@never-obsolete: Please. :)

I've emailed retrousb to check this out. I don't have any high hopes for an answer but anyway.. :)
I suspect these "problems" would also appear with mapper 2 & 3.

Sort-of yeah, mapper 0 implies no mapper. So how is the WRAM mapped in? :) I guess that's why some emus don't like it, it's decided to be an impossible cartridge. But in practice of course, blocking this only creates headaches for developers.

Highscore save hacks would be kinda cool, I had thought about trying to put that into a server program that the NES would communicate with over the controller port.

I am less than a newbie concerning the hardware, but I just thought the WRAM was connected straight to the NES hardware itself through the cartridge-oonnector, with no MMC's required, but obviously I was wrong then. :)

74LS20. It's quite a basic decoding circuit.

That or they don't implement the keyboard and therefore can't run the only mapper 0 game that uses PRG RAM.

Sorta forgot to post these:

Galaga[sram].zip
Tetris[sram].zip

I've only played one player with the Galaga patch, so player two may not work. Also, here's one for Contra that lets you carry two weapons like Contra 3:

Contra[dualweapon].zip

The select button toggles back and forth.

Any chance these patches still exist? I'm dying for a Galaga that saves the score!

I've done a few highscore-saving hacks aswell, it's on my website. I'd love to add in-game highscore list (with editing) but.. too much work. :/

oRBIT2002, love your patches! :)
Would you be interested in doing a patch to allow VS. Wrecking Crew to work on a 1-player VS, so it can work in most emulators that only emulate 1 side VS. board for use in fceux, mesen, or even a regular vs pcb on 1 side? But still maintain the VS platform? :)
I figure you have already figured out how to put the game into 1 player mode with your VS. to NES conversion, so it might be possible to just use that part of the patch on the VS rom? I could be wrong though :wink:

I edited my original post with the patches. The Tetris one should probably be converted to an xdelta patch.
. That's just like, your opinion, man .
