- It would not crash under new OS versions, because it would only use a few
- bare essential routines like Forbid() and Permit().
- And whats the point about booting got to do with the price of fish?

- Depends what you mean by bogus displays.
- NTSC users would loose a portion of the screen due to the fact that the
- NTSC screen can't display as many lines at a PAL screen.
-
- Easy enought to avoid, just :
-
- 1.. Write another version where the graphics are kept withing a smaller
- area on the screen.
-
- 2.. Write a just an NTSC version, so all the lucky PAL owners have a chunk
- of screen missing (*not big OR clever CINEMAWARE*).
-
- >d) risks hardware damage with things connected to the serial or parallel port.
-
- How could it *dammage* hardware?
- Your not one of them guys that think that some viruses write to the disk
- label are you? :)
-
- >Ah, yes.. that's my experience with the creations from "demo coders".
- Are you sure?
