Hi there. I am working on a scheme to bypass the sentinel protection on an older bit of development software (16-bit) I use at both uni and home. Obviously if anybody else needs the dongle I can't work on my stuff so I want rid. I got the suggested software (WDASM and SoftICE) and read through Crackz tutorials and set to work. I have limited asm knowledge but I'm trying to improve that with the linked tutorals. I couldn't find the 7242 string any of the dll's so I set the old bpio 378 and waited. It broke in one of the main dll's several times but seemed to loop the same few addresses for most of them. I also found the DeviceIoControl string in one of the dll's and flaged that but that seemed to break just at desktop (maybe win98 testing port or something). So I gave up on that avenue. Now I'm at a juncture and could do with some advice. I thought getting IDA and applying the sig files to it may help (if that works for 16-bit files) if not I'm a bit stuck. When I load the file with symbol loader I get the message 'error no debug information available' and WDASM is a bit touchy if I try and adjust a bit of the code. Could you give me a few hints on how to continue.

yours sincerely

Hi,

Sentinel Super Pro.

Are you sure its Super Pro? 16 bit is old stuff.

Hints :
make sure it is Super pro.
Search for 16 bit Sentinel stuff.
Can it be emulated?
If not then whats next?

Name the proggie if you run into more trouble.

Sentinel can be reversed, many have done it.

Peace, Woodmann

You are 100% correct Woodman.

It could very well be a standard sentinel Pro.

I remember the early ones about 3-4 inches in length.

It definately a super pro, I have the dongle in front of me. I tried ida with the super pro sig files but to no avail. It didn't find any instances even though that is where softice breaks. The program I am working on is t*st-point. Any further advice would be grately appreciated. I was going to include what I think is the offending dll for your perusal but it is too big. You can download it from the website with the same name (The upgrade is actually the whole program).

Definitely Sentinel and definitely 16-bit!

The Sentinel code you are looking for is in tpmain.dll and is easily "fixed" - especially if you have the dongle.

This app will also run with a CryptKey license.
