Things haven't really progressed much after this video. I have been very busy with school (have had with even more work than at the moment), part-time job, and other things. Even now, a certain seminar course is taking quite a lot of my spare time. That (along with the rest of studies in this Spring) will be over in a month or so though, so after that I'm certainly going to make faster progress. Until then, I'll try to get something more done like the following two routes.
I think it would be somewhat unfair if I sent you a patch file directly and not to share it others as well. I was however thinking (like a year ago) of putting up an additional release before the whole content planned for beta 5, but at the moment, have less plans of doing so. It hopefully won't take that long to get actual beta 5 done, so once I'm done with that, you can transfer the hack into an actual hardware :)
Thank you E-cat420! :)
