我正在开发一个破解版，我一直在做一个特定的比较，我希望你能帮助我过去（其中之一）。这是我所知道的，相关的代码片段如下：
表格中需要 19 位数字
xxxx-xxxx-xxxx-xxxx（无非数字字符）。这些是以前的检查。看起来 19 位数字相加，加上 10 位，除以 4（右移 2 位），然后与堆栈上的某个值（我无法确定）进行比较。
你能帮我绕过CMP最后一行吗？
编辑：不允许NOP任何指令，需要找到序列号。
CODE : R9 是用户输入的 19 位字符串 增加了整个功能
var_18 = byte ptr -18h
var_8 = qword ptr -8
sub rsp, 18h ; Follow four lines check for 19-digit user entry

原始块：

; Likely begins set of first checks on actual digits
movsx ecx, byte ptr [r9+3] ; Get 4th digit
add r11d, 1 ; Loop counter, loops 4 times, for each set of digits
add ecx, eax ; Set ECX to 3rd digit + 4th digit
movsx eax, byte ptr [r9+1] ; Set EAX to 2nd digit
add rbx, 4
add ecx, eax ; Adds 2nd digit to total
movsx eax, byte ptr [r9] ; Move first digit into EAX
add r9, 5 ; Moves to 2nd set of digits
add ecx, eax ; Adds 1st digit to total
add ecx, r11d ; Adds 1, for a total of 10
nop
nop
mov [rbx-4], ecx ; Added four digits stored here too
add r10d, ecx ; R10d becomes our added ECX value from above
cmp r11d, 4 ; Loop counter check
jb short forLoopCheck
shr r10d, 2 ; shifts right r10d by 2, AKA divides by 4
mov ecx, edx
lea rax, [rsp+18h+var_18] ; var_18 = -18h
xchg ax, ax ; A NO OP
cmp [rax], r10d ; Compares right shifted 2 value to whatever is in RAX
