This version is more responsive to key presses and a simple effect to switch slides has been added. Call the program with the %e option, to enable the effect.
The effect is implemented twice, once in C and in assembler. The pre-compiled binary is compiled with the assembler version.
Use "make ASSEMBLER_EFFECT=1" to compile the asm version, by default the C version is built. This project is an example of mixing C and ASM code in a M20 cross-compile project.
