Castlevania III - Dracula's Curse (USA)
| Address | Leangth | Type | Description | |
|---|---|---|---|---|
| $001a | 1 byte | RNG | Random line. This is incremented by 1 every step. It's used for randomization purposes and results in a linear pattern whereby a function X will return the same result X[n] steps later and X[n+1] will always be the same when n is a linear function. Of course, making n a non-linear function will yield results closer to what one would consider "random". | |
| $0018 | 1 byte | State | mode (07=debug) | |
| $001f | 2 byte | RNG | Random bump. While $001B is used most for random actions, this will vary things up a bit. This gets incremented and then $001B is added to it. This is done repeatedly between iterations. Basically, in GM terms, thisi is run between the last Draw event and the first Begin Step event. | |
| $0032 | 1 byte | State | Stage | |
| $0033 | 1 byte | State | Block | |
| $0034 | 1 byte | State | SubRom | |
| $0034 | 1 byte | Ctr | Lives | |
| $0036 | 3 byte | Ctr | Points will start with low byte. ($0036 0000xx. $0037 00xx00. $0038 xx0000) | |
| $0039 | 1 byte | Indicator | Player Always 00 (But could be someone else in theory) | |
| $003a | 1 byte | Indicator | Partner (ff=empty 00=Trevor 01=Sypha 02=Grant 03=Alucard) | |
| $003b | 1 byte | Flag | Character Index?? SubweaponObj?? | |
| $003c | 1 byte | Ctr | Health Player | |
| $003d | 1 byte | Ctr | Health Boss | |
| $003e | 1 byte | ?? | ?? | |
| $003f | 4 byte | Bank | CHR Bank ?? | |
| $0044 | 2 byte | Bank | CHR Bank ?? | |
| $004b | 4 byte | Bank | CHR Bank (switchable without crashing)?? | |
| $003f | 4 byte | Bank | CHR Bank ?? |
