OK, I couldn't resist. I disassembled your cart image from Randy's site using Distella, and now I know why you don't make it to fit more text into your program: Apparently, you're storing the whole text as animations! This way, every bit that has to go through the scrolling process requires a whole byte of the (very limited) storage space. Of course, you could as well store whole animations this way, but for scrolling images, I find this to be very inefficient. As if the CPU wouldn't know how to shift images! Sorry if this sounds like I'd offend you, I'm only a bit... disappointed of your programming skills. OK, this way, you use up only 5 bytes off the VCS's internal RAM, but come on! It still has got 128 of 'em! This way, of course, for your cart your calculations make sense, and the scrolling engine may in fact be very small, but this causes a very inefficient way of data storage, which in the end leaves much less text space than a more sophisticated engine with an efficient data storage. Well, there also have been improvements from Pac-Man to Ms. Pac-Man...
