my plan is: convert the ppu to be a device, see if I can fix any issue in games which don't start, and then take a break from this driver (waiting for cool things to happen on the CPU and timing side).

once RTO issues will be relevant in the currently huge buglist, I will put the video rewrite on top of my todo list.
with current svn, we now almost compare line-per-line code and output of MESS vs. bsnes and I already see this as a quantum leap compared to the 0.136 source code (not to mention the number of bugs that have been solved and the missing effects that have been added in the meanwhile)
