Zak, what you tell me is intriguing. The error you're getting must be based on something that does not happen on the computer I was trying Vizcacha from, since I did try the program under XP's DOS emulation. I will need to send you an auto-debug version so that it reports more details on the error, as I cannot generate it from here. Also, I have had to return the computer I had been lent, so that make take some days. In the meantime, please continue to look for bugs or give ideas.
I also realized of a problem while I was about to fall asleep yesterday night. I protected the menus against keyboard action, but not against the mouse! Please test both separately and tell me what happens, as I can't test Stunts for now. It is very easy to fix this problem, but I need a computer other than at the cyber café. To begin, I can simply get Vizcacha to disable the mouse completely and then with some little more time, I can make a neat protection against menu selection with that device.
It is true. Vizcacha writes the data at the end of the RPL file. Old VC 1.0 would append 30 bytes. VC 1.1 appends a fixed-length 32 bytes field. You can use this info to calculate the RPL time. I left the pipsqueak name not-encrypted on purpose. VC will know if it is modified and will say it is, but if I encrypted with the same code as the rest of the data, the encoding may be easier to make out. That's why I left it visible. Anyway, even if the pipsqueak changes the name, the rest of the data is the important thing, as you know who you receive the RPL from. Still, I can strengthen the encryption system easily. I haven't learnt PHP, but I guess an implementation of VCV only (the verifier) must be easy to accomplish. It would be very important that the decryption code could not be reached from online. I know that is OK with PHP.
What I'm most concerned about is what you say about it always reporting no replay handling was used. I guess what is happening is this: VC 1.1 is running properly and therefore assumes you were unable to use RH. You use Stunts fully with the mouse so you have not even had a problem with VC to do RH. If you tried to do it with the keyboard, you would see you would not be able to. Please let me konw if I'm right. If that is the case, all I have to do is fix the mouse problem.
Thanks very much for testing
I will continue to work on it as soon as I can
