Hi John,
Not too difficult to be honest.
You may need to re-locate the TRS-80 exe code, as most disk loadable games begin above $5200.
Screen accesses will need to be patched TRS-80 ($3C00-$3FFF) => HiMEM on Bee.
You'll need to write routines to pre-load the programmable GFx chars on the Bee with TRS-80 Gfx.
You'll need some routines which take Bee Keypresses, and simulate press/release in the TRS-80 keyboard area ($3800-$3880) (iirc).
Take a look at the BIG-5 conversions downloadable from here. (Galaxy Invasion, Cosmic Fighter etc.)
Most of that work will already be done for you.
I did a few Exidy Sorcerer conversions a few years ago, which is a very similar process.
Cheers,
Leslie
