I have tried, and managed to port Y** with DSTT into my R4 and got it working. My R4 no longer obsolete now !
I can't find the Y**1.bmp and Y**2.bmp any more in the web for obvious reason, so I replaced them with my original bckgrd1.bmp and bckgrd2.bmp, and it worked !
There are some imperfections in the whole setup, such as the DS hang after activating the LRXYAB reset, and Jap games were unable to load ( perhaps due to the changing of the setting in the Y**.ini from Jap to Eng.
Overall, my R4 can now be updated to the latest dstt fw ( fw latest update 17 Jul 08 ) and got those previously v1.18 unplayable games like Incredible Hulk working.
Those bro out there with an obsoleting R4 ( fw last updated in Apr08 ) may want to read this thread on gbatemp hxxp://gbatemp.net/index.php?showtopic=97615
(edit the links to make them work replace xx with tt to make the link live)
