Description

Yoshi's Story displays 'ERR' fullscreen when starting game with Parallel-RDP.
Game responds to input and audio is playing fine, you just can't see anything but 'ERR'.
Game runs fine with Angrylion, and other games run fine with Parallel-RDP.

Video driver: Vulkan
Audio driver: WASAPI and XAudio tested.

Edit: Only seems to occur if Expansion PAK is disabled.

Research direction

Start by reproducing Yoshi's Story with Parallel-RDP and Expansion PAK disabled, using the Vulkan video driver; compare the result with Angrylion and with Expansion PAK enabled. The fix is complete when the game renders normally instead of showing fullscreen “ERR” while input and audio continue to work.
