The title explains everything, this program stops people from booting up any startup file located in a floppy disk unless they have a magic word in the first line of the file. This is done by monitoring all the disk drives attached to the computer and checking if someone plugged in a disk, if someone did it'll search for a startup file inside the disk. If the disk has a startup file the computer will read the first line of it to see if the magic word is pressent. If it is, the computer will unlock, allowing you to type anything and/or edit files in the computer. If the computer doesn't find the magic word it will erase the startup file, preventing you from using it

Ok

Edit: Actually that's easy to fix, just have to check if the variable key == nil or if it is not alphanumeric

Edit2: What exactly do you have into the disk file? Just want to know

[FUCKCOMPUTERCRAFT!"£]

I'm not really wanting to release it, but I will test any new version you produce...

Nope, maybe it's a char that the computer can't read....

Nope not like a letter from a different language etc...

[Heracles421]

Ok, changed a bit the read function, try it
Also uploaded to pastebin

[FUCKCOMPUTERCRAFT!"£]

Just used you're pastebin upload. My method still works but has a different error...

"assertion failed!"

[Heracles421]

Agh, almost get it, I only need to change the assert error and it's done

Try it now

[FUCKCOMPUTERCRAFT!"£]

Did you upload it to pastebin? As I get the same error..

[Lyqyd]

Is this a ROM modification? If it's not, all they have to do is shut the computer down first.

Correct also, didn't think of that (embarrassed face)....

[Heracles421]

Nope, it doesn't modify the ROM, and I know that if you shut down the computer it can be bypassed. There is no other way of stopping the disk boot up other than modifying the ROM itself, but at least this helps in some way

Maybe I can try to stop you from shutting down the computer....

How and then yet again there is still my method
