CPU: Added emultaion of the IntrWait and VBlankIntrWait SWIs

CPU: SWI 0xFF (0xFF0000 in ARM mode) outputs the string pointed to by R0 to the debug console

MMU: Small optimizations on some of the load/store functions

GUI: Added a disassembler, memory viewer and debug console

GUI: Improved the palette viewer

GUI: If a filename is given on the commandline, the emulator will try to load and run the file

That was fast hehe.. thanks to Two9A for the direct news.

So it turns out I had a pretty poor implementation of touchscreen, in that it only picked up the coordinate values when I clicked the button. I've changed it to work by catching mouse-move messages as well as mouse-button messages, and now the outputs of both David Rorex's first demo and his Minesweeper are much better. The issue still remains that the touchscreen isn't calibrated, though; that means the position of the touch is offset from the position of the cursor. I'm not sure how to fix that.

 

In other news, the DS palette viewer is now complete. You can see background and OBJ palettes, from both GPU cores. I'm hoping to pick up a configuration editor dialog from somewhere soon, so you can all finally change your key mappings with ease.

I apologize were a little late on this. I don't know what happened.. but somehow we missed 3 releases.

I said I'd keep looking at the core, and I did. I ended up finding the major error relating to the jump-to-0 bug. I suspected that it was to do with the stack getting corrupted somehow, and with some good debugging help from various sources, I tracked it down to the stack pointer getting changed. It turns out that Thumb ADDSP-imm has a reciprocal mode, SUBSP-imm, encoded by the same first byte. Fix that, and suddenly nothing jumps to 0 anymore. Mind you, it's still the case that nothing works.

 

Elsewhere, I've noticed that when the emulator is put into animated scanline mode, the output screen starts flashing like a madman. It's because the MMX word-flip operation to turn the colours the right way up gets applied every scanline, to the same buffer as its previous output. After adding yet another output buffer, the screen no longer flashes in a psychedelic manner.
