Thanks for your help already. The current version would no t run without it!

There are a few functions in Einstein (look for "Albert") where I tried replacing ROM calls with native calls.

There are a few disassemblers available that are required to understand what's going on in the ROM. One is actually built into Einstein. If you compile the command line version (using the outdated Xcode 2 files) you can even set breakpoints in the ARM code and dump sections of memory (it would be nice to get that feature back into the current Einstein: just imagine the ability to open a debug console - nice!).
