coding issue

[chrono trigger]

ok so im a little confussed when i had my psp phat this code i wrote worked on lua player fine, but then i bought a psp slim and had to find a different lua player that worked for it and im now using lua player HM v1.0 but when i tried to load my code it just gave me a black screen and shut off so do you think it is a prob with my code something possibly getting changed? or do you think its a combatibility issue?
p.s. heres my code if someone would be nice enough to read through it to see if its the thing causing the problem. (and its not the prettiest written code just so you all know)

Thank you to anyone that is willing to help
p.s. if this is the wrong place to post this im sorry

I'm pretty sure it's gotta do with compatibility. Or that might be wrong, since the last time I did coding was quite a while ago. Forgot pretty much everything. I don't know how to do it so it'd work on a Slim though :/

But I do know, that for eboots you need to compile it with a 3.8+ Kernel or something. Check out the coding website

That was the forum I used when I was learning. Perhaps they can help you .. but the forum is kinda half dead.
