Console Porting Services

Sony dev kit access and PlayStation Partners programme membership. We integrate DualSense features: adaptive triggers that provide resistance feedback, haptic feedback for environmental texture, speaker output for directional audio cues, and lightbar colour tied to gameplay state. PlayStation Network integration covers trophies, Activities (PS5 quick-launch cards), friends lists, and voice chat. We manage the full TRC (Technical Requirements Checklist) compliance process and handle submission through the PlayStation Partners portal. For games targeting both generations, we build PS4/PS5 cross-generation packages with appropriate quality scaling.

Microsoft dev kit access and ID@Xbox programme membership. Xbox Live integration covers achievements, Game Pass readiness (ensuring your game works within the Game Pass ecosystem including cloud gaming), and Quick Resume support so players return to exactly where they left off. Smart Delivery ensures a single package serves optimised builds to each console SKU: Xbox One, Series S (targeting 1080p/1440p), and Series X (targeting 4K). We manage XR (Xbox Requirements) compliance and handle certification submission. Xbox Accessibility Guidelines (XAG) compliance is increasingly enforced, and we build for it from the start.

Nintendo dev kit access and Nintendo Developer Portal membership. Switch is the most technically demanding console port target due to its mobile-class Tegra hardware, which is significantly more constrained than PS5 or Xbox Series X in CPU, GPU, and memory. We handle handheld/docked mode transitions with dynamic resolution scaling and performance profile switching. Joy-Con support covers detached mode, motion controls, HD Rumble, and touch screen input in handheld mode. Nintendo Account and online service integration is implemented to specification. Lotcheck compliance is Nintendo's certification process, and we manage the full submission cycle including addressing feedback rounds.

While not a traditional console, Steam Deck has become a significant platform target with its own compatibility requirements. We test for Verified/Playable compatibility, implement controller-first UI and input handling (the Deck uses gamepad controls by default), ensure correct suspend/resume behaviour, and set performance targets appropriate for the Deck's APU. For many games, Steam Deck compatibility comes nearly free if the PC version already supports controller input, but games with mouse-dependent UI or high system requirements need targeted optimisation.

Codebase review to identify platform-specific dependencies and blockers. Middleware and plugin compatibility check against the target console's supported libraries. Performance profiling to estimate the optimisation gap between your current build and the target hardware's capabilities. Certification requirements audit against your current implementation. Deliverable: A feasibility report with effort estimate, timeline, and risk register. This is a standalone deliverable. You can use it to budget the port or to brief another team if you prefer. Start with our free Porting Feasibility Checker for an initial assessment before the detailed audit.

Dev kit setup and build pipeline configuration for your target platforms. Platform SDK integration: PSN, Xbox Live, or Nintendo Online depending on target. Achievement and trophy implementation with correct descriptions, icons, and unlock logic. Save data management using each platform's cloud save APIs. Controller input mapping with platform-specific features (DualSense haptics, Joy-Con motion, Quick Resume state).

Performance profiling on actual target hardware, not estimates. GPU optimisation: draw call reduction, shader simplification, dynamic resolution scaling. Memory optimisation to fit within platform memory budgets (Switch is the most constrained at around 3.2GB available to games). Loading time optimisation to meet platform-specific maximum load time requirements. Thermal and power management, particularly for Switch in handheld mode where the SoC throttles under sustained load. Our Performance Optimisation service covers the technical approach in detail.

Full compliance pass against TRC (PlayStation), XR (Xbox), or Lotcheck (Nintendo). System event handling: controller disconnect, headset plug/unplug, overlay activation, suspend/resume, and low battery warnings. Accessibility feature implementation as required by each platform. Certification submission through the platform's developer portal, and managing feedback rounds until the build passes. Our console porting checklist blog post covers the most common certification failure points. Verify your readiness with our Platform Readiness Checklist.

Certification testers will pull the power cable mid-save. Your save system must handle this gracefully with atomic writes or backup saves. A corrupted save file that prevents the game from loading is an automatic certification failure. We implement save systems with write-verify-commit patterns and automatic backup rotation.

The game must pause and display a reconnection prompt when a controller disconnects, then resume correctly when it reconnects. This must work during cutscenes, loading screens, and multiplayer sessions. Headset plug/unplug must route audio correctly without interrupting gameplay. These edge cases account for a significant proportion of first-submission failures.

Certification testers will leave the game running for hours, navigating menus, loading and unloading levels repeatedly. Any memory growth that eventually causes a crash or performance degradation is a failure. Switch is the most sensitive to this due to its limited memory budget. We profile memory allocation patterns during soak testing before submission.

Trophy and achievement descriptions, icons, and unlock conditions must meet strict platform formatting guidelines. Trophies must unlock reliably under all conditions and must sync correctly with the platform's achievement service. Secret trophies must be correctly hidden. These seem like minor issues but are common certification blockers.

Each platform specifies maximum acceptable loading times. Exceeding them is an automatic failure, even if the game runs perfectly otherwise. Accessibility requirements are increasingly enforced: subtitle options, control remapping, and colour-blind support. Microsoft's Xbox Accessibility Guidelines (XAG) are the most detailed, but Sony and Nintendo are moving in the same direction.

Simultaneous multi-platform development builds all console versions in parallel from a shared codebase. Sequential porting develops for one lead platform first, then ports to others. Simultaneous is faster to market across all platforms but requires more upfront architecture planning. Sequential lets you learn from the first port and apply those lessons to subsequent platforms, often reducing total effort.

The lead platform should typically be the most constrained target. If Switch is in your target list, developing on Switch first means the PS5 and Xbox versions will comfortably exceed performance targets rather than requiring painful optimisation downward. If Switch is not in scope, the choice between PlayStation and Xbox as lead depends on your target audience, certification timeline, and any platform exclusivity agreements.

Platform-specific code (SDK integration, input handling, save data, certification requirements) is abstracted behind interfaces so the majority of the codebase remains platform-agnostic. This minimises the amount of code that needs to be maintained separately per platform and reduces the risk of platform-specific regressions when the shared codebase is updated.

Stagger submissions to avoid bottlenecking QA across three platforms simultaneously. Each certification round takes 1 to 3 weeks, and failure means a resubmission cycle. If you submit to all three platforms in the same week and receive feedback from all three simultaneously, your team will be context-switching between three different certification fix lists. Staggered submission (2 to 3 weeks apart) is usually more efficient. For multi-platform projects that also include mobile, see our Mobile Development service.

Domi Online is a multi-platform Unity MMORPG with server-authoritative networking architecture. The performance optimisation work (draw call reduction, memory management for 1,000+ concurrent players, network bandwidth optimisation) directly translates to the challenges of meeting console certification requirements. Server-authoritative architecture is also a requirement for online games on console platforms.

Our founder David's experience at Jagex included contributing to RuneScape's expansion across multiple platforms, including the challenges of bringing a complex PC game to different input paradigms and certification requirements. RuneScape's cross-platform architecture, serving the same game world to PC, mobile, and console clients simultaneously, required exactly the kind of platform abstraction and performance scaling that console porting demands. Read more about cross-platform porting challenges in our RuneScape porting blog post.

Empires Rise is a 4X strategy game where the performance optimisation work (procedural generation within memory budgets, draw call reduction for complex maps, chunk-based loading) mirrors the exact challenges of fitting a game within Switch's hardware constraints. The 4X strategy genre has a strong console audience, and the engineering foundations are console-ready. Further reading: Is Your Game Ready to Port? and Platform Readiness Before Launch.
