This is a scan of the manual for Space Invaders for the Nintendo 64. I did not scan this item, this was scanned and posted by an unknown contributor at NintendoAge before the site was sold and subsequently shut down.
The CBZ can be opened in any program that can handle ZIP archives and you can get the original scans that way. Or you can use any CBZ capable program to read the manual.
(Please don't download the PDF, for some reason the site is recompressing the images and making them even less clear. Please get the CBZ instead.)
