# Remake a 3DS game > A remake rebuilds the code and the assets from scratch while preserving the design. Here is how to scope one and what to keep. - URL: https://www.summerengine.com/remake-a-3ds-game - Keyword: remake a 3ds game - Related: https://www.summerengine.com/porting Remaking a 3DS game means rebuilding a game you own from scratch in Summer Engine, with new code and new assets, while keeping the original design. A remake is not the same as a remaster. A remaster improves the presentation of what exists. A remake replaces the implementation. That distinction sets your whole scope. In a remake, every system gets written again: movement, combat, inventory, save data, menus, and progression. Art is re authored at modern resolution rather than upscaled. Audio is often re recorded or re mixed. What stays fixed is the design: the levels, the pacing, the rules, and the feel. The advantage of a remake over starting fresh is that the hard creative questions are already answered. You know the game works, you know how long it is, and you have tuning numbers that survived real playtesting. That is why remakes ship when original projects stall. ## What a remake keeps and what it replaces Keep the design: level layouts, encounter placement, progression order, story and script, and the numeric tuning that defines how the game feels. Replace the implementation: engine code, asset formats, shaders, interface layout, and anything that talked to 3DS hardware. The line matters because it decides what you argue about. If a system is being rebuilt anyway, rebuilding it better is nearly free. If a level layout is being kept, changing it is a new design task with new playtesting attached. ## Re authoring 240p era assets A 3DS top screen was 400x240. Assets made for it do not have the pixel density for a modern display, and upscaling shows it. In a remake you redraw sprites at the target resolution, rebuild models with higher polygon counts and modern texture maps, and re author interface art as vectors or high resolution bitmaps so it scales. Use the original as the reference silhouette, not as the source image. Keep character proportions and color identity, since that is what players recognise. ## Preserving feel while rewriting the code This is where remakes fail. New code with new physics and a new frame rate produces a game that looks the same and plays wrong. Extract the original constants first: movement speed, acceleration and friction, jump height and gravity, invulnerability windows, animation frame counts, input buffer lengths. Then reproduce them deliberately in the new implementation, including frame rate dependent timings that were written against 30 frames per second. Test against video of the original rather than against memory. ## Scope control and the additions question Every remake faces pressure to add content. New areas, new characters, new systems, a harder difficulty mode. Additions are the main cause of remakes that never ship. A workable rule: finish a playable version that matches the original from start to end, then add. That way you always have a shippable build, and additions are decisions rather than commitments. Quality of life improvements are the cheapest wins, including remapping, faster menus, an autosave, and a modern options screen. ## Rights, licenses, and what you are allowed to remake You can remake a game you created or one you have a written license for. Owning a copy does not grant that. Check work for hire contracts if a studio was involved, and check whether music, fonts, middleware, and third party art were licensed for a single platform, because those licenses rarely extend to a new release. A remake of someone else's title, including anything using Nintendo characters or trademarks, is not something Summer Engine will help you publish. ## FAQ ### What is the difference between a remake and a remaster? A remake rebuilds the code and the assets from scratch while keeping the design. A remaster keeps the original systems and content and improves presentation: resolution, frame rate, textures, audio, and interface scaling. Remakes cost more and change more. ### Can I remake a 3DS game myself? Yes, if you hold the rights. Solo remakes are common, especially for small and medium games. The design work is already done, which is the part that usually takes longest. In Summer Engine you can generate playable scenes from a description of the original and then refine the real project in C++, GDScript, or C#. ### How do I keep a remake feeling like the original? Extract the original constants before you write new code: speeds, acceleration, jump height, gravity, invulnerability windows, animation frame counts, and input buffers. Reproduce them deliberately, adjust for the new frame rate, and compare against recorded video of the original rather than memory. ### Should a remake add new content? Only after the original scope is playable end to end. Additions are the most common reason remakes do not ship. Quality of life changes such as control remapping, faster menus, autosave, and a modern options screen give most of the perceived improvement at a fraction of the cost. ### Can I remake a commercial 3DS game I like? Not without a license from the rights holder. Fan remakes of commercial titles get taken down and can expose you to legal action. Remake your own game, or license one. Summer Engine is for honest rebuilds, not for republishing other people's intellectual property.
