Happy new year and that. I decided that with the new year should come a new burst of working on this ´ere emulator, so I decided to delve back into the code. I´ve stopped progress on the dynarec project, it being too massively large to handle at this time. Instead, I´ve pushed on with the other major missing part of the emulator; DS graphics.

The first task, of course, is to handle that strange VRAM banking business. I believe that, with a set of hacks implemented today, most of that is up and running; there are likely to be rather a few bugs in that implementation, of course, as with most parts of this emulator, but the substance of the mapping is there. There are a few things missing, like the WRAMCNT register, but they should be along in short order.

With the current codebase, you still won´t see any output on the screen, since there is no renderer of any kind in the GPU code at the moment. However, I´ve confirmed that at least the one demo I have to test does indeed write to VRAM, and in the right place, so something must be working correctly. I guess the next step is to actually render something, to get some output from the DS side of the emulator.

Oh, yeah. First release of ´06! Let´s hope that heralds a period of productivity on this thing.
