Note to self

[Joe]

If you're reading this and you're not me, you're not self. But anyhow, I'm going to try installing Ubuntu on my laptop, so I'm "backing up" all the useful code I have written right now.. which is nothing but this:

Code Select Expand

[ORG 0x100]

; strings
cdkey db '0000000000003','$'
valid db 'Valid!',0x0d,0x0a,'$'
invalid db 'Invalid!',0x0d,0x0a,'$'

MOV ECX, cdkey
CALL IS_VALID
CMP EAX, 0
JNZ Valid
JE Invalid

Valid:
  MOV DX, valid
  JMP Print
Invalid:
  MOV DX, invalid
  JMP Print
Print:
  MOV AH, 9
  INT 0x21
Exit:
  MOV AH, 0x4C
  INT 0x21

IS_VALID:
  MOV EAX, 3
  MOV ESI, ECX
  MOV EBP, EDX
  XOR ECX, ECX
Top:
  MOVSX EAX, BYTE [ECX+ESI]
  SUB EAX, 0x30
  LEA EDI, [EAX+EAX]
  XOR EDX, EDI
  ADD EAX, EDX
  INC ECX
  CMP ECX, 0x0c
  JL Top
  XOR EDX, EDX
  MOV EDX, 0x0a
  DIV ECX
  MOVSX EDX, BYTE [ESI+0x0c]
  MOVSX EDX, DL
  ADD EDX, 0x30
  CMP EAX, EDX
  JNZ Fail
  MOV EAX, 1
Fail:
  MOV EAX, 0
RET

Why don't you drop that in a zip folder on a thumbdrive or something? Or PM it to yourself? :P

I knew this was a Joe topic when I saw it on the newest reply.

Thumbdrive is NTFS. Laptop is Win98. And I wanted someone who was bored enough to realize the code was broken and wanted to fix it. :)

You do not know how many "note to self" topics there are in the members' forum.

Why is your thumbdrive NTFS? It's supposed to be FAT32 so you can just pull it out without worry of having to eject it...
