LisaEm 1.2.0 released - No ROMs? No Problem!!!
Posted by: sunder on 2007-09-24 20:13:45
LisaEm 1.2.0 is available for download right now, from the usual place: http://lisaem.sunder.net/downloads.html

Many LisaEm users have complained that ROMs are too difficult to extract. The new version of LisaEm solves this by allowing you to run with out a ROM. If you wanted to try LisaEm, but couldn't because you didn't have ROMs for it, now you can!

LisaEm emulates the functions of the Lisa Boot ROM as well as the Dual Parallel Card without requiring a ROM, and allows you to boot into Lisa Office System. If you've felt limited by only having a single emulated Profile hard drive because you didn't have the Dual Parallel ROM, the new version also emulates these, without requiring a ROM.

All you need is Lisa Office System and LisaEm.

As this is the first release of this feature, don't be surprised if you encounter bugs. Please report any unexpected behavior so that I can fix it. 🙂

Additionally, I've added two movies that show how to install Lisa Office System and MacWorks. (MacWorks still doesn't work properly on LisaEm however.)

If you'd like to support this project, you can do so by sending me something from my Amazon wish list. (Used books and DVD's are perfectly fine with me.) The trains are for my kid. 🙂 http://www.amazon.com/gp/registry/wishlist/14EOBF86ARMDT/ref=wl_web/

I'm just curious, how can you run it without ROMs? Are you including the ROM code within the emulator itself?
Posted by: sunder on 2007-09-25 03:16:31
There's no actual ROM code included in LisaEm.

Instead, when the operating system calls one of the function normally handled by the Lisa Boot ROM, that call is handled by the emulator in native code, eliminating the need for a ROM.

If you do provide a valid Lisa Boot ROM and/or the Dual Parallel ROM, LisaEm runs as usual, executing code from that ROM.
