MCP Error message
I'm trying to set up a WinUAE.AIAB setup on my university account, but when it loads into Workbench, I keep getting a error from MCP saying something like:
c:MCP failed returncode 20 Does anyone know what this means? I can't find a reference in the MCP helpfile to any error codes. It's not really a problem, as I can always dive into the startup-sequence and comment the MCP command out, as I don't really need it. (Speed up an emulated amiga? Why?!), it's just a bit irksome, that's all! Thanks in advance for your help! Last edited by AdamSelene; 26 September 2002 at 22:26. |

I tried commenting out the c:MCP command in S:startup-sequence, but then I get some sort of dialogue box asking for a directory T, and thereafter an error like:
echo: unable to open redirection file echo failed returncode 10 Eh?!?!? PS: Have played about a bit more. I had set up three hardfiles to copy the AIAB setup across to. Removing them, and uncommenting the c:MCP command in s:startup-sequence lets it boot up partway now, it gets to showing the workbench bar (the bar at the top of the screen) and a blank background.

Ah. I see. I've been talking bollocks. Activating the Cycle exact CPU and Blitter option is what was causing the MCP error. Don't know why though...

Well, Toni has made a kind of compromise in the past versions with averagely exact blitter emulation, where most programs and games could be run with (except P. P. Hammer, for example!)
Now he's implemented a REALLY cycle-exact blitter emulation, and if you turn it off, the exactness will be *far below* the exactness of the past versions. That's the explanation I could think of. |

andreas: your explanation was perfect!
AdamSelene: Cycle-exact forces 68000 CPU. Don't enable it if you try to emulate higher cpu... |

"Ahhhh! I see," said the blind man to the deaf dog! Cheers Toni! Problem explained, if not solved.
