You're right - it's because of the analogue inputs. Take a look at the size of any centipede recording, and you'll see that they are a lot bigger than non-analogue games. Analogue inputs are 8 bit inputs, and moving the mouse a little can affect a lot of bits, so from frame to frame there's a lot of changes to store. With a joystick, you're probably not going to change its position more than a few times a second, and each movement only affects one or two bits, so the zip program can compress the recording really well. When you move a mouse, though, the 8-bit number(s) change with every frame, leaving less score for compression.(posted 9640 days ago)As far as disk space goes, the recordings take up most of the space at MARP (not surprisingly):
11.9 megs of graphics, including screen shots 47.5 megs of old versions of MAME 107.6 megs of recordings
