Type: misc/emu
ShapeShifter is a multitasking shareware Macintosh-II emulator for
the Commodore Amiga computer. It allows to run Macintosh software
concurrently to Amiga applications without hardware add-ons or
modifications.
Some of the emulation's features:
- Color display up to 256 colors on AGA Amigas (16 colors on ECS)
and up to 16,7 million colors on graphics cards (Picasso-II,
EGS and CyBERgraphics cards are supported)
- No MMU required, even runs on A1200
- Macintosh hard disks can be simulated in Amiga files or Amiga
hard disk partitions
[unregistered version has no hard disk partition support]
- Can use Amiga floppy drives, serial, parallel and SCSI ports
from the Mac
[use of SCSI not possible in unregistered version]
- Mac HD disks can be read directly with an HD floppy drive,
Mac 800K disks cannot be read, Mac 720K disks, however, can
- Multichannel sound output and parallel-port sound digitizers
supported
- Text clipboard sharing between Mac and Amiga
- File handler to access Macintosh volumes from the Workbench
- Speed comparable to a real Mac with equivalent hardware
Requirements:
OS2.1, 68020 processor, 4MB of RAM, HD floppy drive recommended.
A copy of a Macintosh 512K or 1MB ROM and the Macintosh system
software are not included, but required. The ROM can be read off
of a real Mac by using a supplied program, the system software
can be bought from Apple. Note, however, that reading the ROM is
only legal if you have bought the ROMs or own a real Macintosh.
Changes in V2.0:
- Pre-emptive multitasking
- Quickstart now works reliably
- Bug in stack handling corrected
- Graphics cards in 24 bit address space work with ROM 34
- CyBERgraphics 15 and 24 bit modes now work, selecting a
CyBERgraphics mode will automatically set the color depth
- Needs no special ROM sub versions any more
- Setting for task priority removed
- Macintosh reset routine revamped
- Italian catalog files
- When the selected amount of Mac memory is not available, you
can choose to use the largest free block
- Numerous internal corrections and improvements
- SCSI IDs individually switchable, an error when accessing
ID 0 will no longer cause the other IDs to be skipped
- The graphics refresh is now done by a subtask, enabling the
Amiga mouse pointer will prevent any refreshes
- ROM write-protection is now choosable
- The FileDisk driver will no longer open files with empty
names
