This page contains notes for the game Akumajou Dracula X: Chi no Rondo.


Unknown/Incomplete Stage Data

Lots of unused/weird/unknown data between where some stages are stored on disc:

  • Between Stage 0 and Stage 1
  • Between Stage 5'and Stage 6
  • Between Stage 6 and Stage 7
  • Between Stage 7 Boss and Stage 8


LBA=0x001333 - Serpent battle, garbage graphics, bad ADPCM, weird PSG sound effects(like earlier complete stages). Replace third LBA in asset table entry corresponding to Stage 1 Alt Boss(Serpent).

LBA=0x001543 - Possibly earlier/alternate(?) stage 2'
