Raw Blame History

// Zelda UCode - CRC: 0x09CD143F
// This is a very complex little ucode. Quite a bit more so than AX.
// It also seems to use features of the DSP that AX neglects (the reverse is true as well,
// this ucode doesn't seem to use the hardware ADPCM feature at all, instead opting to
// decode a different ADPCM format manually).
// The value 0x50 is VERY common as a loop size. Many, especially intermediate/output
// sample buffers seem to be of this size. Half that size, 0x28, is also seen.
// MemMap
// 0x0400 to 0x04C0 - Some kind of CommandoBlock
// exception vector
