Deunan has updated his Makaron blog again. He has released Makaron Test 9/4.

Makaron Test 9/4 for those who like to experiment.
I'd urge you to wait for T10 as this is a bastard mix of current (broken) dev 
and older T9/2. I got it to compile and run but that's about it - not tested.  
It does include the DMA changes that should make WinCE games more stable but I 
make no guarantees.
It's still using old GD code which means (with the DMA changes I've made) it  
will most likely break Street Fighter Alpha and some other games.

Use the supplied plugins and Maple.ini to get vibration support and use F12 
menu to enable VMU LCD overlay. Also, make sure to change sorting mode because 
it defaults to "Alternate" which turned out not to work for some games.

This release goes beyond experimental, it's downright partisan :) I'm not 
kiding you - unless you like 'em rough stay clear. I'd like to have some 
feedback on vibration support for upcoming T10 and that's the only reason it 
exists.

PS. No changes to full-screen mode in this one, and no support for 16:X aspect 
ratios. And Yuki, stick to your T9/3 for now :)
