Data Structure Documentation

◆ cmd_data

struct cmd_data

Even though I'm reluctant to do this, I've made this structure binary compatible with the SCE libs and ps2lib. In all implementations, a pointer to this data is stored in SIF register 0x80000001. Each routine that relies on this data can then use the data referenced from that register, so that even if a SIF library is initialized after this one, we should still work exactly as expected.
