Hello
squints long username and welcome to TASVideos.
Be sure to truncate your movie before submitting it in the future as on
first glance it's slower than an existing RTA run.
Light Spike which ends on the final press being an A which reduces this time down by 3 minutes. A better spiking could be done if I checked over it.
Edit: Unfortunately, besides the major issue of using the European version which costs you frames due to language selection (resyncing to the USA version would take time, the adjustment I made immediately dies in the next area) the input could be much more tighter in stages, and you should probably pay attention in the order that you kill the enemies as you can move onto the next screen faster due to it.
Here's my input of just the first section for comparison which is just 85 frames faster (USA version), but it does add up over the ~25 minute TAS.
You may want to have another look over at it again, and take your time, with all the tools available to you in BizHawk and
use the userfiles.
Go again when you've optimized all you can.
And don't do full auto at the end of the first stage, and instead deliberately jump to attack the enemies jumping the vehicles.
