Every developer knows the feeling when finally he/she finds a bug and slaps to the forehead while mumbling: "How on earth was this thing ever been working?..."
Well, it just happened to me, I have fixed a bug that stopped the ROM from booting. It was a rather stupid mistake (as usually); for the details check out
the update.
In this other
minor update I have fixed one more nuance with the wrong addresses in the dumped PowerPC code log.
Right now the emulation advances even further in the booting process than before, when it stops with this cryptic message:
Compiling error: instruction or addressing mode is not implemented, but marked as implemented: 0x323b
Unfortunately, this is true: this is a move instruction with complex addressing mode (68020), which one is not implemented yet.
Since the move instruction itself is marked as supported and all the addressing mode is listed in the descriptor it busts me big time and calls me a liar. Fair enough.
I promise that I implement all the missing addressing modes soon. Honest.
I was so excited that I tried to run the ROM without compiling the instructions but in this case I got back to the previous problem: the reboot loop. :(
At least one bug was squashed again.
In the meanwhile
Tobias managed to port the JIT to
PowerPC MacOSX. For the speed check out
his comment. I hope he sends me the changes soon and I can add it into the main source repository.
