GTA Vice City browser: files, storage and check limits

What the project documents

The README identifies a WASM port based on reVC. It describes importing game.tar.gz into browser-local OPFS storage and using a service worker to read it. Offline use and save handling are author-documented features; we have not tested them with game data.

Prepare data before opening the project

Use data from your own legitimate copy, but do not assume that compressing an installed game folder produces the required archive. The reviewed loader checks for prepared engine and data files, including vcbr/vc-sky-en-v6.data, vcbr/vc-sky-en-v6.wasm and vcsky/sha256sums.txt.

The extraction code preserves archive paths. A containing folder around those directories will not match the loader’s expected paths. This is a source-code finding, not a tested conversion recipe: the reviewed material does not explain how to create all required files from a supported retail release.

The observed import flow

The author documents this import sequence for an already compatible archive. We have observed the file selector, but have not completed import or gameplay with user-owned data.

Confirm how your legitimately held data becomes the prepared archive required by this exact build. If that step is unresolved, stop here; renaming a ZIP file is not conversion.
On the external project page, use Select game.tar.gz and select the compatible archive on your device.
Wait for extraction and verification. The current code checks required paths before enabling Start; extraction reaching 100% alone is not a successful readiness check.
Use Start only after the project reports readiness. Record any missing-file or storage error if verification fails.

Saves, controls and storage

The author describes importing and exporting PC saves, and warns that resetting data removes saves and skins. Keep your own backups before changing browser storage. The game’s controls, saved-game restoration and offline restart still need an actual session test; no guessed key bindings are supplied here.

Questions before you start

Does the engine include Vice City?

The project disclaimer says game data is not included and asks for a legitimate copy. This directory supplies neither the game nor a download of its files.

Does it work offline or on a phone?

The author documents offline behavior and touch controls. We have only reviewed the source and import screen, so these are not verified compatibility claims.
