...And why? I am playing the game DELIVERANCE on my US NTSC A2000 system, and the bottom of screen where my health and number of lives are displayed is cut-off. I am sure it is due to the game being a PAL. (See the info about the game here:
http://www.lemonamiga.com/games/details.php?id=315)
My question is, that how can I switch between PAL and NTSC? (My system came pre-installed with a KickROM 2 and 1.3 switcher). And why PAL games do this?
Thanks!

First off, you need a 1MB Fat Agnus in order to switch between modes on an Amiga. Assuming that's in order, you can flip between modes by soldering a switch between Jumper 102 or using a program such as Tude or Degrader after Workbench has loaded.

I remember bring able to choose between NTSC and PAL in the boot menu or was that only for the 1200/4000?
There are advantages and disadvantages between the two formats as far as Amiga gaming is concerned. You have the advantage as outlined by the poster where you have more realestate on the screen for graphics to go but PAL also runs a little slower due to the 50Hz vs 60Hz scanning frequency. Since PAL is(was) the standard for Australia, I know of a friend how did the mod to be able to switch between the two modes on his Amiga 500. He swears some games did receive a slight speed up.
At the time, I just remember being glad we had PAL so it meant we could play all the games from around the world :)

PAL has a higher resolution, sounds like your extra pixels are off screen taking a siesta.

Yeah, but only because they came with Kickstart 3.x. The OP indicated he only had 1.3 and 2.x.

I've seen many games not even work in NTSC, or have corrupted colors (Hudson Hawk through whdload is one)
@prowler
Yeah, it's the 1200/4000 (All the AGA Machines?) that have that feature. There is also a jumper on the A4000 motherboard (not sure about the A1200) that lets you choose PAL or NTSC as default. Switched mine to PAL for the above issues. If I ever get my second Amiga 4000D from Discreet... then I'll leave that switched to NTSC, because the Video Toaster I bought from them (haven't been able to use yet... :madashell:) requires NTSC.
Yeah, the whole NTSC vs PAL thing has been a pain for the Amiga. For the Atari ST, most games ran in NTSC, which for earlier games where programmers didn't take advantage of Amiga's custom chipset, the Atari ST versions appeared better (read faster) because of this.
Of course once about '89 (maybe '88?) or so rolled around the Amiga games definitely got better looking overall. Shadow of the Beast for the Atari ST for one was absolutely crap looking in comparison.

Yep, PAL has an extra 56 lines of pixels on the screen, at a loss of 10Hz from the refresh rate. So some games, if their timing is based on the VSync rather than arbitrary timing or CPU speed should run faster in NTSC. As pointed out though, this is at a cost of 56 lines from vertical resolution, probably where the OP's lives etc. were displayed.

Degrader (http://aminet.net/package/util/misc/Degrader) is a critical tool for any Amiga. No need for hardware mods with this thing! And it does much more than switch between NTSC and PAL. Absolutely essential for systems or games that don't support WHDLoad.

is there a way to tell whdload to switch to NTSC mode for ntsc games? I have been setting it in the boot menu but that is a pain.

Just add a tooltype to the icon that says NTSC and the whdload game will run in NTSC.

Cool worked like a charm.
Wow. Brian the Lion AGA looks outstanding on my new dell monitor. thats all it needed to fix the wide-space at the bottom. .
Thanks,

Does it only work for some games?

In Degrader, you simply click on 60hz System and hit NoReset. ALL NTSC games from here on out will be NTSC without fiddling with individual games' tooltypes...

Any game. And of course the PAL tooltype does the opposite.

where have you got that number from?
NTSC is 525 lines while PAL is 625
PS- ah, ok in LowRes 320 x 200 NTSC vs 320 x 256 PAL

PAL flicker sucks

Depends on the monitor.

Agreed, I have a LCD connected through the VGA out on my Indivision AGA, works wonders. The only 'flicker' I really notice is when on higher resolutions, (namely the interlaced ones) is a weird artifact of the mouse cursor and windows/icons when they're moved. But that's just in workbench, as opposed to in any games.
That's sweet about the tool types for PAL and NTSC. My question is, for games that are known not to work in one or the other, why aren't they in the stock setup for them?
