- Ok, everyone, this is what I have found out about games using these
- high Falcon030 resolutions...
-
- If I'm incorrect, please feel free to post. :)
-
- I'm clear to that fact that games can use almost any resolutions, but
- some would be better than others for certain situations.
-
- These have been the resolutions that people have suggested that might
- be the best to use for games:
-
-
- 320x200
- 384x240 overscanned
-
- 384x240x256 = 92k (x2 for double-buffering = 184k)
- 384x240x65536 = 184k (x2 for double-buffering = 369k)
-
- There would be no flicker on a TV because this resolution is not
- interlaced.
-
- 1 Meg would be required to produce games in this resolution.
-
- 320x400
- 384x480 overscanned
-
- 384x480x256 = 184k (x2 for double-buffering = 369k)
- 384x480x65536 = 369k (x2 for double-buffering = 737k)
-
- There would be hardly a flicker on a TV even with this resolution
- interlaced.
-
- 1 Megs would be enough to produce games in 256 color mode, though 2 Megs
- may be needed for the TRUE color mode.
-
- 640x200
- 768x240 overscanned
-
- 768x240x256 = 184k (x2 for double-buffering = 369k)
- 768x240x65536 = 369k (x2 for double-buffering = 737k)
-
- There would be no flicker on a TV since this resolution is not
- interlaced.
-
- 1 Meg would be enough to produce games in 256 color mode, though 2 Megs
- may be needed for the TRUE color mode. Same as 384x480.
-
- But I'm curious to know how the graphics will look in this resolution...
-
- 640x400
- 768x480 overscanned
-
- 768x480x256 = 307k (x2 for double-buffering = 614k)
- 768x480x65536 = 614k (x2 for double-buffering = 1.2 meg)
-
- There may be a small flicker when using graphics on a TV--no one really
- knows how bad it may be. Any developer care to test it?
-
- 1 Meg MIGHT be enough to produce games in 256 color mode, though at
- least 2 Megs would be required for the TRUE color mode.
-
-
- I am NOT sure if 320x480 (normal), 320x240 (line-doubling),
- 640x480 (normal), and 640x240 (line-doubling) can be displayed on a TV
- or a SC1224 monitor OR if they can be interlaced. The information
- from John Townsend makes it unclear.
-
-
- It is CLEAR that 2 Megs would be more appropriate as the minimum amount
- shipped with a Falcon030 if Atari wishes to make the Falcon030 an
- excellent game platform.
-
- I believe Commodore was thinking this when they began shipping the
- Amiga 1200 with 2 Megs.
-
- It is true, that the majority of these resolutions could be used with
- only 1 Meg of memory, but there would be little room for the programmer
- and the sound would be pretty bad.
-
- If Sam asked me, I'd ask him to consider shipping the Falcon030 in these
- configurations:
-
- Falcon030/no memory/no hard drive...plug in as much as you want.
-
- Falcon030/2 Megs memory/
- no hard drive......................minimum amount.
- Falcon030/2 Megs memory/
- 65 Meg hard drive..................minimum amount with hard drive.
- (the reason I'm leaving the hard drive 65 Megs is because Atari probably
- made a deal on them. The drive probably should be around 85 Megs.)
-
- Falcon030/4 Megs memory/
- 65 Meg hard drive..................middle amount.
- Falcon030/14 Megs memory/
- 200 Meg hard drive.................high-end machine.
-
-
- I understand that the Falcon030 will be used for much more than
- just games, but what else could only use 1 Meg?
-
- Also, let's take a look at the SNES and Genesis resolutions just
- for the sake of having one up on these systems:
-
- Super Nintendo: 512x448x256 = 229k
-
- Genesis: 320x224x64 = ?
-
- Anyhow, you can see that the Falcon030 could forget about 320x200.
- The resolution of 320x400 MIGHT be able to compete when overscanned.
-
-
- But it would be best to try to get a leap on the other machines by
- using the 640x200 or 640x400, no?
-
-
-
- Thanks.
