Hi all, I have been online reading up about Atari 2600 cheating in emulation. More often than not, a Google search on the topic tends to bring up Bob Colbert's Cheetah. Primarily I'm looking to cheat in Adventure (mainly I would like to be able to walk through walls). Can anyone tell me whether it is possible to cheat in 2600.emu? If it's not possible to cheat in 2600.emu - should I be looking for a "hacked" Adventure ROM that has a "walk through walls" cheat already written into it? Any help/guidance/suggestions will be appreciated. Thanks! Matt P
