Thanks for all your replies guys, I wasn't aware there was another thread focusing on this topic, I did a search on AC/DC before I started this one, and didn't find anything on code after looking at the top several hits...
Anyway, it seems that the code is very good, whether it's truly complete or not.
What I'm picking up is that the lower playfield is probably the weakest link in the code... for it to not be connected in any way to the game is something that could certainly be improved upon IMO... so there's no features activated in the rest of the game like 'super something' or an EB to be earned down there? It seems a common thing for the additional stuff on the LE's over the pro's to have poor integration with the rest of the game... Understandable I guess bearing in mind the main effort on code will be on the part that's applicable to both game versions... I have Transformers, which I think is a great game... (not complex, and therefore clear to the player) the Starscream and Ironhide 'playfields' don't integrate much with the game, but at least you can earn an EB at Starscream, an get super spinner and super pops at Ironhide...
Looking forward to finally getting Luci in the house!!!
