   Several years ago I was dinking with a Laser 128, and later with the   
   SimSystem IIe emulator which had a similar - it seems, string-hacked -   
   firmware.  I got to thinking about the occasional programs I'd try with   
   the 128 or SimSystem IIe that would blow up.   
      
   Sometimes, these were old file-cracked single-load games, which I was able   
   to get to work by using the old System Master to load an Apple ][ ROM, and   
   then run them.  That didn't always work.   
      
   From what I understand, the hardware isn't quite enough like the Apple //e   
   or //c, that a //e or //c ROM could be used unmodified to drive a Laser,   
   or a Laser ROM to drive a //e or //c - but I suspect there isn't much   
   difference.  I came up with the idea that perhaps, since most if not all   
   of the source to the parts of at least some versions of the //e and //c   
   firmwares DO have the source published (excluding FPBASIC, which isn't   
   really relevant to this apart of having to be brought in from a //e or //c   
   ROM), a new ROM could be developed which is, for all intents and purposes   
   as far as any program can tell, an Apple //e or //c ROM and should be able   
   to run on a Laser 128 even those programs which usually crash.   
      
   That said - it's a matter of implementation, of course: it would need to   
   be tweaked to get around those hardware (ROM-banking) differences.  And   
   I'm not really sure what-all those differences actually are.   
      
   I'd try to do even more if I were sure it wouldn't break other stuff (such   
   as the ProDOS-8 clone check)...   
      
   -uso.
