ETA for update to 44.10? dfhack r2 has been released.
I was able to use this tileset with 0.44.10 a few weeks ago by building DFHack and TWBT for it, and then copying the raws, graphics, settings, and so on from the 0.44.09 download. This is certainly something you could do yourself.
I'm interested. DFHack for 0.44.11 juust released. How do I do this?
Get a fresh copy of 0.44.11. Clone the DFHack source code (
https://github.com/DFHack/dfhack/), and build and install it according to its instructions, making sure you tell it where your DF is located. Clone a copy of the TWBT source code (
https://github.com/mifki/df-twbt), then build and install it according to its instructions. It will need to know where your DF and your DFHack are. Then copy the DF config files and graphics from a previous release of Meph's tileset into your DF installation. Make sure you get the overrides.txt, since that's what tells TWBT which tiles to use for which things, and the dfhack.init script, which turns on TWBT.
At this point you have to decide if you want all of the modifications to the raws or not. I don't think any of them are vital, but many of them are worth having. Merging is important here; simply copying the raws from Meph's tileset will cause you to lose access to some of the features and bugfixes in 0.44.10 and 0.44.11. On the other hand, merging is complex and detail-oriented work; it'll take care and attention to detail to do correctly.
