Help with MediEvil on OPL

I tried playing MediEvil 2 and the japanese version of ME1 on OPL with Free McBoot, but there are some problems with them, unfortunately.

For ME1(Japan(https://vimm.net/vault/55830)(SCPS-10081)), the opening crawl's narration is silent and the first image of Zarok doesn't show up, and when I start a new game, the game crashes completely. I believe this has something to do with the internal files named "3AV.STR" and "14AV.STR", which have red "X"s next to them when opened in ISO Buster, so someone needs to fix them ASAP.

As for MediEvil 2(SCUS-94564), the screen keeps flickering from normal to blue(that same thing happens to https://vimm.net/vault/52256(SLES-04067)). I can't figure what's causing that problem, but again, someone needs to fix that soon.

Thank you in advance for your help in addressing this problem.
