Ico (SCES-50760 | 5C991F4E): Incorrect "60 FPS & No Interlacing" patch breaks cutscenes

[Lu1zLuna]

Description

In Ico (SCES-50760 PAL), the “60 FPS & No Interlacing” patch included with PCSX2 is incorrect and does not match the original implementation by the patch author, Red-tv (link to his post).

When enabled, the patch causes in-game cutscenes to run at 60 FPS, which completely breaks their timing and animations. Additionally, the no-interlacing hack does not appear to function correctly, resulting in visible interlacing artifacts and flickering during cutscenes.

Expected behavior

• Gameplay runs at 60 FPS
• In-game cutscenes revert to 30 FPS, preserving correct animation timing
• Proper deinterlacing, with no flickering or interlacing artifacts

Actual behavior

• Cutscenes run at 60 FPS
• Cutscene animations play at incorrect speed (double-speed behavior)
• Audio desync
• No-interlacing hack is not applied, causing Interlacing and flickering

Steps to reproduce

1. Enable "60 FPS & No Interlacing" patch in Ico SCES-50760
2. Watch the intro or start a new game and watch the first cutscenes.
