What about a framebuffer ? The pseudo-SVP would translate everything to a tile-rendered scene.
Just like the original SVP come to that.

The 32X Hardware Manual (valpocl.com/SuperVDP/32x_hardware_manual.pdf) states : Built-in SCI (Serial Communication I/F) : SH2 has one SCI channel. In the 32X, the master and slave are connected to each other making serial communication possible. If data receive interrupt is used, timing is effective...

Back to subject, I remember talking with devster (http://devster.monkeeh.com/) who quite discouraged me to do so. I can't find back the post, but he noticed to me that even inserting a single charcater in a 500 words document would take quite a long time. But, we're explorers, aren't we ? So, as far...

Unfortunately, I guess Chilly is right : I've never tested all this stuff on real hardware, and I'm afraid it won't run on actual 32x.
