X-Git-Url: http://4ch.mooo.com/gitweb/?a=commitdiff_plain;h=cd8d88b23a2c9a5f0a3df949f57ff81a44b6aa94;p=16.git

showing row and colum drawing i optimized it to only draw at the end of walk. this explains why it is much slower than it was before panp is now sp and p is back to it self 0.exe now replicates the functions of 16_spri
