It is more likely that the G64 is not completely clean. Slight deviations, such as different firmware (1541, 1541C, 1541-II) or disk wobble, should not be enough to cause a problem. Quote:

oscillation (weak bits) should be working. Honestly, with formats like IPF or P64, nothing special needs to be emulated to handle all copy protections. Unfortunately, no group has set itself the task of mapping C64 originals as P64 (IPF). |

Actually, a G64 track can contain multiple densities. It's just that no emulators (that I know of) support that, and it must be manually constructed anyway.

The effort to emulate this information with a G64 is quite large. The P64 is much better suited for this. |

"chessmaster_2100_s1[software_toolworks_1988](multi_density)(!).g64"
checked with nibscan: 0 tracks with non-standard density a quick look with an hex editor shows only standard speedzone entries. The necessary information is missing here to emulate this G64 |

Correct - to my knowledge nobody has constructed a multi-speed zone G64, and no emulator supports it. It would be very hard to detect that it exists via any automated tool, so it would have to be manually created.

Your experiences with NIBTools? --> https://www.lemon64.com/forum/viewtopic.php?t=66621

The ones from the testing collection, created by nibtools, don't seem to work , so not sure if they can be declared technically defective! (or they just need some other additional processing in nibtools) |

Can I assume then that the same applies to most v-max and rapidlok images too!? (from the collection) EDIT: I'll have to check that out first! (and then conclude) ---------- Editing G64 --> https://www.lemon64.com/forum/viewtopic.php?t=76624 Quote:
---------- @r.cade Thanks for the information I found on your site! (found under your signature) Edit: The past few days I have enjoyed reading and studying everything I found there. Now a lot of things are clearer to me, especially regarding how 1541 sees and reads tracks & sectors! (and also sync, header, data, gaps etc.) Last edited by amilo3438; Yesterday at 18:49. |
