FAQ

Click the game window once. This gives the emulator keyboard focus and enables its controls. Click outside the player when you want to release the controls and use the rest of the page normally.

The game window may have lost focus after you clicked elsewhere on the page, opened a menu, or switched browser tabs. Click the game window again. If that does not help, close any open emulator menu and check that your current bindings still appear in the Controls section below the player.

Click the game window, open Control Settings from the emulator menu, and change the bindings there. The Controls section below the player updates to show the keys that are currently assigned.

The Controls section reflects the bindings currently loaded in the emulator. It changes when you edit a binding or load a saved controls profile, while the action descriptions remain specific to the game.

Yes. Connect a controller recognized by your browser and use the emulator’s gamepad and control settings. Browser and operating-system support still determines whether a particular controller is detected correctly.

Yes, when the game itself supports local multiplayer. Player controls can be assigned to different keyboard keys or compatible controllers. A game marked for multiple players may still require selecting its multiplayer mode inside the game.

They use the emulator’s own state slots in your current browser. Quick Save captures the current moment in the game, and Quick Load restores the selected slot. These local emulator states are separate from the account-based Cloud Save feature.

Yes. Use the emulator’s save-file or state import control. If the game does not update immediately after an in-game save file is imported, restart the game as the emulator message suggests. Importing a file into the emulator does not automatically upload it to your 1UPHeart account.

Emulator saves and Quick Save slots belong to the emulator in your current browser or device. They can be lost if that browser’s site data is cleared. A cloud save is a save state stored under your 1UPHeart account on the server, so you can load it from another compatible device after signing in.

Yes. The game itself remains playable without an account, but Cloud Save and Cloud Load need a signed-in account so the save can be stored privately under the correct user.

The emulator must be running before it can produce or accept a save state. Start the game and wait until it is playable, then use Save Progress or Load Progress.

A regular account can keep one cloud save in total. Saving progress for another game asks you to replace the existing save rather than silently deleting it.

An active Supporter can keep one cloud save for every exact ROM version. This allows saves for multiple games and for distinct regional versions without using one global account slot.

Not for the same exact ROM. Each exact ROM version has one cloud-save slot, so saving it again overwrites that ROM’s previous cloud save after confirmation. A genuinely different regional ROM is treated as a different version and receives its own slot.

Yes. Cloud-save compatibility is based on the normalized ROM file and emulator core, not the language of the page. If several translated posts launch the same ROM, they use the same cloud save.

Yes. A USA, European, Japanese, or translated ROM with a different file is a separate game version. Supporters can keep one cloud save for each of those exact ROMs. Regular accounts still have the one-save account limit.

Save states are tied to the exact ROM and emulator core that created them. Even closely related regional releases can have different data layouts. The site blocks an incompatible load instead of risking a crash or corrupted progress.

The existing server file for that slot is replaced by the current emulator state. The site shows an inline confirmation before doing this. Overwriting cannot be undone, so download the old save first if you want to keep a backup.

Open the Saves section of your account. Each save shows the game page, ROM filename, language, and saved date, with controls to return to the game, download the file, or delete it.

Yes. Sign in to the same account, open a page that launches the same ROM version, start the emulator, and select Load Progress. A different ROM or emulator core will not accept the save.

No. Files can be imported through the emulator for local use, but the website does not accept arbitrary file uploads into cloud storage. To create a cloud save, run the game, import or load the compatible state if needed, and then press Save Progress.

No. Deleting a save removes both its account record and server file. Download a copy before deleting anything you may want later.

A controls profile is a server-side copy of your current emulator bindings for one console. It lets you restore those bindings after changing device or browser instead of configuring every player again.

Start a game for the console, configure its bindings in Control Settings, and use Save Controls below the player. Use Load Controls on any game using the same console profile to apply the saved bindings.

A regular account can keep one controls profile in total. Saving controls for another console requires replacing the existing profile after confirmation.

An active Supporter can keep one profile for every console currently supported by the emulator plugin. Each console has its own profile because its buttons and default layout can differ.

No. Each console has one server-side controls profile per account, and saving it again overwrites the previous version after confirmation. If multiple profiles for one console would improve your setup, let us know in the comments.

Yes. The saved profile can include the current bindings for Players 1 through 4, including directional controls and supported console buttons.

Yes, when those games use the same console profile. For example, a saved Game Boy Advance profile can be loaded on another Game Boy Advance game. It is not applied to NES, SNES, or Sega Genesis games because those consoles have separate profiles.

Yes. The keycaps shown below the game update when the emulator reports a changed binding or when a controls profile is loaded. The localized action descriptions still come from the current game post.

Open the Saves section of your account. Controls profiles appear below the game saves and can be deleted there.

Existing profiles are not automatically deleted. Your account returns to the regular one-profile limit, so creating a profile for another console may require replacing a saved profile.

No. You can play without signing in. An account is required for Favorites, server-side Cloud Saves, saved controls profiles, and Supporter features.

Yes. The standard login form accepts either the username or email address attached to your 1UPHeart account.

Google sign-in uses a verified email address and Google’s account identifier to create or link your 1UPHeart account. If a new account is needed, the website generates a unique username from the email address. It does not request access to Google Drive, contacts, or unrelated Google data.

The verified Google identity is linked to the existing account with that email address rather than creating a duplicate account.

Yes. Password changes in Account Settings affect username or email login. Google sign-in remains a separate way to access the same linked account.

Use the Save to Favorites button on a game page. Press it again to remove the game, or remove it from the Favorite Games section of your account.

Yes. Favorites are stored with your account, so the same list appears after you sign in on another device.

It includes one cloud save for every exact game version, one controls profile for every supported console, a personal avatar, and an ad-free experience. It also directly supports the operation and growth of 1UPHeart.

The monthly plan is $3.99 USD per month. The annual plan is $39.99 USD per year. Current prices are also shown in the Supporter section before checkout.

No. Both plans unlock the same Supporter features. They differ only in billing period and price.

Yes. Monthly and annual subscriptions renew at the end of their billing period until they are cancelled. Your account shows the next renewal date while the subscription remains active.

Stripe handles checkout, payment methods, invoices, renewals, and cancellation. 1UPHeart receives the subscription status needed to enable account features but does not store your full card details on the website.

Open the Supporter section of your account and select Manage Billing. This opens Stripe’s secure customer portal for payment methods, invoices, plan management, and cancellation.

Open the Supporter section, select Manage Billing, and cancel through Stripe’s customer portal. The account page then shows that cancellation is scheduled and states when Supporter access will end.

No. Access continues through the paid billing period and ends on the date shown in your account and Stripe portal.

Your existing cloud saves remain available. The account returns to the regular saving limit, so creating a save for a new game may require replacing one. You can continue to view, load, download, or delete compatible existing saves.

Yes. Active Supporter accounts are ad-free.

No. Gameplay access is free. Supporter pays for expanded account features and helps fund the service; it does not sell game content, ROM downloads, virtual currency, or prizes.

Personal avatar upload is available while the account has active Supporter access. The avatar manager appears in the Supporter section of the account.

Use a JPG, PNG, or WebP image no larger than 5 MB. The source image must be at least 128 by 128 pixels.

The avatar editor lets you move and resize a square crop within the source image. The website then processes that crop into a 128 by 128 pixel PNG for consistent display.

Your avatar is public and appears in the account control in the site header and beside your comments. Do not upload an image you do not want other visitors to see.

The website uses the Supporter crown as the default Supporter account icon. If a custom avatar is present, the crown appears as a Supporter indicator when the header avatar is hovered.

The custom Supporter avatar stops being displayed and the normal signed-in account icon returns. You can also remove your custom avatar manually from the Supporter section while the avatar manager is available.

Some games have distinct USA, European, Japanese, or translated releases. A localized game page can use the regional ROM that best suits its audience instead of forcing every language to launch the English version.

No. The page interface and description can be localized even when no separate ROM exists for that language. The language shown inside the game depends on the actual regional or translated ROM assigned to that page.

Check the Version field on the game page. It shows the ROM filename without the full server path, including available region, translation, revision, or other version information encoded in that filename.

Only when those pages launch the same exact ROM with the same emulator core. Pages using a different regional or translated ROM require a separate compatible save.

No. Controls profiles are console-specific. A profile can be loaded across translated game pages that use the same console profile, even when their page language or ROM version differs.

Leave a comment on the affected game page. Include the game version shown on the page, your browser and device, what you expected, what happened instead, and the steps that reproduce the problem.

Leave a comment on that game page and describe the incorrect item and the correction you recommend. Keeping the report on the affected page makes the game and ROM version unambiguous.

Use the comments. For a game-specific request, comment on the closest relevant game page. For a broader feature request, leave a clear comment explaining the workflow you want and why it would help.

No. On game pages, a name and comment are required, while email is optional. Signed-in users can comment through their account identity, and active Supporter avatars appear with their comments.
