Problem starting external PSX-EXE

[Dedok179]

Hello. Please help me solve the problem. An external executable file cannot be executed when the code for switching to the asm routine is active, but it executes fine when it is loaded into memory from the inside of the main executable file or when switching to the asm routine is disabled. What could be the problem and how to solve it?

Try doing it with interrupts disabled by using 'EnterCriticalSection' and then turn them back on with 'ExitCriticalSection'.

No, this did not fix the problem.

Something is getting trashed in memory then. You'll have to do some more debugging and tests. One thing you can check is to compare the registers on the one that works and the one that does not to make sure that something like RA (for example) isn't pointing to something different.

Well, I don’t see any serious differences here.

Maybe after switching to copying the asm routine I need to give CD some command? It just all works perfectly when the executable file is loaded from the internal file when everything is written to an empty disk, or how then can I do it to load the file from the internal storage and force the rest of the data to be picked up from the disk?

Everything turned out, it was necessary to copy the trainer files through the asm function).

That's cool that you solved your problem. I have a question though. What flags do you set in your function setflags() before you jump to game. I'm interested in knowing... It might solve a problem I'm having. Thank you.

I don't use her anymore. Now the structure looks like this, and everything works fine on the console.
