Scripting: Yes, since you'll create user-generated IPF files, and the IPF codec is capable of randomizing the data to the level needed for this to work.
Whdload: What are you exactly trying to do? Whdload uses IPF lib directly, but that's genuine Amiga code. You will have to use:
- genuine v5.0 Amiga library on real hardware
- use normal disk imaging with emulation instead of direct IPF access of WHDload, then the kind of image used will be completely transparent
If it's some other issue please post an exact repro and details
So did you try them as CTR with WinUAE?
I've checked and your dump was not on the FTP - you uploaded about a dozen stream dumps in total...
