1.  FILE MANAGER V2.76A

A more powerful SD memory file manager

• File filtering: only loadable files are shown depending on FDD / HDD mode.
• Greatly increased file display capacity: 1,500+ files, which is practically enough.
• / SWAP function: swap D1 <> D2 files.
• Key input is not case-sensitive.
• Screen automatically refreshes after deleting a file.
• Fixed the MORE display [+] bug.
• Image file size is displayed in KB / MB.
• Removed <VOL> display.

 

2.  Smart Cache Bug Fixes and Improvements

Fixed a possible write problem caused by an error in the write-back cache function when using HDD mode.

Smart Cache and several other parts have been accelerated using ASM.

SmartPort support is ready.
It will work immediately after upgrading the ROM chip BIOS.

Expanded HDD capacity:

When supported by the OS, up to 512MB HDD read/write per drive is possible.
ProDOS itself has a 32MB limit.

This version also includes fast FDD reading.
However, depending on the NIB image, some images may still read very slowly.

If you copy the disk again using a disk tool on the Apple II, it will be automatically optimized.

You can overwrite the disk image with itself using copy tools such as Disk Muncher V1.0 or Copy II Plus.

• Supports many FDD disk copy programs

Tested/supports many programs without write errors, including:

Disk Muncher 1.0, Crazy Copy V1.0, Copy II Plus, and many others.
