Is worth to note that 0x3C is default multiplier even for PAL titles, so is not stricly related to framerate, | |||
but to vsync counters (where 0x3C is still wrong anyway..). Result of multiply is also compared at some point to vsync delay value. | |||

PS2 GX Emu commands are Big Endian unless noted. Every command size is 0x18, and unused data need to be filled with zeros. Commands which point to emulator memory have additional data, but command itself is still 0x18 in size. Data fields are just example values and can be changed to different value when needed. | PS2 GX Emu commands are Big Endian unless noted.
