Ok, thanks, now I got it clear.
But anyway this game has no 50/60 selector like any other JAP game, so I suppose it's just some auto switch...
BTW, I've read your post about unpatchable titles: I confirm that I've never been able to patch those titles as well.
And I would add Tsuushin Taisen Logic Battle Daisessen to that list, as it cannot be patched with any tool, although it is not a WinCE game...
Also, Memories Off and Roomania #203 looks more like a NUKE rather than a protection, since they don't work an JAP DC too.
Cheers!
