// Zelda UCode - CRC: 0x09CD143F // This is a disassembly done using an outdated disasm. Need to redisasm and transfer // the comments. // 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.
