VICE: attach disk image and run .prg file from OS filesystem
With VICE (2.4.27 on Linux), I'm trying to figure out how to attach a D64 image to drive 8 (with TDE) while running a .prg file from my OS file system.
I've tried a wide variety of command line options, but I either get a message about extra arguments on the command line, or VICE tries to load the .prg file from the attached disk image, which obviously fails as well.
Does anyone know how to do this? I'm trying to keep my assemble-run-debug cycle as fast as possible.

Nice writeup! This is very close to my own workflow.
I have never had a need of adding a delay between doing a reset and loading a new prg into memory. How often does not having a delay cause problems for you? Strange that I haven't seen it if it happens quite often, since I have used it with prg files large and small hundreds of times without any issues.
If you do need a delay, reset with the patched kernal is so fast it would probably be sufficient to do a "sleep 0.1" after (the -q option to nc doesn't seem to allow decimal numbers.) |

Doing a reset and loading a program doesn't cause any problems as long as you don't load and run a BASIC program, or any program that doesn't rely on proper BASIC intialization.
The problem starts with code that relies on BASIC pointers being correct. Even with a patched KERNAL, issuing a 'reset' and a 'load' fails:
When I issue a 'reset 0', the machine calls the reset at $fce2.
Immediately I load my 'foo.prg' program.
Reset is not finished yet, so when it finishes at some point, it invalidates any BASIC pointers you may have set. |

I see. Does it still need to wait anywhere near as long as a second, though? Better safe than sorry I guess, but still. :) |

Well. 1 second is the smallest unit telnet or netcat can handle, which works.
Smaller delays might work, but my experience tells me you're just going to get into more trouble. |

Thank iAN CooG for that, he came up with it. And it does save a lot of time, that little patch ;) |
