I used MS-DOS 6.22 running in PCem to partition and format the image. So "fdisk" and "format d:". PCem itself detected the image as 16 heads when adding it to the emulated PC's IDE adapter.

It's the toolchain that comes with devkit pro. It's a GCC cross-compiler targeting PPC intended for homebrew development for various Nintendo devices (like GameCube.) Unfortunately, I don't know which version of GCC is in use in this particular case. It's a buildbot that compiles a dosbox core for …

Yeah. The common image creation tools (like bochs or PCem) create images with that BPB, but they report to the user 16 heads. If I didn't look at the dosbox code, I wouldn't even know what the correct value is supposed to be.

Well, it's 16 heads: Copy code to clipboard 1 Creating hard disk image 'c.img' with CHS=20/16/63 (sector size = 512) But it only works if I lie and say that it's 32 heads using "-size" 😒

(This is with current SVN.) It is currently impossible to mount HDD images. A 10MB image for example created with bximage from Bochs using defaults and formatted with DOS 6.22 fails the sanity check in drive_fat.cpp: /* Sanity checks */ if ((bootbuffer.sectorsperfat == 0) || // FAT32 not implemented …

For the fluidsynth 2.1 support that I've added to a libretro dosbox core I'm currently working on, having fluidsynth output audio is not necessary. Instead you can make it render audio directly in the dosbox mixer buffer using fluid_synth_write_s16(). I added an FSYNTH dos mixer channel (like the …

the 4-6 scaler patch should be easy to repair. Maybe one of the next commits will make it possible to apply again, as is. It's probably the partial 4x4 scaler implementation that went into the commit (that broke it), as my code contains more changes than the part that I committed. It's no secret …

You don't need "loopmidi" (whatever that is). You just load SCVA in MIDI Player. Then configure Midi Player to use "MIDI Through Port-0": https://i.imgur.com/S7zqCaL.png If you run " aconnect -l" in a terminal, you should then see something like: $ aconnect -l client 0: 'System' [type=kernel] 0 ' …

Please don't use that. It's an old version of fluidsynth You mean fluidsynth 1.1.6? And are you aware that I'm currently using even older version of fluidsynth? OK, do you know any better option? You can build a minimal version of Fluidsynth (2.1.0 currently) that does depend on audio drivers or …

Yeah, that's normal. It doesn't print anything, it just loads itself into memory and stays there. Also, do you actually need gatefix.com? The starting room ("Your Quarters") music plays fine for me after the intro with current SVN dosbox.

Nevertheless, it works and it's just as you said: It is more trivial to redirect output into dosbox mixer than compile operational FluidSynth library. At least under MinGW enviroment. There is a lightweight version of FluidSynth just for this purpose: FluidSynth-Lite Please don't use that. It's an …
