FD2000/HD/1581 versions of multidisk games
Hi all,
I'm right now playing Ultima V on my C128. And even though I have a second drive connected I find the disk swapping extremely annoying. I wonder if one of those jewel crackers out there would like to do a version of that game (or other multidisk RPG like Bard's Tale II+III, Dragon Wars, just to name a few) that run from a single 1581/CMD FD2000/CMD HD or IDE64 (even 64HDD would be nice)?
I did a little research on Ultima V and discovered that the majority of the files on the 8 disks is redundant data! Actually only about 2 files per disk differ from files on other disks with the same filename! So I could imagine that all it takes is to modify the main program files, add a few branching instruction depending on the location of the game (Dungeons, Keeps, Towns...), rename the non-redundant files and adjust the main program files to load those renamed files instead.
Am I just blue-eyed, or do you think this is doable with reasonably low effort? |

Aye!
However, mine is an internal FD 4000 unit, inside a c128d computer. Does that count? :)

I'd like to know, if there are other ROM-versions around except V1.40. Could you guys please check the start-up-message? And perhaps even the ROM-checksum at $8002/3? |

Sorry for some degree of thread hijack but I'm also now experimenting with 1581/CMD FD/CMD HD fastloader support (with motive of integration into MW4 & release of information on covertbitops). Anyone interested in testing please mail to loorni@student.oulu.fi
(and thanks to DocBacardi & Ninja for support) |

Hmm, I hope you guys did not forget about my question about FD-ROMs during the time when CSDb was offline. I am still very interested if there are different versions around, especially concerning FD4000. Please help! |

I have uploaded a testrun of the new iffl loader here:
http://home.eunet.no/~ggallefo/gallery/iffls35.zip
I want everyone of you who own a FD or HD to download this file and test that this is working. I know that FD
disks have 3 different modes, but Ninja says it should
work in any mode. Well, I just need you to test this
for me. Then I can start using this routine.
Stats:
* The drive scanning should take 10 seconds. (++)
* Iffl to REU completed in 22 seconds on my 1581.
* Iffl to REU completed in 1 minute and 20 seconds on my 1541.

NTSC C128, FD2000 1.4 native partition, 512KB REU
I get about 20 seconds buffer-to-REU time with all configurations: Warp, Normal/JiffyDOS, and Normal. |

Whiteflame, cool! Thank you! :)
The difference between warp and normal can only be
seen when you DON'T use REU. |
