Gaseous vs verifydump

Gaseous Server is a free, open-source self-hosted server for managing ROMs and game titles with basic in-browser emulation. It uses multiple sources to identify games and provide metadata. ROM management supports platforms listed by IGDB, while the built-in emulator covers a documented subset including Game Boy, Nintendo 64, PlayStation, Sega Saturn, and Super Nintendo. Installation options include Docker, source, Unraid, and a Windows MSI package. Windows installation is described as experimental. Setup requires MariaDB 11.1.2 or MySQL Server 8+ and FFmpeg; an IGDB API key is optional when using the Hasheous proxy. From version 2.0, authentication includes passwords, two-factor authentication, and OAuth2/OIDC, with Google, Microsoft, and custom OIDC providers documented. The project uses the AGPL-3.0 license and links to Discord for community support. Maintainers recommend avoiding internet exposure when remote access is unnecessary and state that exposure is at the user’s own risk. The free plan is a self-hosted server, so the operator supplies the database and FFmpeg.

verifydump is a free command-line tool for checking compressed .chd and .rvz disc images against Redump Datfiles. It converts each image into the original format described by the Datfile, adjusts the result to Redump conventions, then checks it against the Datfile. Users provide a Datfile, which can be zipped, followed by image files or folders containing them. The tool says it does not modify user files and stops checking an individual image after finding an error. CHD checks require chdman and binmerge, both available in the system PATH; RVZ checks require DolphinTool in the system PATH. Some Redump cue metadata cannot be represented in CHD. Users can provide original cue files with --extra-cue-source or ignore cue mismatches with --allow-cue-file-mismatches. Verification creates temporary converted files and deletes them afterward; the project suggests a RAM drive for frequent checks or large collections to reduce SSD writes. Windows users can use the offered executable, while Linux and macOS users can install through pipx or another Python package installation method. The package requires Python 3.10 or later and below 3.16. The project directs bug reports and questions to GitHub issues.
