Spyro 3 anti-tamper measures still active #98

tonyhax version: 1.6.3
Game name: Spyro: Year of the Dragon (Rev 1)
Game code: SCUS-94467
Executable hash: MD5: b02967f6f30d07ce9a68500e36cb299b
Triggered at: While most anti-tamper measures seem defeated (no disappearing eggs, no hacked game warning from Zoe, no Sheila reset etc), upon entering world 2, gems (small amounts) start to disappear from levels. This is proven by activating the Sparx treasure finder in levels with the missing gems; Sparx doesn't point to any gems anywhere in the level or any of the sub-areas -- the gems have simply been deleted from the game (which is one of the many anti-tamper effects). Additional testing with SpyroEdit's gem attraction feature on my save file also suggests that these gems do not exist anywhere in the levels anymore, rendering 100% completion impossible.
Is it an original disc or a burned copy?: Burned copy

Here is my save file if you would like to verify that the gems are completely missing: https://drive.google.com/file/d/1drk6pLmusY5WqjCHfsNn7DozxklFsiEg/view?usp=sharing

However, I believe the damage is done and I will most likely have to start the game over.
