- BTW, this remind me of what we talked earlyer: having CBM include
- an OSSleep() command... it would request all device to sleep.
- This would be used in an env like portable amiga to shut down
- inactive device... And so, why not take over the machine when its
- sleeps?
-
- Also, is there a way to write a reset function that ask all amiga
- device to shutdown? I really hate when I press amiga-amiga-ctrl
- and my amiga HD get trashed, I want a softreset. From what you say
- about OS interuption its not possible... :(

- : >There you go again, avoiding the question because you can't answer it.
-
- : I can answer it. But then you will reject my idea of "great game".
-
- one key to the discution is here... YOU want one type of game and
- probably dont care about the game gliters... other do, beleive it or
- not. And 'stunning' FX on low power machine with an OS not designed
- to take advantage of its HW is not really possible to acheive.
- Why force all to make your kind of game and demo?
-
- : >Whether a hw-coder tried or not is irrelevant.
-
- : No, it isn't. You argue that the OS is bad (for game programming) because
- : otherwise there would be great games that used the OS. Don't you think there
- : could possibly be other reasons ?
-
- There are so many reasons... Some good some bad (Like "I kow the 680x0
- and I read the HW manual, lets make a game"). good reason "1.0 suck,
- 1.1 suck, etc.. 3.x suck for high performance gfx using the amiga HW"
- if you want to do something right under any of those OS version (ALL) you
- need to Alloc the peice of HW and bang it. Many games dont need that
- efficiency, other dont... why try to generalize so much.
-
- : >Not rubbish. Do you think that hw-programming means you can't support
- : >faster machines?
-
- : No. I think that faster machines are not supported by c0d3rz. That's a difference.
- : The reason is that c0d3rz base decisions on mere assumptions (like: "self-modifying
- : code isn't going to break with caches" or "blitter-nasty will stop the CPU until
- : the blit is done").
-
- Then tell those people that self modifying code break if you dont flush
- the cache, tell that you need to wait for blitterfinish even when the
- blitter is in nasty mode (even so that on a 68000 you can get away with it)
- BTW, CBM didn't think it was interesting to offer fastram in the A1200
- standart... so some games are designed with this in mind. chip only.
