Renegade is a 1987 game programmed by the same programmer as Gryzor.
Technical
- Sprites are stored upside down in memory.
- Sprites are stored as mode 0 with pen 0 as transparent.
- Sprites are flipped by code in realtime (e.g. the facing right sprite is a flip of the facing left sprite).
- Some parts, such as the blue jeans are seperate, so some characters are composed from more than one sprite.
- Sprites are stored as follows:
1 byte normal (to write to mode 0 screen), followed by 1 byte with pixels swapped, then this repeats.
It is believed this is done so that drawing a sprite facing left, and drawing a sprite facing right will take the same cpu time and so that the frame rate will remain more constant.
- Supports 128K RAM. All parts are loaded at once.
