Title

Diablo II: Resurrected (PPSA03912)

Content version tested

01.039.000

AnyPS5 commit

main 19e020a (2026-10-14)

System tested

Ubuntu 26.10, GCC 15.3.0, RTX 3080 Ti (NVIDIA 615.71.09), Linux native

Furthest point

In game

What is shown

Main menu, Offline > New Character, class selection and the Rogue Encampment with the world, HUD and sound. About 4 FPS: two runs standing in the encampment gave 39.9 and 41.1 presents per 10 s with APS5_HOST_IMPORT_MIB=16384 (the default budget is slower). About one launch in five stops at start-up in the title's own code (a null hash-table lookup at app.elf +0x1b997a9, the same with and without the other fixes); launching again gets past it. One earlier run stayed in game for 15 minutes; another crashed once after about 10 minutes in libSceHttp (FindEpoll, from the title's background online code). Online play is not supported (the title reports it failed to authenticate).

Current blocker

Nothing stops it from reaching the game on main: the aborts it used to hit (#1186 depth plane sampling from a later slice, #5779 a storage view from a later slice, #5205 a zero-count indexed draw) are merged. What limits it now is speed: the driver thread is the limit, about 86 us per draw and about 100k draws per 10 s, and the draw cache almost never hits because each draw's user-data words hold per-draw buffer addresses (vertex buffer bases that move by a fixed step per draw, a moving constant pointer). Open PRs #4943 and #5609 address moved pointers and moved base addresses; in a three-run A/B on this title they did not change the speed (data on those PRs).

How it was run

• eboot.bin and sce_module/{libc,libSceJobManager,libSceNpCppWebApi}.prx unwrapped from their SELF containers (the dump is already decrypted).
• relinker --registry src/eboot.elf app.elf
• Copied build/core/libs/libs/.prx to libs/; app0/ has symlinks to the dump plus the converted sce_module/.guest.prx.
• APS5_HOST_IMPORT_MIB=16384 SDL_AUDIODRIVER=pipewire ./app.elf

Update, second round on the same machine (Ubuntu 26.10, RTX 3080 Ti, NVIDIA 615.71.09): the furthest point is now In game. Offline > New Character reaches the Rogue Encampment with the world, HUD and sound working. Built from main of 2026-10-13 plus three local changes; the sceSslSetVerifyCallback stub from my first report is no longer needed because main now exports it.

What was needed on top of main, in the order the title hit it:

1. Main menu abort: sampling the depth planes of depth surface ... (512x512, vk format 124) as a 512x512 texture of guest format 11 (vk 74), dimension 2, 2 slices, levels 0-0, base slice 1 is not implemented (a D16 surface read through an R16_UINT 2D array T# with BASE_ARRAY=1). Same as feat(agc): sample depth plane arrays from a later base slice #1186; I commented there with the data point and a test.
2. Next abort: storage image access to depth/stencil surface ... is not implemented (storage=512x512 guest format=11 mip=0 dimension=2 tile=4 slices=1-1 levels=0-0). A one-slice storage view from slice 1. Related to feat(agc): storage image access to depth planes through 2D array views #5003, which still refuses later slices; I commented there and kept my change on a branch for a follow-up.
3. Abort after Offline > New Character: zero-count indexed draws are unsupported. Fix: fix(agc): skip an indexed draw with no indices or instances #5205.

Performance: very slow with the defaults, about 0.3 FPS in game. With APS5_HOST_IMPORT_MIB=28000 (default 6144) it is about 3.3 FPS in game. Profile at that setting: about 165 ms GPU busy and 133 ms idle per present, and about 7.5 GiB of alias uploads plus 2.5 GiB of direct uploads per 10 s. The cost is memory: the 31 GB machine ran with about 1 GB free and 21 GB of swap in use. The menu runs at about 30 FPS.

Stability: one SIGSEGV in a game worker thread during loading in four runs, not reproduced since.

Update: ran it again on a build of current main (dacd785) plus the open PRs that cover the three aborts, with no local-only changes.

• feat(agc): sample depth plane arrays from a later base slice #1186 (sample depth plane arrays from a later base slice): the "base slice 1 is not implemented" abort.
• fix(agc): skip an indexed draw with no indices or instances #5205 (skip an indexed draw with no indices or instances): the "zero-count indexed draws are unsupported" abort after Offline > New Character.
• feat(agc): storage image access to depth planes through 2D array views #5003 plus a follow-up for views from a later slice (https://github.com/mrfelek/AnyPS5/tree/pr/depth-storage-slice-view-v2): the "storage image access to depth/stencil surface ... slices=1-1" abort.

Result: still In game. Main menu, Offline > New Character, class selection and the Rogue Encampment with HUD and sound all work, and it ran 5+ minutes with no abort. Speed is about 2.5 FPS with APS5_HOST_IMPORT_MIB=28000 (the default budget is slower).
