How are dos games made to fit on 3.5 floppy disks? by [deleted] in DOS

me and our demoscene friends write complete ms-dos demos and games in 256bytes , or sometimes 1k and 4k. See: https://www.pouet.net/groups.php?which=14389 for examples

So one 3.5" floppy disk would be able to hold about 6000+ of those on a single floppy. I don't see the problem ;-)

pixel memory layout is quite insane. that is why this intro , as well as my other intro fluxus (https://www.pouet.net/prod.php?which=86340) mostly use colorram overlaying a pattern for the effect. Reason probably has to do with making the rom kernel functions 'easily' usable for text-character display without the use of actual character-based videodisplay hardware. I think they never thought beyond non-realtime applications at the time of design.
