Which is better C or Assembly Language (ASM) for development ?
Assembly language is what the majority of commercial GB games use. One reason for this is that no serious C compiler has been available for the GB until GBDK was released. Another reason is that C is terribly inefficient. A C compiler can often generate 8 to 10 times more code compared to optimized assembly code. As GB ROM cart sizes get larger this makes less of a difference unless you are talking about ROM bank 0. ROM bank 0 is a major bottle neck for many commercial games. Some code must reside in ROM bank 0. Often the amount of code that must reside in ROM bank 0 is larger than a person expects until he gets deep into a large project. Commercial GB programmers often have a hard time fitting all the code required in ROM bank 0 when using highly optimised assembly code so using C provides even more of a challenge. Assembly code that uses the HALT command can save up to 5% battery power compared to a similar program written in GBDK even if the GBDK program uses HALT as well. The reaso
