Spyro 2 PAL crash on loading most of levels (interpreted mode)

[marcovoc]

Describe the bug

crash when launching the demo, or when loading a level other than Glimmer or Summer forest hub in interpreted mode.
The crash talk about "Attempted unaligned JR to 0xXXXXXXXX from 0xXXXXXXXX, firing exception!"
For what i have understand it's related to bad data read from cd. So, when the game start to jump to an adress normally given by sectors loaded from the disc nothing good happend.

I'm currently retro ingenniering the game so if at some point i understand what trigger this crash, i will give more information or even try to fix it.

Expected behavior

Game running correctly and not crash when enter the levels.

Steps to reproduce the bug

1. run the game Spyro 2 PAL
   2a. on the main screen wait until the demo start
   2b. in summer forest enter in a level other than Glimmer.
