得益于修改思路的进一步优化,原本是通过文件的Trainer在7000-71FF固化程序,让程序的精灵端口跳转到7000执行关卡选择的程序(包括显示STAGE),Trainer在ROM载入时就把Trainer的512字节载入到7000-71FF了,本来想通过按键跳转的切BANK程序里面把原本Trainer的数据复制到7000-71FF,这样ROM就不需要Trainer就可以让7000-71FF充满我写的选关程序了,然而,ROM运行时首先运行的是精灵写入程序,那时候按键程序都还没有开始执行,此时7000-71FF一片空白,跳转到7000只能死机喽.$ w! i' A# r8 B, K( @5 c& X& @
然而,今天想到一个思路.1 b3 h. c4 l4 C! D* @
1.找一个大约20字节的空间A,把精灵写入指令改为跳转到A写上: 7000-71FF是否已经写有数据(71FF为FE即可),有的话跳转到7000执行,否则执行原来的精灵写入程序后回去.- n3 y& o) a; X- s5 P5 L
2.按键部分加上数据复制功能: 判断71FF是否为FE(是的话数据写完了,跳过写入程序,不是就复制数据块)没有复制完数据的话就把Trainer数据块复制到7000-71FE,复制完将71FF写入FE5 T7 \# h5 Q) F% n
3.这样一来就可以完美地使用空间6000-7FFF来写更多程序了(数据可以写入到6000-7FFF)., }. X) P$ N& s5 j8 [. U: D& Y: N% \
