I had a G1 before with 1.6 and ran PacMan with no problems. Sadly my G1 was stolen in Cambodia. I live in Vietnam so I bought another one in the USA and had to wait a month for a friend to bring it over. It came with 1.1 so I had to upgrage to 1.5 then upgrade again to 1.6 (is this the correct way to do it?) But now when I installed the PacMan game it works fine but the whole game flashes. Did not do this before. How do I fix it? I already reinstalled it and even downloaded another PacMan file. Stll flashes...
