- SOME COMMON PROBLEMS/FAQ
-
- Q. Where can I get coolz warez romz?
- A. Go away.
-
- Q. What's an Atari? How do I use it? What are disks? How do I use those? What
- kind of DOS is this? etc etc.
- A. Well, I can't teach folks everything about an Atari 8-bit computer here,
- but luckily there are some guidelines on the net. Try Ivo Van Poorten's
- page at:
- http://pmwww.cs.vu.nl/home/ipoorten/Atari.8bit.Homepage/index.html
-
- Q. I get something about MFC.DLL or MSVCRT.DLL not found.
- A. This should be rare (these are common DLLs used by many Microsoft products,
- and so are often already installed). However if you see this problem download
- this file: http://activex.microsoft.com/controls/vc/mfc42.cab. If you have
- Internet Explorer it can install it automatically. If you don't, get the
- Powertoys Cab Viewer at
- http://www.microsoft.com/windows/downloads/contents/powertoys/w95cabview/default.asp
- and install it (it's quite small and useful besides). Not including these
- files by default makes Atari800win much smaller and easier to download for
- the majority of people who already have them. This should never happen in Win98.
-
- Q. How about not found on DINPUT.DLL, DDRAW.DLL, DSOUND.DLL?
- A. You do not have DirectX installed correctly. Don't even think of e-mailing
- me telling me you do (as often happens). I repeat, you do not have it
- installed correctly. Re-install DirectX 5.0 or higher if you have Win9X, or
- install Service Pack 3 or higher if you have NT 4.0.
-
- Q. In stretched DirectDraw windowed mode, my screen looks a little "fuzzy".
- A. Bone-head graphics card tricks. This is becoming more common on 2D/3D card
- combinations. Since I am asking it to stretch the bitmap to 2X original size,
- the card does foolish and unrequested things like bilinear filtering even though
- the source and destination surface are both 2D. Some cards allow you to turn this
- off, with others you will just have to use GDI mode, which always works correctly.
-
- Q. I can't use my joystick under NT.
- A. That's right, you can't. Can't use it anywhere else under NT either, right?
- Well there you go. There are some custom drivers that allow this, but they
- aren't DirectInput compatible. Wait for NT 5.0.
-
- Q. Why can't I save a game on a compressed (DCM, gzip) disk?
- A. Compressed disks are automatically inserted as read-only. If you want to save
- a game or write to a compressed disk, decompress it first and insert it as a
- regular ATR.
-
- Q. How do I get an EXE or COM file to work, one without a disk?
- A. A new feature in version 2.5 allows you to load these directly (use the Atari,
- Load EXE menu option). It will not work with all executables however. If it
- doesn't, use the method below:
- Copy the file to a directory on your hard disk without a lot of other files
- present. Assign an H: device to that directory by using the Atari/Hard disk
- menu. Boot the Atari with a floppy in D1:, then load the program from DOS
- using the H: device, ie "H1:PROGRAM.EXE". The usual load command in Atari
- DOS is "L".
-
- Q. What's a "BIN" file?
- A. It could be either an executable (as in the point above) or a cartridge. Try
- loading it from DOS first, if that works, it's a regular EXE, and you should
- rename it to EXE. If it works as a cartridge rename it as .ROM to make things
- easier next time around.
-
- Q. Why don't 5200 carts work in a 130XE/800XL/whatever, or vice versa?
- A. Because they were made not to do that originally.
-
- Q. It doesn't run at 100% Atari speed.
- A. At this point, any Pentium machine should be able to get 100% speed using a
- low res (320x240) video mode, possibly without sound depending on the sound
- card. If you are getting REALLY slow response, the most common problem is
- DirectX drivers that just aren't very good. There are some old video cards
- out there that just refuse to refresh the screen more than 30 times a
- second, and I'm trying for 50/60 times. Try setting refresh rate = 2 in
- the hardware menu (gives you 25/30 frames a second). This doesn't hurt the
- emulation, just updates the screen less frequently.
-
- Q. I have a 5Ghz Dominator Extreme system, and when I run full speed, it doesn't
- run 42 times Atari speed! What's with that?
- A. First, the priority of Atari800win is not to run as fast as possible, but to
- be as accurate as possible. Second, the most limiting factor in trying to run
- very fast as an Atari is screen updates. If you want to really crank the
- speed up, set your refresh rate to 5 or higher and THEN set to full speed.
-
- Q. My sound makes thumping noises.
- A. The emulator is running too slow to keep up with the sound buffer generation.
- I have seen this happen because of poor sound cards ("SoundBlaster compatible"),
- slow display hardware, or just plain slow computers. Anyway if you aren't
- running at 100% speed consistently sound will never be quite right.
-
- Q. My sound makes high pitched hum noises.
- A. Increase the "Pokey update divisor" on the Sound menu. This controls how many
- times sound is computed. If it is set to 1, the Atari computes sound up to
- 312 times every 1/50th of a second. Set to 2 this drops to 157, set to 3 it
- drops to 104, etc. The only adverse affect to increasing it is games like
- Berzerk will sound worse when using digital speech. The HIGHER your sample
- frequency, the LOWER you can set this value.
-
- Q. Program XXX doesn't work.
- A. Things to try: 1) Try it under a different OS/DOS combination. 2) Cold boot
- the emulator by hitting Shift-F5. 3) Make sure BASIC isn't inserted for games
- (unless they happen to be in Basic of course). 4) Perform appropriate
- incantations over computer. 5) Try booting a full disk image with the program
- on it.
-
- IMPORTANT: Some games require write access to the disk! (Alternate Reality for
- one). If a game isn't working, decompress the image and make sure you aren't
- using it off a CD-ROM, so you will have write access!
-
- Q. In 800x600 mode, I see strange and mysterious things at the edge of the
- screen.
- A. Atari800Win allows you to see the _complete_ overscan area when in 800x600
- mode. Most folks with Atari computers never had a chance to see this; the
- average TV is nauseatingly clipped both vertically and horizontally (I see
- the light shining on a few of you who now realize you are missing about 30%
- of the screen area on TV broadcasts). Anyway, since it was very rare to see
- the overscan area, many programs make mistakes in this part of the screen.
- The designers figured nobody would see it anyway (or maybe they didn't see
- it themselves).
-
- Q. I have a laptop....
- A. You're probably SOL. Laptops refresh their screens very slowly to conserve
- power (even when plugged in). This causes DirectDraw to pause for long
- periods when drawing the screen. GDI mode might even be faster. Laptops are
- very poor game machines, try it on a desktop machine.
-
- Q. I got a DirectSound/DirectPlay/DirectDraw error! Halp!
- A. When you get one of these, it may be just because your DirectX drivers don't
- support what you want to do - the particular video mode, sound options, etc.
- I took pains to try and make sure Atari800Win always backs out of these
- gracefully, so hopefully nobody will get a crash as a result. When a DirectX
- error appears, try whatever you were doing once more, if the same error
- appears, your drivers probably don't support that and you should revert to a
- different video mode/different sound settings. If you really believe you
- should be able to do whatever it is and it still doesn't work, e-mail me with
- the particulars (and don't forget to write down the error that appears in the
- dialog box).
-
- Q. The program says the Atari computer died!
- A. Yep, this happens. It basically means the Atari just tried to execute an
- instruction that doesn't exist on the computer. Most likely a real Atari
- would have locked up as well. A *common* cause of this is having BASIC
- resident with programs that don't like it, or vice versa. Another common
- cause is running on the wrong platform. Although it still can happen these
- days it is pretty rare that the emulator actually broke something that should
- run ok under the selected machine/OS.
-
- Q. Never mind that dialog box stuff, it just crashed, as in GPF.
- A. Atari800Win is extremely stable at this time. If a GPF occurs, please try the
- same operation again (after starting back up) and see if it is reproduceable.
- If so, hit ctrl-printscreen with the GPF dialog box up, and mail it to me.
-
- Q. Disaster! The program crashes when I start it and I can't get to the menu
- to reconfigure the disk drives!
- A. There is a menu option under "Misc" labeled "Clear all settings". Use that
- menu. Head the warning: only do this if you are really stuck, as it will clear
- every option you have set in Atari800Win and start over. But it should fix the
- problem in the process, you'll just have to re-enter you ROM locations etc. If
- you are completely unable to boot the emulator, it should ask you (after you
- kill it once) whether you want to clear your settings when starting up. Do so,
- and everything will be reset to defaults.
