Author's comments and explanations:
This is my first PSX-TAS.
I cannot write so many sentences, because I'm very weak in English.

Game objectives

  • Emulator used: PCSX-RR v0.1.2+ svn216
  • CD ID: SCUS-94154
  • Abuses programming errors
  • Aims for fastest time / Any%
  • Genre: Platform

The problems about the sound plugin.

Some sounds are lost in TAS Sound Plugin of Move sync mode. MIDAS PSX SPU does not desync, it may be good. But, they may freeze by a Cortex's voice because reading of the sound is out of condition. It may be necessary you do not use the mode or to change it into other SPU so that you watch the end.

Movement Tricks

Zigzag boost

Crash's speed is boosted, if you continue pressing D-pad diagonally while sliding or jumping.

Slide and Spin of neutral

Sliding speed is kept when Crash spin. But, it becomes low speed if you press D-pad when Crash spin.

About the ice

When you jump from ice, slippery ground is carried over to the moment of the next landing, and it is continued if you jump again. In addition, you can slide at fast speed only once.

Extra Item Glitch

When Crash stamped a box, the counts that stamped an enemy consecutively increase in the same way. And you can get a extra item when this counts exceed 200 times.

0 Nothing
1 One Apple
2 Two Apples
3 Three Apples
4 One Up Panel
5-199 Nothing
200-299 Crystals
300-517 Gems
518-522 Color Gems

Keep the counter

When Crash lands, this counter is initialized, but it is continued if Crash land while spin. And it is continued while Crash slide and squat down.

Spinning stamp

I was able to cancel the bounce of Crash by spinning at the same time to stamp the bounds limit of the box. And it is applied to an enemy.

Sliding stamp

You would stamp it when you jumped as soon as slide attack the enemy.

Detailed commentary

At first 197 times bound. It saves 30 frames about once to hit a head on an object. And, I stamped 17 enemies after having stamped three boxes while letting the counter continue. I was able to continue the counter to the next scene by stepping on the pedestal with spin. However, unfortunately it was not able to continue when a scene was replaced by a fall. Therefore I stamped 8 enemies more in second scene.

I hope you enjoy the run!
