device. If not, check Settings → Bluetooth.
Controller Keeps Disconnecting
Check battery — Low battery is the #1 cause of disconnects
Reduce Bluetooth interference — Move WiFi routers, microwave ovens, and other Bluetooth devices away
Apple TV: Use Ethernet — Wired internet frees up the WiFi/Bluetooth antenna, improving stability
Forget and re-pair — Settings → Bluetooth → Tap (i) on controller → Forget This Device → Re-pair
Buttons Not Responding or Wrong Mapping
Update controller firmware — Connect to PS5/Xbox console to update, or use the manufacturer's app (8BitDo Firmware Updater, etc.)
Check MFi profile limitations — MFi controllers lack Select/Start; Provenance maps L2 = Select, R2 = Start for systems that need them
iCade controllers — These use keyboard hacks and have limitations. Only one iCade controller can be used at a time. Cannot use iCade and MFi simultaneously.
Restart the game — Close and relaunch the current game

iCloud Sync Issues
Sync Not Working
Requirements:
Active Provenance Plus subscription (Apple TV gets free CloudKit sync)
Available iCloud storage
Active internet connection on all devices
Same Apple ID signed in on all devices
Fixes:
Toggle sync off and back on — Settings → iCloud Sync → OFF → wait 10 seconds → ON
Force quit Provenance and relaunch
Check iCloud storage — Settings → [Your Name] → iCloud (may be full)
Wait 10-15 minutes — Large libraries take time to sync initially
Sync is Stuck or Slow
Force quit Provenance
Disable iCloud Sync in Provenance settings
Re-enable iCloud Sync
Restart device
Wait 10-15 minutes for the queue to process
"Not Enough iCloud Storage"
Check usage: Settings → [Your Name] → iCloud → Manage Storage
Delete old device backups you no longer need
Upgrade iCloud plan ($0.99/month for 50 GB)
Disable sync for less-played systems to reduce usage
Sync Conflicts Between Devices
Only enable iCloud sync on one version of Provenance (don't sync both App Store and sideloaded versions)
If using multiple devices, let one device finish syncing before starting the other
If saves conflict, the most recent save wins
Full guide: iCloud Sync Troubleshooting
Save Issues
Battery Save Not Loading
Filename must match exactly:
[ROM-Filename].savThe save must be from the same region/version of the ROM — saves are not compatible across different ROM versions
Try re-importing the save file
Save States Not Working After Update
Save state compatibility between app updates is NOT guaranteed. Core updates can change how save states are stored, making old states incompatible.
Best practices:
Before updating Provenance, launch important games and create in-game saves (battery saves) — these are more portable than save states
Save states are tied to the specific emulator core version — switching cores means old states won't load
Battery saves (
.sav/.srm) are the safest long-term save format
Save States from Other Emulators
Save states from RetroArch or other emulators generally won't work unless they use the exact same core version. Battery saves (.srm, .sav) are much more compatible across emulators.

Skin Issues
Skin Not Showing in Browser
Check file extension — must be
.deltaskin, not.zipVerify system compatibility — not all skins support all systems (DS not supported; 3DS not supported on tvOS)
Force quit Provenance and reopen
Re-import the skin
Skin Looks Corrupted or Glitchy
Re-download the skin (may have been corrupted during download)
Check device compatibility (some skins are iPhone-only or iPad-only)
Update Provenance to the latest version
Report to the skin creator via DeltaStyles or GitHub
Buttons Don't Respond with Custom Skin
Check that the skin's
info.jsonhas correct button mappingsToggle "Touch Controls" off and back on in Settings
Try a different skin to isolate if it's skin-specific
Restart the game
Performance Slowdown with Skins
Complex skins with detailed graphics can add overhead. Try a simpler skin, close background apps, and disable CRT/Smoothing filters.

Installation Issues
"Not available in your region"
Use different Apple ID from supported region, or sideload instead
"Not enough storage"
Provenance needs ~2.5 GB + space for games. Free up 10+ GB recommended
Installation stuck
Force-close App Store → Restart device → Try again. Check Apple System Status
Crashes immediately on launch
Ensure iOS 16.0+ → Restart device → Delete and reinstall
"Untrusted Developer"
Settings → General → VPN & Device Management → Trust your profile
App expires after 7 days
Free accounts expire weekly. Re-sign with AltStore/Sideloadly or upgrade to paid $99/year account
"App is already installed"
Delete existing version first, or use a different bundle ID
Cannot authenticate (2FA)
Create an App-Specific Password at appleid.apple.com → Security
Max App ID limit reached
Too many bundle IDs this week. Reuse an existing one, or use a different Apple ID

Large Library Issues
Library Loading is Slow
Delete ROMs you no longer play
Optimize artwork — compress cover images under 500 KB
Clear cache: Settings → Advanced → Clear Cache
Restart device
Temporarily disable iCloud sync while loading
Corrupted Database
Symptoms: Duplicated games, missing metadata, crashes on library screen.
Last resort — this rebuilds your entire library index. Only do this if other fixes haven't worked.
Fix:
Force quit Provenance
Open Files app → On My Device → Provenance
Delete the
Provenance.realmfileRestart Provenance — the library will rebuild automatically (may take 10-30 minutes for large collections)
This does NOT delete your ROMs or saves — only the library index. Your games will be re-scanned and re-imported.
Advanced Debugging
If you're comfortable with developer tools, you can dig deeper into issues:
Viewing Crash Logs (iPhone/iPad)
Go to Settings → Privacy & Security → Analytics & Improvements → Analytics Data
