I noticed that VGM files for Gradius III are not present on the archives, and I want to help by making the files. I checked the sound test from MAME and the game annoyingly automatically plays the next song after several seconds which prevents me from recording the full song. I have some hacking experience but I am totally unfamiliar with Gradius III's hardware and with MAME's debugging features, even. M1 plays the songs fine (or at least, I think so because I never heard the songs from an actual arcade machine so I have nothing to compare it to) but people say M1 is inaccurate compared to MAME so at least I want to do it with MAME.
Can someone guide me on what I should do to record VGM files of Gradius III from MAME?
Thank you in advance for any guidance
