Other 3

Changes that fit none of the other sections.

#35 The title screen now says FINAL FANTASY VI, and the ROM's internal name says 6.

In 1.0: The title screen logo read FINAL FANTASY III, the game's US number, and the name stored inside the game said FINAL FANTASY 3.
Now: The logo now reads VI and the stored name says FINAL FANTASY 6, as in the Japanese game.

Title logo: TitleOpeningGfx (D8/F000), the LZSS-compressed title and opening graphics. In the decompressed block the logo is a 256 by 64 pixel band, tile layout at offset $8BE0 and tiles at $8DE0, drawn over the flames with the letters cut out. The three III bars are cleared, a V is drawn anew from two 5-pixel diagonal bars with the same flared tops, one original I bar is kept, and the band is re-tiled into 130 tiles, within the 136 the title code copies. Recompress; if it outgrows the block's 36 spare bytes, move it to free space and repoint. Internal name: in SnesHeader (C0/FFC0) change the digit at C0/FFCE from 3 to 6 and update the header checksum.

#237 The ROM is now 4 MB, making room for the new enemies, maps, scripts and graphics.

In 1.0: The original cartridge is 3 MB, with about 26 KB of free space in small gaps, far too little for new enemies, maps and event scripts.
Now: The ROM is now 4 MB, with room for the new enemies, maps, scripts and graphics.

For ROM hackers Method

Pad the 3 MB ROM to 4 MB: file offsets $300000 to $3FFFFF appear as banks F0 to FF in HiROM. The header's size byte at C0/FFD7 already declares 4 MB ($0C), so it stays. Blocks that outgrow their banks move there and are repointed: monster graphics (MonsterGfx, E9/7000; a 256 KB block in this ROM hack), monster palettes and stencils, the AI scripts (AIScript, CF/8700), the per-monster and formation tables, and later the map records, the treasure table and the dialogue pointers. Code that supplies a bank as an immediate must change with the move, such as the Colosseum wager screen's lda #$E9 at C3/AF8D and lda #$D2 at C3/AFFD. NPC records hold 18 bits of an event pointer, so NPC events placed there are reached through call and return stubs in banks CA to CF.

#509 The Equip screen and the ending no longer break on a 50 Hz (PAL) console; 60 Hz play is unaffected.

In 1.0: On a 50 Hz (PAL) console, the Equip screen drew only its top bar, and the ending stopped for good at its sixth music cue.
Now: The Equip screen now draws in full and the ending plays through; 60 Hz play is unchanged.

Both fixes run only when $213F bit 4 reports 50 Hz. Equip screen: the main menu drives $212C from HDMA channel 6, which the Equip screen reprograms, and at 50 Hz a stray value is left in $212C. Replace each lda #imm / sta $212C at D4/CA61 ($17), D4/CDE3 ($1F), D4/CEC2 ($17) and D4/CF08 ($13) with a jsl to a routine that writes it and keeps a copy in $024E. In MenuNMI (C3/1387) replace the jsr UpdateMode7Regs at C3/1454 with a jsr to a bank C3 routine that, at 50 Hz with $024E nonzero, writes $024E to $212C, then jumps to UpdateMode7Regs (C3/D263). Ending: insert at the head of EventCmd_f9 (C0/B8BA), 8 bytes: at 50 Hz, branch to C0/B8C2.
