A simple sample program for Virtual Boy programmers. The source code came with every VUE-Debugger and was meant to introduce developers to basic hardware functionality. The demo consists of 5 programs, which can be looped through with the L and R triggers.
- Background Display
- Object and Background Display
- Background Affine Transformation
(Spinning Nintendo Logo)
- Background H Bias
(Vibrating Nintendo Logo)
- Inter Pupillary Distance (IPD) and Focus Adjustment
(Nintendo Standard Screen)
Interestingly, the code contains a bug, which caused some registers to not being stored correctly and possibly get overwritten. The sample program still runs correctly even if the register was overwritten, but when a developer based his program on that code, it caused annoying bugs, as happened in the development of Bound High (see our Interview with Hideyuki Nakanishi).
