Title

FFTARecomp (PPSA98512)

Content version tested

ps5-v1.0.0 from the homebrew catalog (darkxex/FFTARecomp-PS5, release zip PPSA98512.zip, 17 MiB). It is the Final Fantasy Tactics Advance recompilation; it needs the user's own cartridge dump in /data/FFTARecomp, which I don't have, so the furthest it can go here is its "no cartridge" screen.

AnyPS5 commit

main a6dcea9 with the libScePosixForWebKit export of #8080 on top (I had the same one-line forward locally). Last updated 2026-10-22.

System tested

Ubuntu 24.04 x86-64 container under Rosetta on an Apple M5 (macOS 26.2), GCC 13.3, Release, llvmpipe (Mesa, LLVM 20.1.2), no real GPU.

Furthest point

• Does not convert
• Stops before the first frame
• Logos or loading screen
• Menu
• In game

What is shown

Nothing is presented yet. With #8080's export the title starts: it creates its Vulkan device and a 3840x2160 swapchain, opens /data/FFTARecomp/logs/FFTARecomp.log, logs no cartridge found in /data/FFTARecomp: waiting for one and pad 1: Player (17 buttons, 6 axes), and records its first three draws (the "need cartridge" screen, judging by assets/need-rom.rgba in the package). Each draw takes about 360 ms on llvmpipe, and about 10 s in, llvmpipe aborts the process:

[debug:0] LLVM ERROR: Cannot emit physreg copy instruction

That is inside Mesa's LLVM backend, not the emulator, so a real GPU is the next step; no frame was dumped before it.

Current blocker

On plain main the loader stops before anything runs, on the one export the title imports from libScePosixForWebKit that the module does not have:

./app.elf: symbol lookup error: ./app.elf: undefined symbol: cB4rMoKU4UI

cB4rMoKU4UI is pthread_setname_np; open #8080 adds it. After that, on llvmpipe, the stop is the LLVM abort above.

The title also imports shm_open, readlink, cpuset_getaffinity, _umtx_op and sceSystemServiceLoadExec, which have throwing paths; none was reached in this run.

How it was run

relinker --to-rosetta --registry src/eboot.elf app.elf with the package's sce_module/libc.prx beside the eboot, the package contents as app0/, then

SDL_VIDEODRIVER=x11 SDL_AUDIODRIVER=dummy GALLIUM_OVERRIDE_CPU_CAPS=avx xvfb-run -a -s "-screen 0 1920x1080x24" setarch x86_64 -R timeout 150 /lib64/ld-linux-x86-64.so.2 ./app.elf

(ld-linux because Rosetta's ELF loader refuses the converted binary's first PT_LOAD). The package's lapy.elf and lapy-manifest.json are the jailbreak-side helper and are not used.
