Kof Theory Mercenary Screenpack 400 Slots Down... //free\\ May 2026

It sounds like you're looking for a solid, step-by-step guide to configure the KOF Theory Mercenary Screenpack for M.U.G.E.N (likely 1.0 or 1.1) with 400 character slots.

Quick fill (Windows PowerShell):

p1.pos = 10,20
p1.gridsize = 10, 10   ; 10 across, 10 down = 100 per page
p1.pages = 4           ; 4 pages = 400 total

1. Prerequisites & Understanding the Slot System

• M.U.G.E.N 1.0 or 1.1 (most KOF screenpacks work best on 1.0)
• The screenpack folder (e.g., kof_theory_merc/)
• The select.def file controls slots, ports, and order.

10. Final Checklist

• [ ] select.def has exactly 400 non-comment lines in [Fight]
• [ ] system.def → p1.gridsize product = slots per page × pages = 400
• [ ] Page left/right keys work
• [ ] No crashes when scrolling past last slot
• [ ] Portraits display correctly
