Feature Request => Midi for x68000 computer family request using MT-32 munt

Kelvfimer commented 6 months ago

Description

When setting up MT-32 Synth Emulator Munt as midi out Mame core breaks with Fatal error: Device MIDI Out image device load failed: Unspecified error and failed the execution of the content.

Same settings and set up work in regular mame build. On retroarch Windows and Linux same settings work on other cores such as PX68k or PC98

It happens in Windows and Linux retroarch Mame

Expected Behaviour

Be able to execute MT32 midi output and also SC-55 midi output as in regular Mame builds

Platform

Windows or Linux Retroarch with latest Mame version RetroArch 1.18.0 (Git fcd546b74c) === Build ======================================= CPU Model Name: 11th Gen Intel(R) Core(TM) i7-11370H @ 3.30GHz Capabilities: MMX MMXEXT SSE SSE2 SSE3 SSSE3 SSE4 SSE42 AES AVX AVX2 Mame https://github.com/libretro/mame/commit/ac9d0347f5d331eb49017cd599a5e63a668b4f22 Munt 2.7.0 https://sourceforge.net/projects/munt/ Windows 11 and Linux

Repro Steps

Download Retroarch Windows (it also happens on Linux Retroarch version)

mame_softlists_auto_media = "enabled"
mame_softlists_enable = "enabled"

MIDI support is entirely disabled in the core currently.

Thx @sonninnos for your prompt answer. So I will complete the issue. BTW is there any ETA for having MIDI support? Regular Mame has it

sonninnos commented 6 months ago

Someone needs to write the libretro wrapper for it, so closing the issue won't help with that, but perhaps rather edit the title to be more generic.
