I manage to compile the project and got the .cue and .bin files.

When i used ePSXe205 at first and it gives me black screen. Nothing happends.

Then i tried it with duckstation and with the Fast boot option I manage to get the game work.
If i run with duckstation with Default/Full boot i gain the same issue and the game wont start.

I wonder how this can happend and maybe you have a answer for it?

PS: the compiled horror.exe works on duckstation and doesn't work on ePSXe205.

I looked over the code and tried a couple things to fix the weird sound issue you're having (weird frequencies instead of foot steps are played).

I couldn't fix the issue, but I've made a few interesting discoveries (Void Linux, x64, using the Mednaffe emulator):

Scenario 1

You don't play any sound in gameInit():

//int ch = play_sample(steps_addr, steps_sr);

This leads to the following:

• A weird cracking sound is being played at the start.
• The yay sound becomes the steps sound.
• Whenever you catch a ghost, steps is played (without any reverb). And it's played correct. No weird frequencies whatsoever
• But: no actual foot step sounds while walking, though.

Scenario 2

You play yay in gameInit():

int ch = play_sample(yay_addr, yay_sr); // after yay has been initialized

This leads to the following:

• A weird cracking sound is being played at the start instead of yay.
• The foot steps are actually playing while walking!
• But: they're played only once and you have to stop and start moving to hear them again (which is probably a completely different issue I guess).
• Also: A different kind of weird (and high) frequencies are played seemingly randomly OR after a specific/random amount time during which no other sound is playing (maybe even only after playing steps at least once, don't know for sure).
• Also: Same as Scenario 1, steps is played whenever you catch a ghost without any reverb.

Scenario 3

You play victory in gameInit():

int ch = play_sample(victory_addr, victory_sr); // after victory has been initialized

This leads to Scenario 2 again.

Conclusion

My guess is that either your mechanism for loading the sounds (VAG_Header struct + upload_sample()) or your mechanism for playing the sounds is not implemented as it should be. I'll test more and keep this issue updated when I can.
