TI 1 vs TI 2 Factory ROM patches
 

I have a Virust TI 1 keyboard. I can see that I have both sets of Factory ROM banks in my browser. They seem so different from each other.

If I used the TI 1 factory patches (A-S), am I missing out on a bunch of new patches that utilize the new OS features?

The TI2 Factory ROM has banks A-U.

And advice? Are the TI2 banks simply reorganized TI1 banks? Or are there new patches? When them being in a different order, its hard to tell.

There's new patches in the TI2 ROMS. You can have a list of them on the official forum, a user actually took the time to make a pdf with the correct names for the TI2 ROMS (whilst the Access document is accurate for the TI1 patches)
