This is a new feature I'm working on. Every time you hit a boss it switches you to a different boss battle! Can you defeat them all?
Follow the steps for the usual build below. Then copy the .boss_rush_source folder into your _magicbox forlder.
If you have ROMs of Sonic 1, 2, 3, or Knuckles in your _magicbox folder they will be included in the boss rush.
On the startup menu go to BOSS RUSH (BETA) and switch it to "ON".
Then select any game as normal. You will be immediately put into Boss Rush mode in a randomly-selected game.
I've made a tracker specially for this. Unzip the BossRushTracker zip file and run the .exe file inside it.
Input the location of your _magicbox folder into the box at the bottom and it will automatically track your time in each boss.
When running the Magic Box, go to the BOSS RUSH menu. Make sure that EXPOSE DATA TO TRACKER is set to ON.
Follow the instructions for live splits above.
In the folder with the BossRushTracker.exe there is a folder called music. Put mp3 files in that folder.
When running the Magic Box, go to the BOSS RUSH menu. Make sure the following are set to ON:
START NEW BOSS RUSH
EXPOSE DATA TO TRACKER
USE EXTERNAL MUSIC
This has only been tested against one set of ROMs. It may not work with all versions of the games.
The tracker is a bit scruffy.
Sonic 1 - Rev 00
Sonic 2 - Rev 01
Sonic 3 - Rev 00
Sonic & Knuckles - Rev 00
Sonic 3D Blast (does not work with tracker yet)
A Mega Drive emulator that switches to a different Sonic game every time you collect a ring. Built by editing the open-source emulator GenesisPlusGX. My source code is available on GitHub.
Network play is supported from version 0.13 upwards. Twitch Chat interactions are supported from version 0.15 upwards. You will need to download the Magic Box VS Communicator to make this work.
Currently detects rings being collected in the following games:
Sonic the Hedgehog (GEN, MS, GG)
Sonic the Hedgehog 2 (GEN, MS, GG)
Sonic the Hedgehog 3 (GEN)
Sonic & Knuckles (GEN)
Sonic 3 & Knuckles (GEN)
Sonic 3D Blast (GEN)
Sonic Spinball (GEN)
Sonic Chaos (MS, GG)
Sonic Triple Trouble (GG)
Sonic Blast (MS, GG)
It also detects specific actions in the following games as if they were rings:
Dr Robotnik's Mean Bean Machine, Puyo Puyo and Puyo Puyo Tsu (GEN)
Streets of Rage 1, 2 and 3 (GEN)
Shadow Dancer, Revenge of Shinobi and Shinobi III (GEN)
Micro Machines 1, 2 and 96 (GEN)
Gunstar Heroes (GEN)
Ecco the Dolphin, Ecco the Tides of Time (GEN)
The Lucky Dime Caper (MS)
Mickey Mouse: Castle of Illusion (MS)
Wonder Boy III: The Dragon's Trap (MS)
Download RetroArch for Windows (32-bit version).
Please ensure you are running the 32-bit version of RetroArch, as the emulator will not run with the 64-bit version. I hope to fix this soon.
Run the installer for RetroArch.
Download Alistair's Magic Box for Windows (v0.26)
If you have problems with this version please try version 0.16
Unzip the downloaded ZIP file
Copy the file genesis_plus_gx_libretro.dll into the RetroArch downloads folder.
To find the location of this folder, open RetroArch and go to Load Core > Install or Restore a Core. The location of the folder will be at the top of the window.
Open RetroArch and go to Load Core > Install or Restore a Core.
Navigate to your downloads folder and select genesis_plus_gx_libretro.dll.
Navigate to your RetroArch folder. It should be one level up from the downloads folder.
Add a new folder called _magicbox
Copy and paste your Sonic game ROMs into this folder.
Works with all Genesis/Mega Drive games, but things to do with collecting rings only work in the following games:
Sonic the Hedgehog
Sonic the Hedgehog 2
Sonic the Hedgehog 3
Sonic & Knuckles
Sonic 3 & Knuckles
Other games can be swapped on a timer: e.g. every 5 seconds or every 30 seconds.
TESTERS: If you don't have any game ROMs download some from here
Open RetroArch and select Load Content. Load any ROM.
If installation has worked you should see a list of the ROMs in your _magicbox folder on the left-hand side of the screen.
If it has detected any ROMs in your _magicbox folder it will run the first one in the list, regardless of which ROM you selected.
Because this emulator juggles mutliple save states for different games, I've implemented functionality for save states beyond what's built into RetroArch by default
To begin all your games from their last saved state, switch BEGIN WITH SAVED STATE to ON
To choose how frequently all your save states are stored, use the AUTO-SAVE STATE menu item.
Hold down UP + START + B to access the in-game menu
Press UP or DOWN to choose an item. Press START to make it happen

Sonic 1, 2, 3 and Knuckles can now switch when Sonic lands on the ground.
Cooldown time can now be 2.5, 5 or 15 seconds
