| jB_ 30. Jun 2007 | Nice crackme, like the first one. It is a good starter, give us something harder next time :) |

| opcode0x90 Author 02. Jul 2007 | Glad you like it. :) Perhaps next time I will write up an unpackme, so stay tuned. ;) If its possible, do submit your solution. There is more than 1 way to solve this crackme. |
| BUBlic 26. Jul 2007 | Oh no! No pizza either! Nice one though, but Difficulty: 1? |
| alex_ls 03. Aug 2007 | There's very nice crackme, but resolving this staff i found it more complicated than i have expected (difficulty: 1) |
| opcode0x90 Author 05. Aug 2007 | GJ man. Have I under-rated this crackme? :/ The whole thing is very straight-forward. I made no attempt to obfuscate the VM engine or anything similar. The only thing hard should be the hashing algorithm. |
| cryostat13 15. Aug 2013 | hi Bargest can you share source dissasembler? |
| Bargest 19. Aug 2013 | Yes, I can. Check PM. |
| Bargest 19. Aug 2013 | For everyone, who wants to see this... "disassembler": https://www.dropbox.com/s/yt6075l5hj7i5z9/Source.cpp |
| barun 16. Oct 2014 | Good one. Indeed, it should be the first one to try before checking other VM crackmes. My solution includes a disassembler in python for Imm Dbg. |
