Copy a useful problem report

No room code, saved data or recorded inputs are included.

I cannot start the game

Choose Play now on the home page. The title artwork is only a cover until you click Play.
Click inside the game. Press Enter for the title, then Enter again after the fan-game notice. The mode menu should appear.
Choose Training with W/S and Enter. Use F to confirm your fighter and sidekick. Choose a stage and press Enter. If nothing changes, check the input branch.

The screen is blank or loading is slow

Wait for the game’s own asset loader. The first launch downloads game artwork and audio; this is separate from the website cover.
Open the game in its own window from the player toolbar. If that works, return and focus the embedded game.
If the loader reports a missing file, copy diagnostics below. Reload only when ready to lose the current match. Do not clear browser storage as a first step.

I cannot hear sound

Click or tap inside the game and advance past the title. Browser audio needs a user interaction.
Open Settings from the mode menu. Check Master, Voice and Music levels separately, and check whether your browser tab is muted.
Returning from another tab may leave the fight paused. Focus the game and press Escape to resume. Check your device output if sound is still missing.

My keys or controller do not respond

Click inside the game, then try the default P1 keys: WASD to move and F for a light punch. Website filters do not change game bindings.
For local Versus, P2 uses arrows and J/K/M/comma. A keyboard may limit simultaneous presses; try fewer keys to isolate the issue.
For a controller, press a physical button after connecting it, then check the in-game Settings mapping. Physical controller compatibility is untested here. Shift+Escape returns focus to the website.

Touch buttons cover the screen

Rotate your phone to landscape and use Fullscreen or Expand view. The game supplies its own touch interface.
Use Exit expanded view to return to the page. Phone browser fullscreen support varies; expanded view remains available.
If a controller and touch buttons conflict, disconnect the controller and tap the game again. This v12.9 behavior has not been verified on physical phones; use desktop keyboard play if it persists.

I cannot join a friend’s room

Online Versus depends on third-party PeerJS signaling and WebRTC connectivity. This site does not operate a matchmaking server.
Check that both players intentionally opened the same hosted v12.9 build and entered the shared room code correctly. Do not put room codes into diagnostics.
Room availability is not guaranteed. If connecting fails, keep single-player Training or Arcade available, or use local Versus on one computer. No random matchmaking has been verified.

I expected a different character or version

This site hosts original v12.9 with 10 fighters. Check the Characters page for the exact roster.
Newer videos or II Turbo may show a different roster. They do not unlock extra characters in this hosted build.
The same fighter cannot occupy a fighter and sidekick slot together. Read Versions before looking for patches; this site provides no unlock download.
