FCEUX vs OpenInvoice

FCEUX is a free, open-source emulator for NES, Famicom, Famicom Disk System, and Dendy systems. It supports NTSC, PAL, and NTSC-PAL Hybrid video modes and offers tools for casual play as well as advanced work such as debugging, ROM hacking, map making, tool-assisted movies, and Lua scripting. The project maintains Win32 and Qt/SDL ports. The Qt/SDL version runs across Windows and UNIX-like systems, including Linux, Solaris, BSD, and OSX. Its tools include debug utilities, movie recording, a TAS Editor, sprite viewer, NES Palette Editor, AVI RIFF Tree viewer, and frame timing tool. Network play in both Win32 and SDL ports is not functional, and the project says it has no plans to fix it. Building Qt/SDL requires Qt5, SDL2, minizip, zlib, and OpenGL; CMake is needed to build from source. FFmpeg libraries are optional for AVI recording, and libx264 is optional for H.264 AVI encoding. The project dates to 2006, and its home page lists version 2.6.6, released on 26 August 2023, as the latest release.

OpenInvoice extracts structured information from PDF and image invoices, then lets users check the results against the source document, correct fields, and export CSV or JSON. It identifies supplier and client details, invoice number, date, totals, tax, currency, SIRET, VAT number, client number, and line items. Processing starts with regular-expression patterns and invoice2data templates, using a MiniMax M2.7 language model only when required fields remain missing. The project lists English, French, German, and Swiss formats and more than 190 vendor templates. Its dashboard tracks processing volume, success rates, supplier distribution, and language-model costs. The API covers extraction, webhook ingestion, document management, CSV export, dashboard statistics, and quality metrics. Typical connections include Microsoft Teams, Outlook or email through Power Automate, OneDrive or SharePoint, and webhooks. OpenInvoice can run on customer infrastructure and connect to ERP, accounting, Microsoft 365, and email systems. The code is free and open source; deployment, integration, and ongoing support are paid services.
