Dekadence loader & disc side change (1541u)
Hey everyone,
Siesta is working on a new demo for X2016, and the side A is 100% finished except that we're having trouble mounting side B with 1541u. Adder, our coder, is using the Dekadence Loader
What's the common protocol for these automatic disc side detects with 1541u?
We've been out for 20 years so please teach us.. |

all common methods should work, if not - contact gideon so he can fix the damn thing =)
a common fault however is to check the (real) disk id for disk changes - that will fail if the ID in the directory is the same on both sides (because emulators, and 1541u, reuse that id for the disk-id when using d64s) |

yes we are doing a demo to release at x-2016.
we use for side a a loader called Dekadence from SounDemoN.
the problem that the program has is the flip disc via *mount* on ultimate 2.
if we mount a disc ..after that the loader isnt useable.
so a reset of floppy is needed for using the init-routine of Dekadence again .. because we can only one time install the Dekadenz.
what can we do |

I can prove that it is not on the id's.
when i try to mount floppy 2 times it doesn't make a difference. |

one big tip, make sure side 2 also has a bootfile, so the demo can be started there as well in case the flipdisk fails. |

also keep in mind that disk changing via the menu _IS_ prone to errors and will randomly fail (or not so randomly if you are for example using some timer-irq driven stuff in the turn disk part).
first of all make sure it works on a real drive - if it then doesnt work on 1541u, most likely its not your fault. |

@Burglar
we have a .d64 with running file
@Groepaz
i believe that the demo runs on real disk..
there is a flip disc and the loader doesn't changes |

@Burglar.. we played with the idea to make side 2 runnable.. it will be so
Thanks for that info .. may it helps at the competition too |

Afaik the dkd loader does not have a flip disk detection. It does not have special command for reloading the directory, but there is a reset command, if I recall it correctly.
Loader was used for example in Vicious Sid demo. The turn disk part asks to flip disk and press space and then it starts from side 2. |
