So, I talked with the thrilla, Souzilla, yesterday. He has made other HSS kits, for other games using the Z80 chip to rewrite code. I asked him if he was going to tackle the Vs Nintendo games, even though they use the 2A03 chip and no Z80 (like DK, DKJR, Punch-Out, etc). He and I were wondering what were the problems others have run into with this project before?

So my discussion to the group is: I remember some folks have tackled this in the past but why didnt it work? I do understand that each Vs game is unique to each other and it would be horrendous/tedious to sort out code for each game. I believe it has both Phet and Frizz that I discussed this with.

My idea was this: I would be willing to offer my Vs Balloon Fight board up for the project. I feel that this is the one game, for certain, that alot of folks own and would love a HSS kit for. I'm also aware that this may be little to late, as there seems to be a massive Red Tent exodus, as of late. But I thought I'd throw this out there. Thanks. Discuss.
 
There's no problem with it... I've got a handful of vs games that save scores... desoldered the 6116, replaced it with a NVRAM and modded the ROMs.

If there's not a C compiler for the playform Souzilla isn't going to be able to help you... it needs to be done in assembly.

With Mark on hiatus, is there anyone else that has attempted this before?
 
If there is no pascal compiler for the platform, mark is not going to be able to help you
 
ok, I have some time so I will take a look at this. Are people interested in free play with attract or just high score saving?
 
so a couple of things...

1. The high score save mod for Balloon Fight is already done, it was not too difficult
2. This game is not very fun, am I missing something?
3. I will work on the free play with attract mod soon, please stand by
 
So.. did only one of the rom files change?? .. You didn't have to desolder anything?

Veryy awesome...

Sort of OT, Maybe you can figure out the PPU color information too :)
 
Right now it is two roms changed. You would likely need to replace the 6116 ram with nvram. Not sure if they are soldered in.

As far as the PPU, let's not get crazy :)
I don't own any Nintendo VS games, I am only doing this because people have asked and I have some time to look into it.

Balloon Fight is cool. Thanks. Need me to beta test? :D I have some NVRAM.

I think Super Mario Bros. is a must. Then after that, the rest are all personal favorites of everyone and that's gonna vary.
 
Can you check to see if the 6116 ram is socketed or not?
