Awesome work! Your patch appears to work with the US console FM-sound patch, and the D.C. hack, although I haven't tested them extensively.
edit: More roms it can be combined with: Turma da Monica em O Resgate (B) Turma da Monica - The Escape Sonic-Boy 2 - Eggman's Trap Guerreiro Lobo V2.0 Update: These all work with v1.2 as well :) |

Do you have to go to the password screen for it to save? Either way, awesome work. | |

You must enter in a "password house"
(the password is generated in them) |

I love this! I used to think the new Wonder Boy 3 remake made the original obsolete due to the save system, but just like that, you've turned the tables!
Thanks a lot. |

I just tested this on a Mega EverDrive with a modded Nomad for SMS compatibility and it worked great! Thanks so much! | |

Little update
- Fix a tiny bug (emulators) - Autodetect pad type, with a MD/GEN pad, Start act as "Pause" button (object menu) - Stack/slots init corrected to work properly on MD. If you make a repro, and have a simple/cheap MS to MD adapter the game will work. - if no save is present, continue launch a "new game" File in 1st post |

At first, thanks for this very useful patch. I'm having a great time playing Wonder Boy Dragon's Trap without taking note of those long passwords.
However, when the IPS is applied to "Turma da Mônica em - O Resgate" rom, it kinda works, but the game displays some collateral effects like: black screen/freezing when entering the password menu or any password room; messed up text in the first menu (as shown in image). Comparing the Mônica rom with the Wonder Boy one, the culprit is probably the space between 7F07 and 7F56, which has additional data in the former rom, and is replaced by the patch, while the later has 0's in the same addresses. The section seems to hold some portuguese translation like "OURO" (GOLD). Any help solving these would be very appreciated. |

Coin multiplication bug

As some may perceive, I've been a bit addicted to these Wonderboy games lately.
Sorry for double posting, but I think this is worthy mentioning in a new post. I may have found two bugs in this SRAM hack. The first one is a coin amount bug after resetting and continuing. For example, when I saved the game, I had 46 coins. When I reset the game and CONTINUE, I'll have 80 coins. The same happens whenever you get more coins and save the game. In other occasion I had 155 coins, after saving and resetting it raised to 240! The second bug happens when I use a Genesis 6 button controller with the SMS (Alex Kidd BIOS). Some button pressings, or combinations cause the game to randomly pause. The most frustrating is when I press jump for the Hawk-Man to fly. The game starts pausing constantly when pressing the same single button two or three times quickly. Do these bugs occur to someone else? |

The password system doesn’t store gold with full precision, so if the SRAM patch just stores the password to SRAM then it will have the same limitation. | |

I was facing the same problem. |

It was years ago, from memory i've only tested with official md pad 3 buttons. | |

Thanks, this explains a lot. I should have tried the password before calling this a bug. I never noticed this behavior before, probably, because inserting the password makes me forget my coin count, while restarting the game and immediately sram reloading makes this more evident. Regarding the 6 button controller, I circumvented the issue by: a) patching a clean rom with the first sram patch file (1.0 maybe), found in the first post of this thread (wb3_save_edition.ips.zip) b) then patching the same rom with this Start Button + FM + border color fix patch here: https://www.smspower.org/forums/post123041#123041 Regarding Turma da Monica rom, I couldn't succeed, but I'm checking what can be done. |
