Some games earn their own troubleshooting page. These three come up constantly — and two of them were named in ePSXe’s own changelogs, which is where this guide starts: with what the emulator team itself fixed, then the settings folklore that actually holds up.
First: be on the current version
Windows v2.0.18 (December 2025) lists compatibility improvements for Valkyrie Profile and a disc-swap fix for Metal Gear Solid: Special Missions, with SPUCORE audio work that touches several era titles. A large share of “unfixable” reports for these games are simply 2.0.5 installs: update from the official package (checksum on our download page) before touching settings. Android users should likewise be on the 2.0.19 series, whose point releases fixed an SPU regression.
Valkyrie Profile
Valkyrie Profile’s historical ePSXe issues cluster around its voice-heavy scenes and battle transitions — audio sync and framebuffer behaviour. On 2.0.18 the game is a named fix, so start from the internal SPU core and a conservative video profile (internal core or OpenGL2 on a moderate preset, framebuffer effects enabled). If voices drift, work the audio fix order rather than stacking plugin tweaks; if the picture glitches at transitions, the framebuffer setting is the usual suspect from our graphics guide. Rip quality matters too: this is a two-disc game, so the matched-set rule from the disc swap guide applies in full.
Metal Gear Solid (and Special Missions)
Two separate concerns. The main game’s famous disc swap is a story moment as much as a technical one — use the proper in-session Change Disc flow at the prompt, never a cold reset. Special Missions (the VR missions disc) had its changedisc behaviour specifically patched in 2.0.18; on 2.0.5 it could demand the main game disc in a loop. Codec-call audio and the Psycho Mantis theatrics are hardware-gimmick moments the emulator handles in its own way — judge them by whether the game continues, not by whether a 1998 controller trick maps literally.
Chrono Cross
Chrono Cross stresses two ePSXe subsystems: its status-screen and menu rendering (a long-standing framebuffer-effects case — keep framebuffer effects enabled and prefer the internal core if menus distort) and its disc boundary, which follows the standard matched-set, save-at-the-boundary discipline. Its large cast of elemental effects also makes it a good stress test after any settings change: if Chrono Cross holds full speed in battle, your configuration is healthy. Element-grid slowdowns that mirror original-hardware behaviour are the game being itself, not an emulator fault.
The general rule behind all three
Named games misbehave for named reasons, and ePSXe’s changelogs are the first place to check whether yours was fixed by the team. Update first, use the internal cores as your baseline, change one setting at a time, and keep your rips above suspicion. Everything else is in the troubleshooting hub.
