The following information is based on the 1.x version since the 2.x was not available at the time I figured this out.
|
||
|
|
But I guess it will work on that versions also.
|
||
|
|
|
||
|
|
|
||
|
|
How it works
|
||
|
|
============
|
||
|
|
|
||
|
|
Basically, VE is a compression tool. It lets you manually compress files and adds the extension `.vem` to them. This
|
||
|
|
extension is associated with the VE Decompressor. So if you double-click a `.vem`-file, it will decompress it and
|
||
|
|
launch it right after that.
|
||
|
|
|
||
|
|
While this works fine for single documents, it doesn't work for a program consisting of many different files as only
|
||
|
|
the file you click is automatically decompressed and not all together. Also it doesn't recompress a file after use so
|
||
|
|
it's not really more comfortable than using a regular compression program.
|
||
|
|
|
||
|
|
The program activates itself if it detects a SONY USB drive based on its PnP-ID, like `USB\Vid_054c&Pid_0241`.
|
||
|
|
|
||
|
|
|
||
|
|
Hacking the tool
|
||
|
|
================
|
||
|
|
|
||
|
|
The latest version, `VirtualExpander_v24.exe` contains the following strings hardcoded in Unicode starting at position
|
||
|
|
`0x39a2c` (VendorID `054c` = *SONY*):
|
||
|
|
|
||
|
|
* `USB\Vid_054c&Pid_0241`
|
||
|
|
* `USB\Vid_054c&Pid_0242`
|
||
|
|
* `USB\Vid_054c&Pid_0243`
|
||
|
|
* `USB\Vid_054c&Pid_02a5`
|
||
|
|
* `USB\Vid_054c&Pid_02a7`
|
||
|
|
|
||
|
|
To make it work with ANY USB drive, just get the ID of your drive:
|
||
|
|
|
||
|
|
1. go to *Control Panel* => *System* => *Advanced* => *Environment variables*
|
||
|
|
1. add a new **System** variable `DevMgr_Show_Details` with the value "1"
|
||
|
|
1. <kbd>OK</kbd> your way back to the Desktop
|
||
|
|
1. open the Device Manager (make sure you closed the "System"-Control Panel before!)
|
||
|
|
1. find your USB drive in the *USB* group and right-click => *Properties*
|
||
|
|
1. find the ID on the new tab *Details*
|
||
|
|
|
||
|
|
Now use your favorite Hex-editor and overwrite one of the SONY IDs with the PnP-ID of *YOUR* USB drive. That's all!
|
||
|
|
|
||
|
|
(The v1.3 has 3 IDs starting at position `0x31950`.)
