Mario Party N64 Combo Mod

Combine Mario Party 3, 2, (and optionally 1) into a single ROM for console or emulator.
Most flashcarts for console have a 64MB ROM limit so the patcher outputs 2 files: mp3-mp2 combined and mp3-mp2-mp1 combined

FAQ

When I start the game, it says I need to set the save type to 16KBit?

This means your emulator did not set the save type correctly.
Project64:

1. Run the game.
2. Go to Options > Configuration > Config: MarioPartyN64Combo.
3. Set Default save type to 16-kbit EEPROM.

The game crashes when loading minigames from other Mario Parties

Some emulators lack perfect N64 accuracy.
Project64:

1. Use Project64 4.0 (development build).
2. Go to Options > Configuration > Config: MarioPartyN64Combo > Recompiler.
3. Set CPU core style to Interpreter.

If issues persist, try the Ares Emulator.

The game froze when the minigame wheel should have appeared

You may not have selected enough minigames for that category.

• Restart the ROM.
• Press Z to open Minigame Settings.
• Add more minigames to the desired category.

Will Daisy and Waluigi ever be playable?

Probably not until decompilations progress further.
