My Mario is Broke

[Blue Azure]

Bob says I like to make games that I can't die. That's normally true. This game you must die so you can see where you're going. Sadly, playing this version will improve your Mario game. Try it and you'll see.

 

MARIO BROS player 1 start number of lives is at address $B903. In after-hours hacking, I found $B907 is player 2 lives, but this change is not included in this game.

 

Replace $A9$03 with $A9$61 for 98 lives.

Replace $A9$03 with $A9$FF for 256 lives.

 

As homework, try loading $A9$0E @ $B903 as maximum lives displayed without totally obliterating your screen. For the purposes of demonstration, I show 98 and 256 here…

 

NTSC MARIO BROS, emulator, 98 lives (actually, I think it's 97 but who's counting?)

MarioBros98.a78

 

NTSC MARIO BROS, emulator, 256 lives for those who have the patience

MarioBros256.a78

 

Some of the most important discoveries occur at 2am. This probably wasn't one of them.

I don't mean this offensively at all.. but have you considered a more... meaningful hack to make a game a bit more original? Similar to turning PacMan into Ms PacMan back in the day?

It would be much cleaner to just find and disable the decrement when a life is lost.

Like adding Pokey audio to it lifted from the A8 version, perhaps?

Blue is the 7800 game genie aka cheats enabled. Check out space junk to see a graphical type of hack that he has done.

Not to worry guys, this is a video game blog and everyone is entitled to their own opinion. You can't ruffle my feathers as I have very few remaining...

 

I surround myself with kids that love "junk" bins. They always say, "Show me the damage," and so I do. I showed them this and they laughed. Perhaps one person's trash is another person's treasure - rarely though. This "game" is damaged and admittedly has no where to go. I've accumulated tons of code and plan to do something with it some day...eventually. I doubt I'll exactly follow Bob's footsteps, however. Who could? My complete 7800 collection spans over 5GB in full documentation including Bins and A78s, board schematics, chip specs, source lists, disassemblies, hardware and software whacks and hacks, sprite development, artwork, and photos and videos, and obscure analyses you can't imagine. There's very little missing. So there's little doubt where my head's been at in recent time. Sadly, it's no wonder my dog forgot my name. He doesn't see me much when I'm working all the time. But we will have a whale of a Christmas.

 

I did investigate the Mario lives decrement, after the fact. 404 City. Perhaps an increment is used to do the "decrement" so we'd have to chase increment codes E6,F6,EE,FE, or there are other ways to manipulate the data.

I searched for Player 1 decrement of lives…
C6 A1…nothing found
D6 A1…nothing found
CE 14 18…nothing found
DE 14 18…nothing found

I searched for Player 2 decrement of lives…
C6 B2…nothing found
D6 B2…nothing found
CE 15 18…nothing found
DE 15 18…nothing found

So some other method must have been employed, or my computer is lying to me. Sorry, no bingo!

Look for code that modifies the addresses you found to contain the number of players...
