Re: ADFFS on A3000

Post by sP1d3r » Tue Oct 01, 2019 2:16 pm

HI

I'm a new member and I'd like some info and advice about using ADFFS on an A3000, please.

The double density disk drive makes transferring ADFFS onto a hard drive a problem, but many JASPP disk images are less than the 720KB maximum file size for transfer using DOS-formatted floppies.

I've had problems with games that use more than one disk and imaging an A3000 disk is possible but the A3000's rendering of the process lacks things like text in option boxes, it only shows 1 blank character for an option in a box that is 1 column wide.
I tried to image my copy of Nevryon onto the hard drive but the second disk was copied into the first disk image in my ADFFS disk image directory.
I downloaded the Jaspp God's Game archive, extracted the uncompressed disk images onto a USB floppy disk drive and decompressed them once transferred and the game works, but the second disk doesn't appear to be loaded and games can't be saved.

I haven't tried to change any disk image filenames on the A3000 as I don't know whether the games would be recognised by ADFFS without being the ones that they already have.

It was nostalgic to play games that I remember playing on the the computer when it was new, but the way that ADFFS works is just as interesting!

A common problem, unless you can get the machine networked in some way, or transfer via serial or ZIP drive.

I recall someone having that issue before and I think it was due to out of date Modules in !System. Try updating them with the latest System resources file from ROOL, failing that try UniBoot.

Make sure you select disk 2 in the floppy drop down list, otherwise it won't image correctly. You may need to shorten the filenames to Nevryon1 / Nevryon2

I don't recall if Gods can be HD installed, when running from floppies use CTRL+SHIFT+F2 to switch to disk 2 when prompted.

JFD files contain metadata so the filename doesn't matter. In multi-disc sets, the filenames need to be identical with the last character being the floppy number. eg. GODS1 and GODS2

Glad you've found it useful.

Hi Jon

Thank you for your response, I'm very grateful for your expertise.
The filenames of the disk images in my ADFFS disk image directory were the truncated ones from Dos-floppy file transfer, e.g. GODS (1 1~2.J so I've changed those.

I'm trying to update !System on the HD with the PlingSystem.zip from ROOL and I've realised that I should've copied the modules from RO2 !System, the only modules were SCSIFiler, Basic64 and SerialUtil.
So far the !Sprite files have been copied into a Themes folder and I get the message 'Can't find '.Library.Basic64' Bad Directory.
I'm wondering which boot directory is referred to in the !SysMerge file in connection with the fall back copy of Basic64.
I know that I don't use a desktop boot file, but as I don't really know what I'm doing with RO3 I'd like to ask if it would be a good idea to make a !Boot file that opens the root of the HD to try to continue with the update?

Don't try to update !Boot yourself, use !SysMerge. It will update all the !System files correctly.

If you've broken !Boot to the point it won't boot to the desktop, just rename it and replace it with UniBoot, then use !SysMerge to update that with the latest Modules from the ROOL archive.

Hi Jon

Thanks for the advice, I'll continue with trying to update the !System file.
The first time that I surfed the APDL website, some time ago just before or just after David Holden passed away, I saw a utility for transferring 4th Dimension games to hard disk. It only worked with legitimate 4D disks but unfortunately, because I didn't have a hard drive then, I didn't download it.
Although I've tried looking on APDL many times I can't find the utility again, so unless I can transfer Nevryon floppy disks to my SCSI2SD HD using ADFFS, I'll have to rely upon the floppies.
Nevryon is a lot like R-Type but it's distinctly different and I still like playing it occasionally.
