Quoting MagerValpI'm absolutely floored, congrats on shipping! I remember us chatting about it 10 years ago, it's amazing that you figured everything out. Thanks! Has it been that long ago already? =) But yeah, i've had a draft in some text file for years, and "due to the current situation" (R)(TM) starting around March this year, i decided to type the stuff into an actual assembly source code. Turned out i had to come up with a few more tricks than envisioned initially, but.. yeah. Worked out fine in the end. :) |

Thank you for this incredible feat.
Do you think it can be ported to the VIC-20 ?
Can it be done with the VIAs ? |

Corner case report--
Hardware: Ultimate 64 running firmware v1.28 / 3.7
NTSC mode
Internally emulated 1541
Transwarp Game disk C
With stock ROMs:
Loading Spike behaves as intended.
With JiffyDOS:
When Spike finishes loading and the ding plays, although the speedometer feedback flashes briefly, the screen clears and goes to a READY. prompt top of screen (as though one has hit RS+RESTORE, etc.)
Spike does RUN just fine, however.
I can replicate this behavior on a cold start.
Can provide a documentary video on request. |

Can it be done with the VIAs ? Might be possible. But then it's only sensible for expanded VIC-20, no? The 3.5 KB of the stock machine are filled quite swiftly with Soundemon's loader. =) |

(Additional detail: the load works as intended with Jiffy enabled if I naively use LOAD"*",8 and LOAD"SPIKE",8. The problem only occurs when I use wedge commands.) |

probably best to check first if it does the same on real hardware :) |

Quoting jcomptonWith JiffyDOS: Ah, i have tested JiffyDOS compatbility in the early days of development, but forgot to re-check prior to release.
But i have different problems (in VICE): Spike loads and runs just fine, but Transwarp autoboot gets stuck.
Can be worked around by loading Transwarp (or Spike) with ,8 only (not ,8,1), then RUN.
Will contact you for testing the next version, then, but there is no release schedule yet. =) |

Quoting Groepazprobably best to check first if it does the same on real hardware :) Usually yes, but that kind of stuff (custom ROMs) is almost always a software issue that can be perfectly reproduced and debugged in emulators.
In this case, i had to buffer and restore COMSAV from this list http://unusedino.de/ec64/technical/aay/c64/mapjd.htm to fix the wedge issue and not use a certain drive ROM routine in the boot code. =) |
