Atari Chat / Re: Atari 2600 with composite mod

Of course I have my PAL one - but NTSC games play with the wrong colours. I have a pile of PAL60 ROMs too which means I can play optimised PAL games but I'd like to be able to sample the entire NTSC library as intended.

Was just reading that thread over at Atariage!!!  :)

It does look good. It seems the cart used a weird bit of hardware for the extra ROM on the cart which made it harder to dump that usual.

Checking the 2600 again. The guy who did the mod has the audio and video leads together tightly. No doubt to keep the wires secure from harm. I suspect the audio is interfering with the video.  They are very fine wires.

I can't unwind them without disconnecting one of them. I do have a soldering iron but I've never used one. Would probably be a easy thing to do though - just disconnecting it from the terminal, unwinding and then resoldering it.

The interference changes when I twiddle with the wires so I'm pretty sure it's what is causing it.

Have had a US 2600 for a few years now.

I bought it originally in the mistaken belief I could use it with my CRT in the UK with an RF connection. My plan was to use it with my Harmony cart loaded with a full ROM set and then make a small collection of CIB copies of my favourites.

It's a 4 switch woody and when it arrived it wasn't in as nice a condition as described. It's OK - just not great. The switches were pretty seized up. The difficulty switches at the back were jammed - got one working and one snapped off. I can still adjust it with a screwdriver but it needs replaced. Its the P2 switch so will be rarely used - but still - I was pretty pissed off.

I complained on eBay and I got a refund to almost the full value.

So when I realised the UK TV tuners wouldn't pick it up I got it modded for composite. Bought a kit online and got a local electronics repair shop to do the mod.

Got that done and got a really nice clean picture - but - only in b&w.  The instructions with the kit stated there was a colour pot to adjust but it didn't seem to make any difference.

Bought a composite NTSC - PAL converter. Didn't work.

Tried it with several TVs , modern - even a projector - nothing. Still black and white.

So I put it away. The idea was to make it a project. Learn to solder - replace the diff switch and maybe recap it if that would sort the colour problem.

Lay for a 3-4 years.

Recently got a couple of "new" CRTs after my old one died. Thought maybe I'd try again.

Rigged it up - still b&w.

Opened it up and tweaked the colour pot again - and - colour!!!!!!!


But there is some interference on the image - diagonal stripes. Seems to be affected by sounds too. It's not a huge deal - is more noticable on certain games than others. Still would likeit sorted.

After some poking around on forums - it seems to be an interference thing - poor shielding on cables - and some power supplies can cause it.

The power supply is pretty old and the cables I'm using are cheap so I'm going to try that out.

I also have a 6 switch woody PAL unit with an RF connection that gives me a sweet image on my CRT. I have a pile of PAL60 ROMs of my favourite games on the Harmony so I always have that as a backup.

If I sort the interference out I may consider replacing the diff switch.

Just thought I'd post here and update from time to time.

May start posting more about some hidden gems I find in the huge NTSC ROM archive I have.  :)

When someone wants money up front to develop a prototype - that sends me a message that they do not believe in the project.  Someone who believes in it would invest some time and money to build a prototype. Then see if it can be productised - THEN look for funding.

The whole thing smelt bad to me. $300? pre-order with the info they gave? Thanks but no thanks.

You can add a POKEY chip to it to address that problem.  The issue is the POKEY chips are becoming rare and expensive!

read recently that there is a new POKEY compatible chip on sale. It has proven to work in Atari arcade games and 7800 carts as far as I remember. There are some issues with some Atari computers but it seems to be a workable alternative to finding an old chip.  Google POKEYOne for info.

I have ALWAYS dodged licence tie-in games. Even as a teenager I was suspicious of them. That has stood me in good stead.  :)

I'm afraid I don't have a lot of sympathy for anyone who coughed up money based on what evidence was available.

I hope it works out for people but I really don't see it at this point unless they pull a magic rabbit out of a hat.

Watched that. XMen v SF was either the 1st or 2nd game I imported. Can't remember now - it was a long time ago. I got Radiant Silvergun around the same time.

It's an amazing game on Saturn - would have been head melting to have played it when it was a new release.

I agree that the abuse the PS1 version got while justifiable up to a point wasn't really right. The game looked OK to me in the video and if you hadn't played the original or Saturn you probably would have enjoyed it.

I remember getting Meltdown in a pack of games but never got to play it as I had no gun.

Wasn't missing much going by that video though if the gun worked better it would help.....

I didn't bite at launch. I waited until I could vulture it in 2001 to my shame. But I got a lot of new games cheap for it then.

I have 2 DCs now with a good game collection and all the controllers (wheels, arcade sticks, guns etc). Great system. Wouldn't be without it.

I think so too. It's a slightly better deal for someone with an original Asteroids cabinet as they are getting Deluxe and Lunar Lander added. You get high score saving too which original Asteroids doesn't have.

For a deluxe owner it just isn't quite the same deal having original Asteroids added - but you are getting Lunar Lander too of course -  it's still something I'd consider in the future.

About £150 for the board. No soldering required for installation.

Added Ghouls & Ghosts to my MD collection. In really nice condition too.

I've read this is a bit more manageable than the ridiculously hard Super G&G on SNES. I play that on PS2 using the Capcom Collection which removes the slowdown that is evident on SNES.

However no G&G game is a walkover. I still play the original Ghosts & Goblins - usually on Wii's VC - but I remember playing it in the arcade too. G&G on MD is tough - have go to level 2 though which I haven't managed on Super G&G!!!!
