Code:
0x200180: LD XHL,(0x4006) : E1 06 40 23 |
0x200184: LD XIX,0x0020018F : 44 8F 01 20 00 |
0x200189: LD (0x4006),XIX : F1 06 40 64 |
0x20018D: JP T,XHL : B3 D8 | here we can assume XHL eq 0x294CFEThat bit seems to use (0x4006) as something of a jump/return address. Even the setup code uses (0x4006) to pull out the address that will be jumped to, then it puts the return address into (0x4006). But, I don't see that being used in the "return" code.
Is there other code that reads (0x4006) to know to return to 0x0020018F (which would be the next instruction after the JP at 0x20018D)?
