Section Structure

Offset	Length	Description
0x0000	2 bytes	Offset to ability name
0x0002	2 bytes	Offset to ability description
0x0004	1 byte	AP Required to learn ability
0x0005	1 byte	Refine table (m00X file index) — which Refine data table this ability’s item list is drawn from. Menu_Prog19_RefineMenu_Init switches on this byte to load a pair of mngrp resource files: 0=Magic Refine, 1=Tool/Medicine Refine, 2=Mid/High Magic Refine, 3=LV Up Refine, 4=Card Mod. 4 also builds its on-screen list from the cards you currently own, but it still loads and slices a real recipe table (section 192) like the others. 255/128/129 (Haggle, Sell-High, Familiar, Call Shop, Junk Shop) aren’t Refine abilities at all and ignore Start/End offset
0x0006	1 byte	Start offset — start of this ability’s inclusive slice of its Refine table’s records. Menu_Prog19_RefineMenu_Init computes count = End offset - Start offset + 1 and offsets the table pointer by 8 * Start offset (each record is 8 bytes)
0x0007	1 byte	End offset — end of this ability’s inclusive slice (must be ≥ Start offset). Abilities sharing the same Refine table use non-overlapping slices, e.g. T Mag-RF (table 0, 0-6) and I Mag-RF (table 0, 7-13) split the same loaded item list by element

Refine table record format (menu.fs, not kernel.bin)

The item/magic conversions themselves are not in kernel.bin — they live in menu.fs’s mngrp.bin, in the mngrp section pair each table loads: 188/196 for table 0, 189/197 for table 1, 190/198 for table 2, 191/199 for table 3, 192/200 for table 4 (Card Mod) (Menu_Prog19_RefineMenu_Init). Card Mod’s on-screen list is built at runtime from the cards you own, but the card→item recipes it slices with Start/End offset are still this static section 192. Decoded via sub_4D9600/sub_4D9660 (the Refine screen’s row-name resolvers), each record is 8 bytes:

Offset	Length	Field
0x00	2 bytes	Display text offset (not needed to decode the conversion — names are resolved from the item/magic/card lists directly)
0x02	2 bytes	Output quantity
0x04	1 byte	Source quantity required
0x05	1 byte	Source material id — item id for tables 0/1/3, magic id for table 2, card id for table 4
0x06	1 byte	Unconfirmed (constant 1 in every sample checked)
0x07	1 byte	Destination material id — magic id for tables 0/2, item id for tables 1/3/4

Verified against the retail menu.fs and matches the well-known FF8 Refine chart, e.g. T Mag-RF: 1x Coral Fragment → 20x Thundara, 1x Dynamo Stone → 20x Thundaga, …; Mid Mag-RF: 1x Fire → 1x Fira, …; Card Mod: 1x Geezard → 5x Screw, 1x Fungar → 1x M-Stone Piece, 1x Blobra → 1x Rune Armlet, …

SolomonRing’s Menu Abilities tab can load mngrphd.bin/mngrp.bin and show the decoded table for the selected ability directly (reference only — this data isn’t part of kernel.bin, so there’s nothing to save back).
