Make "quake.elf" work.

Implemented instructions DIV1, MTLO and MADD.
Fixed another stupid bug while working on DIV1. There wasn't any allocated variables for the HI1 and LO1 registers, and was using unexisting array indexes 2 and 3 of variables HI and LO instead. Everything seems to work nice now.  
I still have to let the whole thing run to see if there's missing instructions. And it's also running kinda slow and the 20fps figure isn't realistic for the same reasons explained in previous posts. After this, I'll need to make a decision whether I'll be working on supporting the other version that supports USB input devices or not. |
