I lost the source code. Can you still help?

Yes. We specialize in decompilation and reverse-engineering. We can often recover assets and logic directly from the retail build (APK/EXE/SWF) to reconstruct the project.

How much does a port cost?

Flash-to-HTML5 conversions typically range from £5,000 to £20,000 depending on complexity. Full engine migrations (e.g., Old Unity to New Unity) require a custom audit.

Can you update a game if we have lost the original source code?

In many cases, yes. We specialize in reverse engineering. We can often decompile existing builds to recover assets (art, sound, models) and reconstruct the game logic in a modern engine like Unity. While having the source code is faster, it is not always mandatory for us to rebuild your game.

Do you handle Flash-to-HTML5 or Flash-to-Unity conversions?

Yes, this is a core service we offer (see our work on the Great Fire of London). We port end-of-life Flash games to modern standards (HTML5/WebGL or Unity) so they remain playable in modern browsers and on mobile devices without requiring plugins.

My game was removed from the App Store/Play Store. Can you fix it?

Absolutely. Games are often delisted for failing to meet new requirements, such as 64-bit compliance, API level updates, or privacy rules (GDPR/ATT). We can update your codebase to meet the latest Apple and Google certification standards and get your game back on the store.

Can you upgrade an old Unity project (e.g., Unity 5) to the latest version?

Yes. Upgrading across major Unity versions often breaks physics, lighting, and custom scripts. We have a systematic process for jumping versions, fixing obsolete APIs, and replacing deprecated packages to bring your project onto a stable, modern Long Term Support (LTS) version.

Will the game feel different after modernization?

Our goal is usually to preserve the game feel 1:1. However, we often modernize the User Experience (UX). This includes updating UI for modern aspect ratios (removing black bars), adding support for touchscreens, and implementing accessibility features that weren't standard when the game was first released.

Legacy Game Modernization

Breathing New Life Into Classic Games

Flash is dead. Old Unity versions break. App stores delist non-compliant builds. If your classic game is stuck on an obsolete platform, we can bring it back to life. We specialise in rescuing legacy titles — including cases where the original source code has been lost. Our team brings specialist preservation experience, including work on the Museum of London’s Great Fire of London Flash-to-HTML5 conversion. We preserve the gameplay your audience loves while modernising everything underneath.

Our Game Preservation & Upgrade Workflow

Modernizing a legacy game is like restoring a classic car. We carefully dismantle the old build, salvage the core components, and rebuild them on a modern engine chassis that can run for another decade.

1. Forensic Audit & Recovery

If the source code is lost, we start with “Digital Archaeology.” We use advanced decompilation tools to extract assets and logic directly from the final build (SWF, APK, or EXE).

Decompilation: Using tools like ILSpy or DnSpy to view the original logic inside compiled binaries.
Asset Extraction: Recovering original sprites, audio files, and data tables that are locked inside old formats.
Feasibility Report: We deliver a roadmap detailing exactly what can be saved and what needs to be rewritten.

2. Engine Reconstruction

We port the logic into a Long-Term Support (LTS) version of Unity. We don’t just wrap the old game; we rebuild the architecture to ensure stability.

Logic Porting: Translating ActionScript (Flash) or legacy C++ into clean, modern C# scripts.
Bug Fixes: Squashing the decades-old bugs that plagued the original release.
Performance Tuning: Optimising the code so the game runs at a smooth 60 FPS on mobile devices, not just high-end PCs.

3. Asset Upscaling & Restoration

Old games often look blurry on modern 4K screens. We enhance the visuals without losing the nostalgic charm.

AI Upscaling: Using neural networks to sharpen low-resolution textures and backgrounds.
Vectorisation: Converting Flash vector art into crisp SVG or Unity sprites that scale infinitely.
UI Redesign: Rebuilding menus to support wide-screen aspect ratios (16:9 or 19.5:9) instead of the old 4:3 box.

4. Modern Compliance & Deployment

The final step is ensuring the game survives the modern app store ecosystem.

Input Modernisation: Adding touch-screen gestures, virtual joysticks, or controller support to mouse-only games.
Safe Area Implementation: Ensuring UI elements don’t get hidden behind the “Notch” or “Dynamic Island” on modern phones.
64-Bit Compliance: Delivering the mandatory technical updates required by Google Play and the Apple App Store to prevent delisting.

Don’t let your classic game die. We’ll bring it back to life on modern platforms.
