- 1. An introduction
- ==================
-
- These two programs were written mainly for PAL users who are tired of
- "flickering" 50Hz displays. As most people know a 60Hz display looks much
- more stable than a 50Hz display. Sadly enough, European users are stuck with
- this 50Hz display. Or are they ?
-
- Workbench 2.0 holds a preference editor to change the mode of the Workbench
- screen. Provided he has a ECS Agnus (also called Big Agnus) installed in his
- Amiga a PAL user can select an NTSC display mode for the Workbench. Great!
- But what about the other screens. As soon as a custom screen opens the
- refresh rate pops back to 50Hz, PAL. Shucks!
-
- Time to check out AmigaToNTSC and AmigaToPAL. AmigaToNTSC will patch the
- Graphics library so it will think you have an NTSC Amiga. AmigaToPAL will
- patch it to think you have a PAL Amiga. Custom screens will open in the mode
- you selected. Problem solved.
-
- For people who own an A4000 with the AA chip set there are two special
- versions of these programs: AmigaToDoubleNTSC and AmigaToDoublePAL. These will
- patch Graphics library so it will open the double version of the NTSC or PAL
- monitors. This will offer you enhanced mode promotion to the display type of
- your choice, instead of the IControl preferences switch.
-
-
- 2. Usage
- ========
-
- For PAL users who want a stable 60Hz display for all screens:
- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
- Use the ScreenMode editor to select NTSC:Hires or NTSC:Hires-Interlace
- display mode for the Workbench screen (make sure the 'NTSC' monitor is dragged
- into your Monitors drawer). Then drag 'AmigaToNTSC' into your WbStartup
- drawer. If you now restart your Amiga it will behave like an NTSC machine.
- Switching temporarily back to PAL can be achieved by running AmigaToPAL.
-
- On Workbench 3.0 and the AA chip set the screen mode to 'DBLNTSC:High Res
- No Flicker' and drag 'AmigaToDoubleNTSC' to your WbStartup. This will open
- all screens that don't specify a monitor in the Double NTSC mode.
-
- For NTSC users who want a 50Hz display:
- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
- The AmigaToPAL program is useful for NTSC users who whish to run programs
- which require a PAL screen. They should simply run AmigaToPAL before running
- one of these programs.
-
- NTSC users can of course also follow the procedure decribed for PAL users
- above, with PAL and NTSC switched. But I can't think why they should wish to
- do so.
-
-
- 3. Known problems
- =================
-
- - SysInfo gives wrong results when run on a PAL Amiga patched with
- AmigaToNTSC. The machine is considered slower than it is. It seems that
- SysInfo times using the vertical blank and expects a 50Hz refresh rate.
-
- - Because this program patches GfxBase it may not be compatible with future
- versions of AmigaDOS (Kickstart 4.0 ? :-).
-
- - You can only reliably save a setting in the ScreenMode preference editor
- if your Amiga is _NOT_ patched. So if you want to save a new ScreenMode
- setting run AmigaToPAL first if you have a PAL machine, AmigaToNTSC if you
- have an NTSC machine. Failing to do so will result in a wrong setting
- being saved.
-
- - Don't try putting these programs in your user-startup. That doesn't seem
- to work. Drag them to your WbStartup.
-
- As always, I hope you find these programs useful!
