Dreamload question
Hi!
Does anyone know how to 'convert' ide64 fixed games to dreamload?
I saw that there exists an ide64 version of 'Rick Dangerous 2'. How do I add the new loader?
It should run with the MMC64... |

much easier to create a kernel patch for a new device than adding support for a new device to <insert insanely large number> games.
demos, yes, those are a completely different story. |

How much RAM the kernal patch would approximately need? I guess it would need to be relocatible to be useful.. |

Well, at least you won't need a buffer there. But some mem to store MMC-configs? Dunno, maybe Baccy stores everything in RR-Ram or something :D But as I said, KERNAL-thingie is just an idea at the moment and Baccy is busy as hell... |

dreamload on mmc also works without the RR, i think it only uses RR as a possible buffer. |

I meant "will store". This was for a possible KERNAL-thigie. Dreamload can use RR, but does not need it, as WVL said. |

How many new & old demos will be fixed with dreamload?
I doubt people will use it as their standard loader.
However, it would be quite cool if every new demo would run from mmc64. 8-)
edit: kernal support would solve alot problems, but if a RR is required... :-l |

I'd appreciate the jewel crackers taking Dreamload into account much more than demos. Retrofixing games like Ultima or all those multidisk RPG games to work from MMC64 would be a blast! :-) |

Well you still can't save on MMC64 (and for saving in general, you need to detach the loader and be prepared to run the $1000 byte init routine again)
Furthermore, I guess pride of using in-house loader can never be underestimated :) |

Indeed. Also nothing speaks against making other loaders more compatible. And Dreamload still has the big disadvantage of only allowing one device on the bus. (So does my loader, but that will change)
As for me, the initial idea was to make the _fastest_ irq loader for demos, and that's still the primary goal. That means best performance on Commodore 64 + 1541, other configurations are of less interest. Many demo producers have the same primary goals, and that's why some of them prefer my loader.
Recently, i added a kernal fallback that works with exotic hardware as long as they work with the plain iec protocol or if there is a kernal patch supporting them.
I will add more compatibility (1581/FD/HD without kernal fallback) later, but primary aim still is to max out the speed on a 1541. |
