Delete Branch "%!s(<nil>)"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
There seems to be a huge number of players who are interested in this game.
I tried to take a look at the game, but not sure how their dongle works.
Currently I just hook
nbamUsbFinderGetSerialNumber, but no avail. I can only get Dongle Error 2. In the disassembly, I see that it will look for a removable drive, then read 256 bytes from a file whose file name is calculated from the returned serial number and finally perform some calculation, I wonder how would this dongle check work?Hm, interesting. I haven't seen a game actually try to read data from the drive before. I don't have the game so I can't say for sure what the mechanics of it are. I'd be interested to take a look, but since I don't have the game, I can't really do anything.
I find these around
nbamUsbFinderGetSerialNumber, and the serial number returned is used subsequently, so I assume this is what the game is trying to do with the dongle, not sure whether they are actually related.Please don't link to data here, no matter how public it is.
As for the code snipits, I'm not sure. It's probably doing something fairly simple. I'll look into it shortly.
Oops, sorry for that.
In one subsequently called function, I find constant 0x100000001B3 being used, so looks like this algorithm is used, there's definitely some hashing going on here, but I am not familiar with these.
I've never seen that before in my life... I'll have to do some more testing. Currently I can't even get the game to get past the System Boot Error screen.
Oh, this issue seems to be caused by client type. The game has a terminal(live monitor) mode and pcb mode, which seems to be related to something called
bootParam.bin.I don't know what this file or something should look like, but if you search for string
CLIENT_TYPE, you should be able to find the function for parsing this parameter which determines client type. Therefore currently I just patch there, 1-4 seems to be valid values.Speaking of client type, from teknoparrot, it seems that two computers (one live monitor) is required.
Closing this because lol
