Yeah, the arcade is definitely much harder than the TG port. I haven't cleared the arcade '88 yet, but I've cleared the TG port many times. Though, the TG port has essentially taken over as my Galaga '88/'90 default choice to play. Probably because it is easier makes me want to play it over the arcade. That doesn't mean the TG port isn't difficult - I'm stressed out playing that game from the moment I "Press Run" to the moment I finally destroy the last boss. It just wasn't designed to eat you quarters. heh I throw on the arcade version once in a while, but playing the TG/PCE port is honestly a much more enjoyable experience. Plus, graphically and in terms of music and soundfx, the TG/PCE port is extremely close to the original. It would have been cool if the developers included an "arcade mode" with a narrower screen, but I say that about every shootie that doesn't have that option.
