Re: [hatari-devel] Solved: Pure debugger, illegal opcodes, exceptions

[Eero Tamminen <oak@xxxxxxxxxxxxxx>]

Hi,

I pushed a fix to repository.

Pure Debugger starts now fine with WinUAE.

I also noticed that X-moon game works fine with it now,
but I'm not sure was it because of this change.

(For some reason the game stops while one keeps
joypad fire button down which makes it pretty
annoying to play, but otherwise it works fine.)
