[PS1] Einhaender (Japan): Graphics randomly corrupt towards the end of stage 1

[HeroponRikiBestest]

The graphics corrupt towards the end of stage 1, seemingly at random. The first time, I had died 3 times to the boss before it happened. The second time, I hadn't even reached the boss yet.

Ares v128 compiled on 5/27/2022
Linux Mint 20.2

When first booting the game, the log outputs:

The first part of the log output when you boot the game is now gone, and the output when the corruption happens is shorter. Said corruption still happens, though.
