flcksr on 2024-07-30 19:42: Super easy, unpack upx then in x64dbg at 00401558 change it to jmp instead of je and you're done
CrYP70NYM on 2024-07-31 00:43: @flcksr Yep thats how you crack it!
perXhide on 2024-07-31 15:39: I tried changing MOV EAX, 1 ; Set return value to 1 in checkCdRom function
Helel on 2024-08-01 10:35: Hi. I'm so new to this field, I just found out what packing is. Could I unpack with Ghrida?
Sir_Zed on 2024-08-01 17:22: @Helel UPX is just for making files smaller not for protection. To unpack it, just use: :upx.exe pr.exe -d ( u need to install upx ofc).
For other packers, try DiE or PEiD. They can spot most common ones. After that, a quick Google search will show you how to unpack them.
Ofc, if you wanna get fancy, you can use a debugger to unpack UPX manually. Lots of tutorials out there for that.
Good luck!
loadlibrarya on 2024-08-02 06:40: unpack - bytepatch the cdrom check - cracked!
also the game rotates the camera too fast (multiply by deltatime?) + the left and arrow keys are inverted
Lucas0001 on 2024-08-02 22:14: 1. Unpack UPX with CFF Explorer Suite
2. Just skip the CD ROM check
3. Enjoy the maz
Doubtful on 2024-08-05 22:04: Unpack with UPX then skip a checking part for example with changing JE to JMP or filling the warning jump with NOP's.
Irval on 2024-08-09 16:03: 1. Unpacked UPX
2. Patched .text:0040150C:00401557 to nop's (0x90) - You can skip this step. I just wanted to cut out the verification call on the CD.
3. Patched .text:00401558 je to jmp
PL45M4 on 2024-08-12 01:40: D3DX9 is required to complete this crackme. I was able to download the runtime from here: https://www.microsoft.com/en-us/download/details.aspx?id=8109
survivalizeed on 2024-08-14 15:09: Nice game :). For anyone who wants to learn reverse engineering better, I highly recommend to NOT use UPX here. Do it manually so you learn more!
iaakanshff on 2024-08-18 16:27: Oh, it was an easy one, all i did was just unpacked and then patched the jnz instruction at 00402329 with jz. Then patched the jz instruction at 00402364 with jnz. The goal was to return 1 from the CheckCDRom function. By the way, i used ida Finished.
c0mrade on 2024-08-19 15:25: begginer here, whats the pw for the zip? after all i need to access the file to crack it, right?
