- I was under the impression that Fabio was saying SVGA was useless for games,
- full stop. In which case, I'm arguing that VGA-style chipsets can be used very
- easily to write good games (both texture mapped, and scrolling).

- No, I thought exactly what you just wrote. I said coders used the copper to get
- around speed restrictions - that's what it does.

-
- Yeppo - pretty complex.. :)
-
- >No "copper hacking", no "slow API games".
-
- So somebody hurry up and get a standardised library out to help with this...
