What is shown

Its start-up screens: the photosensitivity warning, the Ubisoft logo, an intro video, the disclaimer and the autosave notice (screenshots from two runs), then a black screen. It stops 76 to 92 s after start, with its shaders compiled by an earlier run. Frame rate, input and audio were not checked (SDL dummy driver).

Current blocker

Compute shader 0x10b4f58600 reads a 4x multisampled color target as a storage image:

AGC graphics: a storage image access of 0x10e0720000+0x870000 overlaps multisampled color target 0x10e0720000+0x870000 (4 samples), whose samples are only on the host: guest access to it is not implemented

#6973, #6987, #6989, #6995 and #7002 change this path; the title was not run with them.

Needed to get here on main 0d078f7:

• feat(libkernel): accept a kevent read event on descriptor 0 #6343 (merged as 9d4966c on 18 October): without it, the title stops 7 s after start with kevent: EVFILT_READ on a descriptor that is neither a socket nor the read end of a pipe not implemented.
• fix(linux): enter the guest entry on a main stack at the console's address #7532: without it, the title stops with SIGSEGV on the main thread 6 s after start, with nothing in the log. Its allocator looks up a pointer to the main thread's stack, which is on the host stack (0x7fff...).
• fix(agc): decode cube descriptors with slices past their last whole cube #7533: without it, compute shader 0x1000b28c00 stops on a cube texture with seven slices, 120 s after start on a first run: guest cube texture descriptor does not contain a multiple of 6 array slices (format 22, 128x128x7, type 11, tile 9, mips 0..0 of 1) (base array 0).

How it was run

relinker --registry eboot.bin app.elf, with no other options. No environment variables beyond the input file (APS5_PAD_INPUT_FILE).
