But writing optimized asm code (I mean 32-bit pentium code) is hard. Believe
me, I've done that for quite a while. You can't just write the asm mnemonics
sequentially, for example, you need to reorder them to follow the instruction
pairing rule.

There are *too many* rules to remember/follow: instruction pairing rules,
scheduling rules, caching rules, AGI avoidance, branching rules, avoiding pipeline
stalls, etc. Fortunately the pentium II has a feature (out-of-order execution)
that simplifies some of those rules.

On the other hand, C and C++ compilers have the ability to remember those rules
and trying their best to follow most (if not all) rules.

However, C/C++ compiler can't do harcore asm tricks that human can.

Anyway, good luck with the "A Very Good Idea" project. I already have my own
game project but I'll help if I have spare time.
