What happens if I play X on Y, or Y on X?
Can it cause problems?

I bought Tron 2.0 on eBay from USA and I'm in Sweden.
I can play the game just fine (with Killer App Mod of course) but when I shut down the game I always get an error message.

I asked one of the devs behind KAM but it probably wasn't KAM's fault. More like on my end.

PC version?
PC doesn't use PAL or NTSC, those are (old) television signal standards.

If you bought a console version NTSC and want to play in on PAL equipement it probably won't work.

Also, even if he did play an NTSC version on PAL equipment (= an old CRT TV), that would only affect image quality on the screen and not cause any kind of software errors...

Silly me. I thought PAL and NTSC were for PC's too.

Not sure about how that would work with old console games. Older consoles did have PAL/NTSC specific hardware, and the games were made in separate versions for the two. I don't know if the NTSC version of a game would even run on a PAL console, even without taking possible region locking into account.

But of course, if the OP is talking about the PC version, the point is moot anyway. Nope, those are TV picture standards, so they're only applicable to older consoles.

Edit:
And old computers of course. The C64 also came in separate PAL and NTSC versions, for instance.

Since I last talked to you about this, I think I've figured out what causes Tron 2.0 to crash on exit. (The crash doesn't do any harm, but it is annoying. It still happens without the Killer App Mod, on plain vanilla Tron 2.0, as well.)


This solution worked for me.

Go into the Windows Control Panel > Click System > Click Advanced System Settings on the left side of the window > Click the Advanced tab on the window that pops up > Click the Settings button under Performance > Click the Data Execution Prevention tab > Click the radio button labelled "Turn on DEP for all programs and services except those I select".

Click the Add button near the bottom > Browse to "C:\Program Files (x86)\Buena Vista Interactive\Tron 2.0" (this is the default install location for the CD/DVD version of Tron 2.0, the Steam version installs elsewhere) > Select Lithtech.exe and click Open > Make sure you see an entry labelled "Client MFC Application", with a checkmark in a box beside it > Click OK > Restart the computer.


After implementing this change, Tron 2.0 no longer crashes for me on exit. (Before, there was about a 50/50 chance of it crashing for me on exit.)

Turning off Data Execution Prevention (DEP) for Tron 2.0, might also prevent other crashes. But, to be honest - except for the crash on exit - I've never had any issues with Tron 2.0 while DEP was turned on.

For Killer App Mod v1.2, I'm going to have it add Tron 2.0 to the DEP exception list automatically.

I'll try your tip, Rain. I hope you don't think I blame you and your mod, that was not the case.
I just thought NTSC and PAL was on PC's too and that was causing errors to my copy.

ntsc software will work on PAL tv's
trust me on this ;p

it depends mostly on the tv but even back in the late 90's and early 2000's if you had a high quality ( ie expensive ) tv or a 100 hrtz tv you could play ntsc on a pal tv

and today the whole thing is moot

i have an american ps2 american 32X ( with american megadrive no i am not calling it a genesis ! ...wait )
and an american saturn hooked up to my flatscreen
everything is in color nor is there any slow down
and even before that bargain basement crt's could display ntsc

course light guns wotn work on lcd's
and to actually play ntsc games on a region locked console you usually need an adapter ( or just import the console with a step down converter )

60Hz signals, definitely, NTSC is less guaranteed. I have a US copy of Hey You, Pikachu! for my European N64 (along with a device to circumvent the region lock); that displayed fine in color on an old, cheap, no-name 14" CRT TV I had many years ago, but it's in black and white on my current 40" LCD Sony TV.

that is probably because of the cables you are using
some tv's dont really react well to old av cables
though my lg tv does just fine with my snes hooked up to rf

looks not half bad either

IIRC, my GameCube uses the *exact* same kind of cable; composite through a SCART adapter. There's no problem with either 60Hz or imports for that one, and it's all going into the same SCART port on the TV, too, thanks to a SCART switch.

Of course, all of it is currently locked away in a storage facility a couple of hours away from here, so I can't double-check.

No worries. :) I'd just like to know if my solution works for you.

Yup, it's not applicable for PCs. But there were devices that you could plug onto your consoles to allow them to run games that were imported. You could also have imported the console+tv from the region of your choice and used a transformer to plug them in. Whichever was the most convenient.

Well in some cases (older than the PSX) the difference was that PAL consoles had clock speeds 1/6th slower than their NTSC counterparts. The software was basically the same between versions and the lower frame rate was achieved by the game running slower on the slower CPU. Fun times to be a European!

You misunderstood what I said completely. I didn't say anything about using an NTSC signal for a PAL TV, I talked about using an NSTC game on a PAL console, which is a completely different ball game. But can you play PAL games on those American consoles? That is the question. Not whether or not the consoles will work with PAL TVs.
No, that's not exactly how it is. It's not the CPU that's slower, it's the screen refresh rate. As such, it only affects routines that are linked to the screen refresh rate. In actual fact that means that a PAL C64 has more clock cycles per frame than an NTSC one, which again means that PAL routines can't always run reliably on an NTSC C64. Here's an in-depth explanation of the differences between the PAL and NTSC versions of the C64.
