How to Build Your MUGEN / IKEMEN Collection!
M.U.G.E.N & IKEMEN Roster Architecture Guide
Mastering select.def Configurations, Slot Organization, and Custom Collections
The roster configuration defines the structural playground of your fighting game build. By mastering your system's data files, you can cleanly organize character rosters, group fighters by universe or category, map hidden boss characters, and assign customized stages to specific combatants. This guide covers fundamental registration logic, workspace setup, and how to successfully manage mass roster updates.
1. Mikazuki's Recommended Video Learning Library
To understand exactly how coordinates, text syntax, and directory paths interact inside the engine, follow these sequential walkthroughs to build, scale, and debug your selection grids:
Roster Foundations
A step-by-step primer on locating engine data structures, creating directories, and declaring files correctly.
Slot & Grid Layouts
Advanced techniques for assigning custom grid slots, positioning elements, and handling spacing variables.
Troubleshooting Errors
Isolating syntax errors, identifying broken path hooks, and tracking down files that cause system crashes.
2. Core Directory Infrastructure
Every single roster choice on your selection grid is powered by a central map file located inside your game environment:
; Format: character_folder_name/character_file.def, stages/custom_stage.def
Kyo_Kusanagi, stages/Esaka_Stage.def
3. Customizing Pre-built Game Collections
Many creators choose to download massive, pre-configured community builds (like Jump Force MUGEN or compilation engines) to use as a foundations. If you want to modify, add, or remove characters from an existing build, pay close attention to this structural workflow:
- Audit the Original Select Map: Before deleting or replacing files, open the game's native
select.deffile. Analyze how the original author structured their character tiers, hidden boss configurations, and spacing parameters. - Clean Asset Removal: To completely wipe a fighter, remove their directory lines from the selection script, and safely delete or archive their character package out of the engine's
chars/directory to free up build storage. - Adding Custom Tiers: When introducing new characters to the bundle, inject their folder configurations cleanly into empty grid slots or replace existing placeholder profiles while maintaining the underlying resolution metrics.
4. Detailed Text-Based Guides
If you need an explicit, step-by-step structural checklist to follow alongside visual guides, consult this community documentation:
Experiencing "Can't Open File" Errors or Selection Screen Crashes?
If the engine throws a black screen, skips character portrait assets, or fails to launch entirely after registering a file—drop your select.def string below and our technical support staff will trace the error!
