Argh... not sure if I'm doing something wrong so thought I'd finally ask. I Googled the error message but the only match was somebody asking me the same question on my own forums.
I haven't built mess 0.140 yet so am using 0.139, but get basically the same result on earlier versions as well (though the options and rom files are obviously different when I go back as far as 0.124). As usual I'm running YDL 6.2 on PS3 (ppc32).
I try starting it like this:
mess apple2gs -flop3 /path/to/game.2mg
And it starts to load normally, I enter OK to continue, get a screen full of colors for second, then it shuts down with:
Ignoring MAME exception: ADB command 0xe1 unimplemented
ADB command 0xe1 unimplemented
Bad image? Bad user? Any ideas?
