i just bought a nes action replay from ebay.
the problem is it is a pal device.
i have a rgb modded nes that i only get a gray screen.
i have done the region mod also on the rgb nes.
on a normal composite video nes i get a picture but is is very unstable.
i have not done the region mod on this nes. it has been untouched.
is there a way to convert a pal nes cart to make it display ntsc video?
i originally thought the nes would run the game as needed for the region the nes was ment for.
so if i played a pal game on a usa system other than a region check it should work and out put ntsc video.
or if i took a ntsc nes cart and played it in a pal nes it would display in the pal format.
is there something i can try and change to get a more stable picture in the action replay cart?
Nope, the only way to get a 50hz NES program to play correctly on a 60hz console is to rewrite the program. (Pasted from my response on Cherryroms ;)
nes action replay hints
it will work on a ntsc nes but you cant see everything real good.
on my modded rgb nes i just get a gray screen but i have entered codes
with the below steps
blind usage guide.
the action replay starts at the 1st code entry location on the left side.
up and down selects one of five code entry loctions
B(up 1 value 0-F) A(down 1 value 0-F) LEFT or RIGHT selects new variable location.
hit start to start the game with entered codes.
000Y:YYxx(Y=ADDRESS X=VALUE)
SELECT VALUES WITH NES A AND B BUTTONS.
A_____B
16=0=0
15=1=1
14=2=2
13=3=3
12=4=4
11=5=5
10=6=6
9=7=7
8=8=8
7=9=9
6=A=10
5=B=11
4=C=12
3=D=13
2=E=14
1=F=15
holding down any one button or direction on the nes pad will auto repeat.
like rapid fire. so hit the needed button fast. if you dont it will register multiple
hits.
there is one switch on the nes action replay i have it in the up position(the female
socket side).
so far any codes found in emulators will work just find with the real action replay.
you just have to modify the 1st parts as needed.

Quotei have a rgb modded nes
how do you do that?
or,
where do you get that?

what about over/under clocking the whole system?
The NES video encoder doesn't natively output RGB. The time-honored way to apply such a mod is to swap in a pin-compatible encoder, usually from a Famicom clone or NES-on-a-chip device. If you're not used to soldering surface-mount components, it can be a pretty involved and challenging process.
Clock speed of the NES or Famicom unit does not affect its video output. Unlike other consoles, the refresh rate of the video signal is strictly a function of the software. The Sega Master System generates a raw RGB signal that is made PAL or NTSC based on the video encoder settings, which is why most games of any region will generally run on any console. The NES and Famicom games must have a patch, or be dumped and recompiled. There's no easy to to do that with a hardware mod. and you can't enter a code into the Game Genie to change its video mode... At least, not without plugging a second Game Genie in front of it to patch it. :)
All this stuff is covered in the various spec sheets relevant to 8-bit consoles. You should have a look if you're seriously interested in this sort of modding. Keep in mind that software patches are gnerally considered outside the scope of conversation here at GamesX.

2 game genies? <_< for real?
Well, yeah. You can't use the Game Genie to change the code on itself, so you need a second one to modify the code on the first. Obviously, that's a silly solution, since the second Game Genie would have to be video-compatible with the console and would therefore be redundant.

i do have a ntsc game genie and a pal action replay.
did you think the problem i had was with a pal game genie?
maybe i could use a ntsc game genie with a code to change the action replay to ntsc?
sounds crazy but its would be worth a try..

If you want 50hz theoretical NTSC output, sure. I don't think thats even a possibility though since the PPU derives the video from the master clock and it probably requires that clock for any sort of video generation. PAL NES have entirely different PPU which work on a different clock frequency (and get colors differently than the normal NTSC based PPU)
Sure you can change the AR to NTSC, that is if all you need to change is under 5 bytes (or however many the thing can patch) which is probably not the case unless there is a 50/60hz pointer ;)

most likely not easy to find?
a dump of the action replay would be needed and mad skills.
2 things i dont have :P
oh well at least i have my blind usage guide.
Is there a NTSC AR? You could always swap the ROM you know
