Well, here's my newest reverse me. Actually, its kinda reversed already. Guess whut that means you have to do. Thats right, put it all together and make a working PE file. It shouldnt be too hard for seasoned reversers and will be a good learnig experience for the rest of us.

Things you'll need to do:
Add/Create the Dos Stub/PE Header
Figure out which section is which
Put it all together, and make it run

As a hint: have careful with the data section... which is it's real RVA? :P
You can find 00 20 40 00 at the start of it.. but if you study a bit the code section you can find:

00401400 |. 6A 00 PUSH 0
00401402 |. 68 38304000 PUSH Loader_B.00403038 ; <- :O
00401407 |. FF75 F4 PUSH DWORD PTR SS:[EBP-C]
0040140A |. FF75 08 PUSH DWORD PTR SS:[EBP+8]
0040140D |. E8 FA000000 CALL Loader_B.0040150C
00401412 |> 5F POP EDI

which look a messagebox call :P
