Syscall %247 GetKeyWait from Graph 35+E II OS 3.10
|
|
|
|
Disassembly objective:
|
|
Understand the return-to-menu mechanism and hidden functions of GetKey().
|
|
|
|
Discovered RAM memory:
|
|
|
|
This group of variables is related to an obscure long-jump-based scheme that
|
|
manages global state for GetKeyWait. Check "GetKeyWait_Dispatcher.txt" for
|
|
more details.
|
|
0x8801b62c: setjmp_buffers (jmp_buf[2])
|
|
A datable with two jump buffers of 80 bytes each.
|
|
0x8801b6cc: setjmp_buffer_index (u8)
|
|
Index into the jump buffer table at 0x8801b62c.
|
|
0x8801b6cd (u8)
|
|
Controls the setup of a setjmp() at the start of GetKeyWait_Main.
|
|
0x8801b6ce (u8)
|
|
Copied to 0x8801b6cd in state #4 around <80089e38>.
|
|
|
|
0x8801340c (i8[16])
|
|
0x8801341c (i8[16])
|
|
Two arrays of 8-bit integers. Seen used with a common index. Value seen
|
|
tested >= 0 using cmp/pz.
|
|
0x88013464
|
|
An index into the two arrays above.
