No music in Bubble Bobble (bublbobl) #15

Closed vanfanel closed 8 years ago

vanfanel commented 8 years ago

There's no music in Bubble Bobble with the Mame2000 core. There is music on 0.37b5 and standalone mame4all. Built and tested on Raspberry Pi 1 (ARM).

This game uses YM3526 for music. Further investigation reveals that ifdef-ed code src/sound/fmopl.cpp depending on the BUILD_YM3526 define is being built, but the YM3812UpdateOne() and FM_OPL *OPLCreate() functions are not being called. emu_YM3812_sh_start() in src/sound/3812intf.c is responsible for calling OPL_Create(), and is not called either. The root of all this is in OPL_sh_start(), where the emulator choses to use emulated ym3812 or not, based on the options.use_emulated_ym3812 variable. So it can be easily enabled and, in fact, works great. The value to options.use_emulated_ym3812 is assigned in parse_cmdline() in src/libretro/config.c, which again is never called.

Hi, i'm using a Raspberry pi 2 with retropie 3.2.1 installed.

Can you please explain to me what i have to do, as plain as you can, so i can fix the music issue in bubble bobble?

Thanks a lot.

Hi, Slathman

All you have to do is build the latest mame2000 core from the latest source revision in this repo. Music will be fixed with that version of the core.
