- Well, apparently, there are more than compatibility issues involved. On
- csa.games, Chris Green mentioned that getting 2x or 4x bandwidth out of
- AGA is not "easy". ie. The only way to get fast screens for most
- hardware programmers is to use the OS. I *love* it, all these Kewl
- D00ds talking about how fast hardware hacking is... guess what, it turns
- out it's SLOWER if you use those reverse engineered AGA hardware refs,
- since most of them don't mention anything about alignment restrictions
- and enhanced fetch modes. I gotta laugh.
