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? |

I don't use the BAM copy like you. Perhaps this part is bugged? I'm a simple 1581copy sthing.d81 a: |

Some news regarding FD2000/4000 :
The bug we had with those drives has been
fixed, and our next games featuring the iffls routine will
work for FD users as well. It has only taken 2 years to
find out what was wrong....
Look out for iffls v3.5.
Many thanks to Ninja/Dreams for debugging.

That's great news! Will the games with the old routine be re-released with the new one installed? That would totally rock! |

I am considering. I do have backups of most of my work files from the last 2-3 years. The fix is rather easy to do, the old iffl routine will work for FD if you remove 4 or 5 BCS lines in the scanner and loader code.
If you want to test for yourself I can tell you what
to do....

Actually this makes me wonder, how many browsing these
forums are using FD-2000 or FD-4000? Say 'AYE' |

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? |
