Technical Info The New Scroll Routine MSX more or less implies that you end up with a 8x8 block scroll routine if you don't want to use hardware sprites. Having said that, this new scroll routine pushes all limits, speed wise as well as resource-wise.   Akin Core Dump Display Fixed scroll window Up to four variable sized scroll windows (a.k.a. "cameras") Size: 240 by 128 pixels Maximum total size: 256 by 192 pixels Size fixed in code Number and size of cameras can and will be changed real-time. Example: Lay down a mine... extra camera window appears, showing the mine until it explodes.
