Can anyone help me with this error message?

EPSX: Opcode [13-4f44213c] in PC [bfc00000] not implemented [00000000:000:0]

Hey, when and if someone knows the answer they will post. There's no reason to repeat yourself
You'll probably have to wait a while for this answer because its not a common problem. Just be a little patient.

I'm no emu coder, but here goes....

That message, in (almost) plain English, means that the instruction/operation [13-4f44213c] found in PC (program counter? maybe..) [bfc00000] is not implemented in the emulator.

The basic idea of how an emulator works is to 'map' processor instructions (in this case, one from a PSX) to another processor instructions (to your PC)... ok some people will shoot me for saying this (because there's "high-level emulation"), but this is the basic idea, I don't want to go to more details, 'cuz I don't know a lot about that

Anyways, the error pops up because the game you are trying uses this operation/instruction that does not have a 'mapping' in ePSXe yet... which means you're out of luck. Try a different emu, or wait for the next version.

I *think* that's what it is, but I'm sure the emu authors and plugin authors will be able to give you more detailed (and accurate) answers, should you want more.

I only posted it here because sometimes people don't pay attention when you post at the end of another thread. But anyway, I think the first half has to do with the bios because it changes when I change Bios. I've also tried various games. I'm trying to get the internal CD player to work and am getting the same message.

I'd just forget about the internal CD player. It isn't perfect(obviously) and it doesn't do anything that other cdplayers don't do besides that nifty screen, but if you still want to use it then read this thread.

 

[Sonic98]

I just want to use it to see if any CD works audio or pSx

 

[Sonic98]

I tried everything in the other thread and still nothing. Argggggggggh I can't get anything to work with this program. PSX or Audio CD's. I'm about to break something. Dang, I can't even get the stuip wizard guide to work right. I guess when my partner brings Tekken 3 by today, since it's supposed to be a game that definitely works, I will see if this program works for me at all.

 

[kairi00]

Trust me, Audio CD is not the best way to see whether your playstation emulator is working or not....

 

[Sonic98]

well the fact that it's telling me that the bios in not implemented and the bios files don't show up when I run the wizard guide makes me think I have a bad copy of the bios. I need I did get both copies from the same site. Because that first part of the error message does change depending in which bios I am running.

 

[Sonic98]

I am so mad and happy at the same time right now because I was right!!!!!!!! I did have a faulty copy of the bios. I just went and download scph1001.bin from another site, and it was 3 times as large a file as the copy I already had. Now I just need to find a decent copy of scph7502.bin

 

[Adair]

Don't worry about scph7502. its not going to be any better than what you've got.
So did the wizard guide work? and Tekken3?

 

[Sonic98]

Well I only want to have 7502 incase something happens to the one I have. Yes, now the wizard guide works. I have not tried Tekken 3 yet. I was not able to borrow the CD from anyone yet. My cousin doesn't want to give me the CD when he is not at home. I guess he is scared I will practice. I wish I had a CD burner; I'd make an ISO.

 

[Jau]

you don't need a cd burner to make an iso incase you didn't know that.. just use cdrwin to create the iso for you.

 

[Sonic98]

Yeah I did know that. I think I was going crazy because I was thinking that CD-R's didn't have as much capacity as a PSX CD. I don't know why I was thinking that. I was gonna put my ISO back onto a CD for back-up purposes. That why mentioned the burner.

 

[Adair]

Quite often you'll find that an ISO of a PSX CD is 700+Mb even though a PSX CD only holds 650Mb. This is because windows adds some stuff to it. I forget what it adds, but anyway it won't effect your ability to copy an ISO on a 650Mb CDR(if you ever get a CDR drive).
