ApolloBoy Posted November 4, 2003 Share Posted November 4, 2003 After losing an auction for Planet Smashers and Midnight Mutants, you can imagine how disappointed I was, so now I want to get the easier-to-find PAL versions (those Europeans have it easy!) and convert them to NTSC format so I can play them on my NTSC 7800. What do I need to do, and where can I get the proper materials? Quote Link to comment Share on other sites More sharing options...
+Mitch Posted November 4, 2003 Share Posted November 4, 2003 If you are buying the PAL version of the game then usually all you need in addition is to buy an EPROM of the correct size and type. A few PAL games are larger than the NTSC version, these can be made to work with a little work. If you do end up making some of these please mark them, at least internally, as repros. I can just see people a few years from now thinking that they're either protos or real NTSC carts. Mitch Quote Link to comment Share on other sites More sharing options...

+Mitch Posted November 4, 2003 Share Posted November 4, 2003 27C100 EPROM, though the more common 27C010 will work with a bit more work. You will also need a second EPROM for Alien Brigade, a 27C128. Mitch Quote Link to comment Share on other sites More sharing options...

Mitch Why? Because Alien Brigade is 144k in size and they don't make 144k EPROMS. So, they use a 128k and a 16k. Mitch Quote Link to comment Share on other sites More sharing options...

Ian Primus Posted November 4, 2003 Share Posted November 4, 2003 But, aren't we missing something here? Just copying the cart onto an EPROM cart won't magically convert it to NTSC. There is also a lot of code modification that needs to be done... Ian Primus ian_primus@yahoo.com Quote Link to comment Share on other sites More sharing options...

Ian Primus ian_primus@yahoo.com Eh, there aren't any. Sentinel would be the only one and a completed NTSC proto exists for that one.

I guess since the 7800 wasn't as widespread and didn't last as long as the 2600, and therefore there weren't nearly as many games, they managed to get ganes released in both formats. The fact that nearly all of them were made by Atari helps too. You learn something new every day... *slinks back to the 2600 forum* Ian Primus ian_primus@yahoo.com Quote Link to comment Share on other sites More sharing options...
+Mitch Posted November 5, 2003 Share Posted November 5, 2003 There are several 7800 games that are NTSC only, no PAL version available. So you were partly correct, just in reverse. Mitch Quote Link to comment Share on other sites More sharing options...

Do you have the seperated ROM file I need? I don't know how to use a hex editor and I don't want to know how at the moment. Quote Link to comment Share on other sites More sharing options...

Unfortunately for you and other PAL users, there is no PAL 7800 Robotron. Mitch Quote Link to comment Share on other sites More sharing options...
Tizoc Posted November 21, 2003 Share Posted November 21, 2003 Just a note, if you are not interested in the labels and are more interested in playing the games on your console, you don't have to buy their PAL counterparts. There are other more common games you can use to just get the board then solder on the EPROMs. Most of those games on your list use the same board anyway. O'sheas might still have some of the games with the board you need. BTW, if you plan on burning the EPROMs yourself you will have to deal with HEX. HEX is your friend. :-) Good luck!
