1. Slightly reduce data volume. In GTE, division is performed by reciprocal integration, and its inverse value is inferior in accuracy. It was obvious that the common value for each group was refined.  However, the calculation formula for refinement was unknown (There is only the Newton's law or the Gold Schmidt method as the theoretical formula When dealing with integers, how to round numbers is arbitrary by the designer, It can not be theoretically derived). Although it was unknown, it is not a large amount of data for software on PC I wish I could prepare the whole number as an immediate value table (This is effective also in terms of reducing the amount of computation at the time of execution) 
   When checking the calculation formula of the refinement indicated by nocash this time, since we saw an agreement in total, I decided to adopt the calculation formula.
   As an actual utility, compressed data which was 4000 bytes in old algorithm, It is reduced to 257 bytes with the new algorithm. Although the normal distribution data used by the SPU was held for all the sections, Because it is bilaterally symmetrical, we deleted the half section.
2. Center display of screen at startup

• The default value of Stall Rate (GPU - in) from 0x14 to 0x8 at the above review. I tried to change it, so it was quite probable that this was an enemy case It returned to 0x14

• Transfer rate (GPU-chain) is unknown from when it is about. It was fixed because it was invalidated. Since the tag part and the data part are too different in the rate, We made them separately, and we used coefficients of GPU-in for the data part.
