Hi, I recently received my new Harmony & immediately flashed it to the v1.05 PAL50 bios. So far everything is good except for random crashes when playing any PAL dump of Phoenix. Game loads fine but will crash the whole 2600 during play or attract mode within a few minutes. Weird thing is, there seems to be no consistency asto how long it will run before bombing out. I haven't tried the NTSC version of the game but as my 2600 is a PAL, Sunnyvale made, light sixer modified for composite video, it should be possible I guess. I have another modified sixer ordered and on its way so will attempt with that when it arrives. Just wondered if any other folks have had this issue with this game. All other games seem fine so far. Thanks
