Now, the thing is confirmed to work 100% fine on real hardware !! Ha-yaaa !
And my page have more precision on rewiring for beginers.

I just cut track to pin 23 instead of 22 and that was why I was getting so much problems before.

I am afraid that unfortunately is a problem in multiplayer mode, game hangs after the completion of energy zone (after introducing the animation). Tested on real hardware (Famicom and NES)

I uploaded both the patches I have here:

Unfortunately, the MMC3 conversion was made against the version of the translation that used that silly Gryzor title instead of Contra. This prompted me to add VRC2 support to QuickNES.

kode54, could you please remove this link ?
This guy is likelygoing to sell bootleged carts based on my hack, which of course I don't want him to.

That being said, this hack was a stupidity I did back in 2005, long before the PowerPak was released. It has absolutely no value other than for bootlegs.

Today anyone can play the original Gryzor/Contra or whathever hacked/translation of it on their PowerPak.

Well, let him. Someone said that there's a bug, so eventually his customers are going to notice and start complaining about it, and hopefully learn the downside of buying such products.

i don't know why you are saying i'm trying to build bootlegs to sell them

i never wanted to do something like this and i don't understand why you claim i would do something like this

i like contra have played through it a hundred times and then i found this version with some neat video sequences in it and wanted to play this version on real hardware.

just some stupid celler kids who do such things and think i could harm their business

Well, I didn't think of that. Removed, but he probably already got it.

Sure this is possible using a PowerPak from RetroZone. (which didn't exist back when I made the patch).

Epilogue: They tracked that down. See topic 8274, topic 8569, and the wiki. It looks like a half-done interface for a Microwire EEPROM chip.
