Patching Master System Games for Infinite Lives

[kyle]

I have a thing for infinite lives. I don't need to be invincible. I don't need infinite magic or ammo. I just want to be able to play through a game without having to replay a stage I've already completed. I have limited time for gaming between work and family. When I do have time I like to play games through to the ending.

This thread is for hard-coding infinite lives into Sega Master System roms. This is primarily useful when playing roms on real hardware via a flash cart. On an emulator an Action Replay code would suffice.

Feel free to request a game that isn't listed.

To patch a game:

Download LunarIPS (Windows), MultiPatch (Mac)
Download srktt.com/files/smscheat.zip
Patch a matching .sms rom with the .ips file

Tutorial to play along at home:

Open a recent build of Meka with the cheat finder
Load a game and get into the actual gameplay
Press the == button on the cheat finder without any additional input
Lose a life
Hit the < key
Lose another life
Hit the < key again
Repeat until you run out of lives
You should end up with a few ram values where the life counter is stored
Click on one. If it flickers or shows a constantly changing value move on
The good value should be one that decreases each time you die
Scribble this down once you have it. It is half the puzzle

Reset the game or hit continue and get back into gameplay
Open the debugger
Type the c key + enter to continue
Type b + space + w + space + the ram code above and hit enter. This will freeze the game when it is read or written to
Focus on the game play window and kill your character
You should see a rom value when it is decreased. Scribble this down as well

Open the memory editor and click on rom
Type the value from the debugger and hit enter. It will jump to its position
Try changing its hex value to a 00 for a noop. This will tell the game to do nothing in place of the decrease
Other potential values are:

12 - 1A
22 - 2A
32 - 3A
35 - 00, B6
70 - 46
77 - 7E

Saw this over at SMS Power, I applaud the effort put in and like the concept, even though I would probably have little use of it personally (not to be confused for bragging as I suck at most challenging games).


That being said, there's no PAR function on the SMS emulator on the DS.

[kyle]

Yeah it's mainly useful with flash carts and real hardware. I prefer them to emulators.

[lambrettadave]

If I knew how to get more games on to my Tototek it this would be usefull

[grolt]

Great idea and initiative - I have the same gameplay philosophy as you. I've toughed it out and completed the hardest of SMS games on real hardware without cheats (Cloud Master, those later Shinobi games), but these days it is so tough to find the extra time to game that I don't want to waste it re-doing stages. Not being invincible is important, since that's the thrill, but knowing you're not going to have to start a full game over is a nice thing. I also like having level select hacks as well, so if you do have to leave a game before completion you can just jump right in the next time you fire it up.

[ronstard]

Can you put patches for Space Gun and Laser Ghost? Thanks for your efforts!

[kyle]

Sure. They're up. Sorry for the delay. I don't check this forum often. Feel free to post in this Krikzz thread if you don't get a timely reply from me.
