Castlevania: Belmont's Curse on AnyPS5

Verified

• Ubuntu 26.10 / GCC 15.3.0 / RTX 3080 Ti (NVIDIA 615.71.09) / Linux native / SDL audio via PipeWire (discussion #5832, 15–21 Oct 2026): Castlevania: Belmont's Curse PPSA35399 content 01.000.000 on clean AnyPS5 main. Linux in game — main menu, New Game, then the Trevor and Rose boat dialogue. About 3.8 FPS (window title) on main 8f9240f06, GPU about 30% utilized. No local changes and no other pull requests on that first in-game run. Later on clean main b85d972f4: 62–66 presents per 10 s in gameplay (about 1.9× the 32–35 presents per 10 s on eea428ca8). jemalloc 5.3.1 preload on plain main 7e95bde79: 75–81 presents per 10 s. First screen after the logos is black with only the skip prompt; holding Circle (C on a keyboard) skips it. Unmodified main, not a release zip. Single community self-report. In game ≠ Playable.
• Same Linux host and thread: A/B runs of #5404 (draw-cache bypass under 5% hits) and #6539 (relocate across user words that only reach the shader as values) on the boat scene showed no frame-rate gain (discussion #5832).
• Same Linux host and thread: Unity IL2CPP title. Relinked with relinker --registry --module-dir Media/Modules --module-dir Media/Plugins src/eboot.elf app.elf (12 modules, including the 95 MB Il2cppUserAssemblies.prx). Without those module dirs the executable stops at load with Il2cppUserAssemblies.prx: cannot open shared object file. libSceNpCppWebApi.prx is in this dump's sce_module/, so no other dump is needed. .guest.prx files go next to the originals. Run with APS5_HOST_IMPORT_MIB=16384 SDL_AUDIODRIVER=pipewire ./app.elf. --module-dir is a relinker flag, not a game patch.
• Windows 11 Pro 26200 / RTX A2000 Laptop (NVIDIA 610.60) / WinLibs GCC 15.2.0 / Release (discussion #5832 comment, 19 Oct 2026): in game — New Game reaches the boat scene with Trevor and Rose after holding Circle (C on a keyboard) to skip the first cinematic (black screen with the skip prompt), as on Linux. Frame rate very low. The build is not plain main: main from 2026-10-17 plus a Peace Walker test branch, including #6842 (IL2CPP heap hooks) and #7450 (Windows relinker module sharing). #6842 has since merged (19 Oct) and is in v0.1.3; #7450 was closed unmerged. Relinked with relinker --windows --registry --module-dir Media/Modules --module-dir Media/Plugins. Community report in the same thread. In game ≠ Playable.
• Same Windows host and thread: Historical (18 Oct 2026): a Windows 11 Pro run could not load — Failed to load module: ...\libs\Il2cppUserAssemblies.prx, GetLastError: 126. The reporter hit the same error code on libs\libSceNetCtl.prx until MinGW DLLs (libgcc_s_seh-1.dll, libstdc++-6.dll, libwinpthread-1.dll) were copied into libs\. Release archives already include those DLLs. The first Windows comment's path (...\libs\Il2cppUserAssemblies.prx) also suggests a relink without the two --module-dir options.

Blocked

• Speed on the cited Linux main runs (discussion #5832). A 30 s in-game perf profile (18,947 samples) put 83% of samples on the packet-worker thread and 60% of all time inside the AGC driver. The GPU is mostly idle. Later measurements stay CPU-bound even after the about 1.9× present-rate gain on b85d972f4.
• The first cinematic is not drawn: black screen with only the skip prompt. The report says that stop was not investigated.
• Historical (18 Oct 2026): Windows 11 Pro failed to load with GetLastError: 126 (Il2cppUserAssemblies.prx). That load failure is a setup / relink-layout crash from that date, not the cited Windows in-game result.
• Not checked in the cited reports: audio output quality, PSN features, save data beyond the first mount, play past the boat scene, macOS, or AMD/Intel GPUs. In game on the boat scene is not a Playable claim.

Unknown

• Official-table membership. This title is a community report (official: false), not a tested-compatibility table row.
• Whether the current official release zip matches this report.
• Audio output quality. The Linux report used SDL audio via PipeWire and lists audio output quality as not checked.
• Saving beyond the first mount. Discussion #5832 lists save data beyond the first mount as not checked. A later Linux script loads a save for the frame-rate sample; that is not a cited create-and-reload round-trip.
• Network or PSN features. The report lists PSN features as not checked.
• Windows on unmodified current main. The cited Windows in-game used a Peace Walker test branch plus #6842 and #7450. #6842 is now in v0.1.3; #7450 was not merged.
• macOS. No cited macOS session of this title in discussion #5832.
• AMD or Intel GPU in-game reports. The cited Linux host is RTX 3080 Ti; the cited Windows host is RTX A2000 Laptop.
• Play past the boat-scene sample, or completion.

Unknown. Discussion #5832 lists save data beyond the first mount as not checked. A later Linux script loads a save for the frame-rate sample; that is not a cited create-and-reload round-trip.

Game patch

Status: Known

Known. The cited report names Castlevania: Belmont's Curse PPSA35399 content 01.000.000. Unity IL2CPP. Relinked with --registry --module-dir Media/Modules --module-dir Media/Plugins (Windows adds --windows). --module-dir is a relinker flag, not a game patch. No extra title patch file is named as required. Furthest cited in-game used unmodified Linux main 7e95bde79; the first in-game was main 8f9240f06. The Windows in-game used a Peace Walker test branch plus #6842 and #7450.

Network

Status: Unknown

Unknown. Discussion #5832 lists PSN features as not checked. No cited report tests working online or networked play.
