[archanox]

Game or games this happens in

ULUS-10093 WRC

What area of the game / PPSSPP

When loading the game with Dynarec enabled. Even with all JIT functionality disabled.

Original issue #19266

What should happen

The game should load with the JIT backend.

Hm, this problem is slightly different. Does it affect all games?

[archanox]

Yeah all games with Dynarec, and same error with and without everything ticked in the JIT functionality list.

[archanox]

Just tested this recently on a SpacemiT K1/M1, and this issue is not there, but an older JIT issue has reappeared when loading into the race in WRC.

NB, just for future reference this new device advertises rv64imafdcv_sscofpmf_sstc_svpbmt_zicbom_zicboz_zicbop_zihintpause

Whilst the previous sg2042 device supports rv64gc_zfh_xtheadba_xtheadbb_xtheadbs_xtheadcmo_xtheadcondmov_xtheadfmemidx_xtheadfmv_xtheadint_xtheadmac_xtheadmemidx_xtheadmempair_xtheadsync_xtheadvector

I've just now tried the same game, same machine with latest upstream, unfortunately the same issue is there and I'm unable to see any visible errors in the terminal, unless there's a verbosity that needs to be changed?

I still feel the regression happened after the RISC-V JIT was implemented and during the IR JIT for other platforms.

I managed to find the verbose logging output, which yields me this after selecting my vehicle and stage prior to loading into the actual game.

I don't think it's mentioned on this issue, but the game hasn't crashed and is still running with audio etc, just the screen is purely white as shown previously. You can get visibility back when entering the pause menu.
