Instructions and notes
Parameters : r5 = Tile elevation
r4 = previous routine stack pointer
- 0x00 = X mod (X coord * 28 + preset value)
- 0x02 = Elevation
- 0x04 = Y mod (Y coord * 28 + preset value)
Returns : r2 holding Height data as negative value depending of slope type
- (Height*12) if halves = 0 or unsupported slope type
- (Height*12) + (preset/28)*12*halves (depending of slope see notes)
- (Height*12) + (1- preset/28)*12*halves (depending of slope see notes)
NB : is preset is 14 , same result for all slope

Notes
For notes below, (preset X)/28 will be refered as X and (preset Y/28) as Y. (1-preset/28) will be refered as anti-preset
So X, Y, Anti-X, Anti-Y (...)
Here is the details per slope type
0x11 : X or Anti-Y (smallest value)
0x14 : Anti-X or Anti-Y (smallest value)
0x25 : Anti-Y (always)
0x41 : X or Y (smallest value)
0x44 : Anti-X or Y (smallest value)
0x52 : X (always)
0x58 : Anti-X (always)
0x66 : X or Anti-Y (greatest value)
0x69 : Anti-X or Anti-Y (greatest value)
0x85 : Y (always)
0x96 : X or Y (greatest value)
0x99 : Anti-X or Y (greatest value)
