Namco System 2: Marvel Land to Valkyrie No Densetsu Conversion?

[djsheep]

Can anyone help me out regarding what would be needed to do this conversion, or if it is at all possible?

I like Marvel Land, but not as much as I'd like to play either Valkyrie No Densetsu (or even Burning Force if it's a easier conversion?).

I also see there's an English patch for this game: https://coinoplegacy.com/en/valkyrie-no-densetsu-translation/ which interests me.

Or maybe I should just hope that Darksoft will do a multi one day....

It’s not a complicated conversion. You need the patched files, then you need to burn the rest of the eproms. As for the protection chip, you’ll need a diode. Last step is to configure the jumpers as you’ll use eproms instead of maskroms.

Thanks @futasan

https://www.arcade-projects.com/thr...em-2-any-game-in-rolling-thunder-2-jap.11620/ was my starting point. Shoot me a PM if you get lost. I also used those translated roms which make it way more playable for me, here are the files https://mega.nz/file/Vx5QjRKZ#g5qBS0ikxYUast9j7HXsRC7tW8SpWNipnolah9j4H2Q

Nice one. Gunna order the needed blank EPROMs for this. You got a list by chance? I know I could figure it out. I’m just being lazy…

Nope! But I did use a LOT of w27c020 to keep the weight down. Like 20 of them - probably doubled the image of it wasn’t the full 2mbit. That plus like a couple 28 pin like 27c256 or 512 might have done it. I think most were common.
