Sound Hacking/Sharp X68000

These are only applicable to MAME unless stated otherwise.

Simple Triggers

File swapping

MAME and XM6 2.05 can be used here.

Lenam: Sword of Legend

Lenam: Sword of Legend uses a modified version of OPMDRV with a PCM packer (P.X), LZSS-compressed MML files(.MUS), and sound bank files(.SND) for the internal sound system.

The majority of the songs are stored in the System disk, while the Opening (oping.mus) and Title(TITLE.MUS) songs are in the Opening disk uncompressed.

Some songs use a specific sound bank:

AKI2.SND users

• DAN
• END1
• TOWN1
• MAZE
• CAS
• IV1
• IV2
• IV3B
• IV4
• SLEEP

OPING.SND users

• TITLE
• OPING
• OVER/LM9
• LM1
• LM2
• LM4
• LM6
• LM8

Users of neither

STOP

Note: It's important that you don't swap out the SLEEP.MUS file, or the game will not start.

Note: The driver is buggy, so some songs will not play correctly at certain sections. Thus, I've provided a save file where you can easily swap between two different songs (MAZE.MUS and TOWN1.MUS).

Pitapat

Pitapat uses the PMD x68k driver and plays the loading song (PP16.M) until the player starts the game. The song uses a separate sample bank, PIT_OMAKE.P. To correctly play the other songs (PP00.M~PP15.M), swap it with the other sample bank (PITAPAT.P).
