Crash Twinsanity Improved

A fix-and-polish mod for the PAL release of Crash Twinsanity on PS2 that patches the disc image directly to restore cut content and patch level loading and video output.

My role

Solo project, agent-directed: I chose fixes, specified PAL executable patches, and verified each in PCSX2; agents largely built the patcher and wiki.

What it solves

The retail PAL release disabled the cutscene-skip feature before shipping, loads levels slowly, and outputs 480i, and none of these could be fixed from emulator settings alone.

What it delivers

  • Published a reproducible mod and wiki without distributing copyrighted game files.

Key decisions

  • Patched the executable and ISO, restoring 16 cutscene skips and fixing invincibility masks and crate shadows.
  • Agents built a Python patcher for users’ PAL disc images, plus widescreen/HD PCSX2 presets.

None

Capabilities

  • Direct ISO patching that rebuilds a modded disc image without touching the original
  • Restored cutscene skipping with an on-screen prompt in five languages
  • Keeps defeated bosses harmless and fixes Aku Aku protection around explosive crates
  • Level-loading patch; relative timing varies with CDVD configuration
  • 480p/60Hz output with frame timing matched to the new mode
  • A Python build script and PCSX2 configuration presets

Development workflow

This one was agent-directed from the start. I drove the reverse-engineering - deciding which cut features were worth restoring, reading the PAL executable's behaviour, and testing each patch in PCSX2 - and used agents to write the Python patcher, the build tooling, and the wiki against that spec. The verification is the part I own: every change here was confirmed running on a patched disc image.
