Rollei R3 - how to develop?

I got this film "by accident" and didn't know it is a multi-layered and require special developers.
Shot as 400.
Rollei developers are no available in our area.
So I restricted to more traditional choices: d76/id-11, microphen, XTOL or Rodinal.
I read over internet that d76 isn't worth to try, becouse it doesn't affect all layers of this film.
What about XTOL and Microphen?
dev.time in XTOL is huge - 24/29 min, does it require agitation?
I'll almost die to agitate for 29 min

I've done R3 with Xtol 1+1, with 24 minutes, agitation 10 secs per minute. Yes, you'd better get a few rolls together in a big tank, unless you have a roller base or Jobo... The film looks okay, but in the end I gave my leftovers, ten 120 rolls, to a darkroom pal. It doesn't matter that I paid peanuts for those rolls, it ain't worth the trouble (unless you got the special soup).

It was soo hard to find this: Dead Link Removed
