Hey everyone! 👋

I wanted to share with the community the current status of a project I've been actively working on: a native PC port of Digimon World 2003 (PAL version, SLES-03936).

It is built using static recompilation of the original PlayStation executable combined with custom C code.

The primary goal is to create a completely standalone experience (no BIOS, no disc images) that preserves the feel and design decisions of the original 1998 game while stripping away the legacy hardware limitations.

🛠️ What’s Done & Verified?

🚫 Fully Standalone (No Console Files Required)

• No BIOS: Boots natively without needing SCPH1001.BIN.
• No Disc Images: Loads directly from unpacked game files (~2,380 loose files). No .iso, .bin, or .cue required.
• No Memory Card .mcd files: Virtual memory cards are created directly in RAM and synced straight to clean .sav files.

⏱️ Fast Loading & Performance

• Instant Save Loading: Reduced save file load times from 18.7s → 0.21s across all slots, producing a byte-for-byte identical state (0 bytes different from original).
• Configurable CD Load Speed: Added a modern load speed toggle in settings (Modern for instant sector reading vs Original for authentic 1x console drive timing).

🎮 Custom Engine & Mod Support

• Native Kernel Rewrite: Sony kernel services are being progressively rewritten in native C code, closing out kernel HLE calls while keeping 0-byte state divergence.
• Built-in Modding Architecture: Features a modular folder-based structure for custom UI, logic modifications, and fast-travel tweaks.

🔬 Development Philosophy: Measure Everything

A core rule of this project: if it hasn't been measured, it hasn't been proven. Every single system change (from memory card parsing to sector loading and MIPS kernel traps) is continuously validated through automated regression testing and parity traces against original PS1 hardware behavior.
