# Super Mario RPG (`0100BC0018138000`) Update 1.0.1 (v65536) over the base game, SDK 14.3.1. Unity 2021.3.15f1 IL2CPP with CRIWARE on NVN. Modules `main`, `subsdk0` (the SDK's movie library) and `sdk`. Plays on the Mac from a fresh save: the opening movie, the title, a new game with its opening cutscene, the first corridor of Bowser's Keep and the first Terrapin battle. That is a short test: the battle was not finished, and the route ran on the provisional profile, which has the same shaders; the registered profile ran a 60 s boot from a fresh save into the opening movie. No game-specific rewriter cut and no host change of its own. iPhone and iPad validation remains open. ## What it needs | Setting | Where | Why | |---|---|---| | `sys_resource 0x1000000` | [`game.tsv`](game.tsv) | the NPDM's 16 MB of system resource: virtual address memory | | 5 GB guest layout: `mem_reserve 0x140000000`, `mem_alias 0x118000000`, `mem_stack 0x10000000`, `app_pool 0x40000000` | `game.tsv` | [Cult of the Lamb](../01002E7016C46000/README.md#memory)'s layout, the same Unity family; the NSP script's heap check chose the 1 GB pool: the game sets no heap, and with the hardware pool the alias region reached +4.27 of 4.38 GB within its first seconds | | `depth_mode zero` | `game.tsv` | the game calls `nvnDeviceSetDepthMode` with near = 0 (log: `depth mode near=0`), so the pipeline bases made before it runs take the `main0_z` vertex entries | | `shader_groups /Data/=data` | `game.tsv` | everything with shaders is under `Data/`: the player's serialized files and the `StreamingAssets` bundles | ## Frame rate - 60 fps, as the game asks (present interval 1). - **Current, windowless:** left alone in the battle menu, p99 frame intervals of 22.6 to 23.9 ms. Windows holding screenshots, presses and scene changes read up to 95 ms, their long frames with GPU time around 2 ms and most with no new pipelines, on a Mac at load average 19 from other work. The field was not measured without screenshots, nor anything on an idle Mac or with a window, so whether those spikes are all from the shots and the load is open. ## Memory - 4.71 GB resident and 0.89 GB of GPU memory at most over about six minutes, windowless, with a 2.45 GB pipeline archive open; 1.89 GB resident at frame 3300 of the opening movie with an archive of about 120 MB. Six minutes says nothing about growth; a longer soak is open. - The heap check's region check saw alias +2.79 GB in the first 15 s in `nnMain`. ## Files and shaders - The merged RomFS has 1,934 files, 6.35 GB: 1,277 UnityFS bundles and 46 CRI USM movies (1.01 GB). The survey also reports an FMOD marker in `main`. - 82,032 shaders (40,983 vertex, 40,987 pixel, 56 compute, 6 geometry): 82,021 from `Data/` and the player's 11 GLSLC outputs in `main`. All built for the Mac with no failure. It takes about an hour and a half on an M6 on a busy Mac, the longest step of a first build. - `pso_manifest.tsv` has 380 lines (263 shaders, 117 render pipelines): the `pso_user.tsv` of two runs along the route below, not a separate `DM_PSO_RECORD` pass with prewarm off. ## Mac routes - Build with `scripts/build_ipa_from_nsp.py -k --platform mac` and use its printed command. - From a fresh save: the opening movie plays by itself. A skips it to the title, then A on the title and on the menu, A on the difficulty (Normal is selected). The new-game cutscene follows; presses of Plus, A and a held B went to it and it reached Bowser's Keep within about a minute, without showing which of them, if any, skipped it. Press A through the dialogue. - In the corridor, **Up walks up and to the left**. Walking towards the far door pans the camera to the door with Mario out of frame (not a fault: the HUD comes back and he is there once he moves). After the second pan a scene put him back on the carpet and a Terrapin came to life and roamed; touching it starts the battle. In battle A attacks. - From a save on Mushroom Way (`saves/mushroom_way` in the NSP folder, [`smoke.tsv`](smoke.tsv)): A at the title, the menu and the file, and Mario stands on the path with a Goomba just below him. Holding the stick down walks into it, and the battle against three Goombas opens in a sunlit arena; A twice attacks. ## Found on this game - Mushroom Way's battle ground and lower foliage were nearly black, Mario and the UI lit: the baked shadowmask is RGBA4, and its channels read reversed: [RGBA4 textures in Metal's channel order](../../../docs/reference/rendering.md#rgba4-textures-in-metals-channel-order). Checked from a copied save at Mushroom Way: a Goomba battle dark on the host before the fix, lit after it, with an attack played, windowless and muted. - The first NSP script run prebuilt its pipeline archive at the default depth mode: [Offline pipeline archive and profile depth disagree](../../../docs/reference/shaders.md#offline-pipeline-archive-and-profile-depth-disagree). The check boots now set the key. - Calls `nvnCommandBufferSetSubpixelPrecisionBias` and `nvnCommandBufferSetConservativeRasterDilate` repeatedly (thousands of times in six minutes) without turning conservative rasterization on, on the route tested: see [Conservative rasterization remains unimplemented](../../../docs/reference/rendering.md#conservative-rasterization-remains-unimplemented). ## Open - **Current (2026-11-05):** the translator deletes 20 bindless accesses in 4 shaders (4 pixel; texture2D 20), whose results read 0: `0918eb68f1a71924` `220a6f463d1b1588` `768ad53b637e9686` `8027369dadd26a36`. The cause is not traced, and whether a route reaches them is not known. [Losses a shader build reports](../../../docs/reference/shaders.md#losses-a-shader-build-reports). - Everything past the first battle's first attack: the rest of the game, party members, a save and its load. This was a short test on purpose. - Nobody has watched it in motion or listened to it: the checks are single frames and the log. Sound is checked only in the log (one AudioOut with 6 channels; a few underruns of 5 ms, under the load above). Input has gone only through `DM_CTL`, not a controller or the keyboard. - iPhone and iPad runtime validation; no IPA has been built. Memory there is the first thing to watch. - The base game alone was not played or registered; packing it takes a derived profile.
