Historical Mystery Adventure (J) RGB fix?

[SlipperChin]

Just got Historical Mystery Adventure, but this game will not work on my PAL DC, as I get no picture due to RGB protection. The game works fine with a RF cable but i would like to play it with my scart lead, I've tried PALPatcher 1.1 without success (did not find anything) anyone got any ideas on getting this to work?

Cheers.............

I remember a trick one could try for this. Start the game with the RF-Connector plugged into the DC, then wait a while until you're ingame, then plug in your RGB-Lead. I heard you can bypass the RGB-Check this way, but it failed on Looney Toons. Probably it works for you.
BTW, I don't know of any fix for it...
