KNULLI Quick Resume for Pokémon: shutdown and reopen checks

Resume after an update: verify Continue first

Before comparing a restored scene across a KNULLI update, launch the same game normally and inspect Continue. The update verification sequence separates ordinary progress from resume convenience.

1. Record the current emulator and compare it with the pre-update selection.
2. Inspect the resume-related frontend choices and support for that runtime.
3. Preserve the old state if it contains progress not in the ordinary save.
4. Once ordinary progress is secure, test the documented supported shutdown/resume procedure in a harmless scene.
5. Record relaunch, state restoration and Continue as separate results.

If ordinary progress is missing too, return to active storage and save identity. Repeatedly toggling resume cannot establish that the correct cartridge save is being read. This page supplies no cross-version state conversion or measured update result.

Check support before relying on it

The developer warns that some emulators and native games lack auto-save support. Quick Resume can still relaunch them, but saving and loading remain your responsibility. RetroAchievements Hardcore Mode also prevents Quick Resume.

Check the installed emulator and your exact setup. A game returning to its title screen is a different observation from restoration of a previous scene; record which one occurs.

Try a complete shutdown cycle

1. Back up known progress and record KNULLI version, game build and emulator.
2. Make an ordinary Pokémon in-game save at a recognizable location.
3. Enable the two documented settings if the emulator supports the workflow.
4. Use the device's documented graceful shutdown. KNULLI's guide gives a two-second power hold as an example; do not substitute a forced power cut.
5. Power on, inspect the reopened game and verify its location and team.

Then verify Continue through a normal game start separately. This distinguishes a restored session from the cartridge save you might later move to another device.

Sleep versus shutdown

KNULLI recommends graceful shutdown rather than relying on prolonged sleep on its low-powered handheld targets. This is developer guidance, not a Pocket Deal Radar battery measurement for your model.

On the SP, read the lid-close guide before assuming that closing the shell triggers a particular save or shutdown behavior.

A resumed game blocks boot?

The developer's recovery procedure edits system/knulli.conf. Shut down, preserve a copy of that file and keep the existing saves before changing it.

KNULLI says to remove the lines for global.quickresume, bootgame.cmd and bootgame.path, then save and boot again. Remove only the identified entries from the backed-up configuration; this is not a factory reset.

The procedure disables Quick Resume. Investigate the failing game and emulator before deliberately enabling it again. If you cannot identify or read the configuration, stop rather than formatting storage.

Three different outcomes after powering on

This table interprets the visible result; it is not a claim that one symptom has only one cause. Write down the first screen you see before changing settings. A title-screen relaunch can be consistent with the developer's warning about emulators without automatic state support.

For a Pokémon game, use a recognizable team and location. A return to a similar-looking town is weaker evidence than checking the same trainer, party and recent activity together.

Prepare a test you can actually interpret

Choose one game, one emulator and one storage configuration. Keep those fixed for the shutdown check. If you update firmware, switch cores and move SD cards at the same time, a failed result leaves too many possible explanations.

1. Make a baseline: use Pokémon's own Save command and wait for completion. Record trainer, party and location.
2. Secure a separate copy: preserve the known cartridge save and any state containing newer progress. A file still on the working card is not an independent backup.
3. Record the configuration: note KNULLI version, emulator selection, game build and the two resume settings.
4. Choose a harmless scene: avoid testing shutdown during a save animation, a battle decision or an important event.

After that preparation, use the documented full shutdown cycle above. Judge the result from the screen shown on boot and the progress you recognize, rather than from how quickly it appears.

Worked example: Quick Resume opens the title screen

In this example, the cartridge save is showing expected progress. The missing restored scene is a resume question. Check whether the selected emulator supports automatic saving/loading and whether Hardcore Mode is active before replacing any game files.

If you change emulator to investigate support, first preserve progress and keep the original selection recorded. Old states are not automatically portable. Verify the ordinary save with the new emulator before judging its resume behavior.

If Continue instead shows old progress, treat that as a second issue. Retain both observed files and inspect the selected game and active storage; do not assume enabling Quick Resume repairs the cartridge-save path.

Read the recovery configuration without guessing values

The three recovery names above are configuration keys. The developer procedure removes their corresponding lines; it does not ask you to invent replacement paths or a new startup command. Keep a complete copy of the original knulli.conf before the edit.

1. Find the installed configuration: confirm you are looking at the KNULLI storage in use. If you recently changed cards, preserve both and consult the storage guide.
2. Identify the exact keys: inspect the file for the three names in the developer instructions. Do not delete unrelated settings that merely mention a game.
3. Apply only the documented change: remove the relevant lines, save the file and eject readable storage normally before returning it to the device.
4. Check the next boot: the intended result is access to EmulationStation. Then inspect the failing game before deliberately re-enabling resume.

If the expected configuration or keys cannot be identified, stop this procedure and retain the original file. That evidence is more useful for support than a reformatted card or a rewritten configuration you can no longer compare.

A practical stopping routine for a Pokémon session

Once your exact setup passes the test, keep the routine simple: save inside Pokémon when you reach a suitable stopping point, wait for completion, then use graceful shutdown. Quick Resume is a convenience for returning to play, while the ordinary save remains useful for Continue and later migration.

Repeat the brief comparison after a change that affects the emulator, game version or storage. You do not need to test unrelated settings repeatedly. Record the last known working combination so a later difference has a useful baseline.

Quick Resume changed after switching emulator?

A game that reopened yesterday can behave differently after you change its emulator. Identify the current selection before toggling both resume options repeatedly. The KNULLI game-settings reference distinguishes libretro cores from standalone emulators; some standalone paths lack automatic save/load and EmulationStation save integration.

Illustrative case: you change one GBA game's emulator to investigate a launch problem. It now opens successfully, but boots to its title screen. That is a launch result and a resume result. Open Continue and inspect the known party and location as a third result; do not combine them into “everything worked” or “everything failed”.

Keep the original emulator selection recorded. If you compare it again, preserve progress first and use the same game file. A newer scene held only in a state deserves its own investigation before any overwrite; this comparison supplies no state conversion procedure.

For the configuration route, use the setting-owner table. If the changed behavior is a DS screen or cursor action, go to the DS emulator-change check. This runtime distinction was checked in developer documentation on 7 Oct 2026; no physical resume result is supplied.

Keep recovery, settings and migration separate

Use the settings-layer guide for choices that revert and the second-card guide for migration. A successful resumed scene does not establish that files were copied to another card.
