98Fmplayer (beta)
PC-98 FM driver emulation (very early version)
If you are just annoyed by some specific bugs in PMDWin, patched PMDWin might have less bugs and more features than this.
Current status:
- Supported formats: PMD, FMP(PLAY6)
- PMD: FM, SSG, Rhythm, ADPCM, PPZ8(partially) supported; PPS, P86 not supported yet
- FMP: FM, SSG, Rhythm, ADPCM, PPZ8, PDZF supported
- This is just a byproduct of reverse-engineering formats, and its emulation is much worse than PMDWin, WinFMP
- FM always generated in 55467Hz (closest integer to 7987200 / 144), SSG always generated in 249600Hz and downsampled with sinc filter (Never linear interpolates harmonics-rich signal like square wave)
- FM generation bit-perfect with actual OPNA/OPN3 chip under limited conditions including stereo output when 4 <= ALG (Envelope is not bit-perfect yet, attack is bit-perfect only when AR >= 21)
- SSGEG, Hardware LFO not supported
- PPZ8: support nearest neighbor, linear and sinc interpolation
- ADPCM: inaccurate (actual YM2608 seems to decode ADPCM at lower samplerate/resolution than any YM2608 emulator around, but I still couldn't get my YM2608 work with the DRAM)
Installation/Usage (not very usable yet)
gtk
Uses gtk3, pulseaudio/jack/alsa
$ cd gtk
$ autoreconf -i
$ ./configure
$ make
$ ./98fmplayer
Reads drum sample from $HOME/.local/share/98fmplayer/ym2608_adpcm_rom.bin (same format as MAME).
win32
Releases: https://github.com/takamichih/fmplayer/releases/
Uses MinGW-w64 to compile.
$ cd win32/x86
$ make
Reads drum sample from the directory in which 98fmplayer.exe is placed.
Uses DirectSound (WinMM if there is no DirectSound) to output sound. This works on Windows 2000, so it is theoretically possible to run this on a real PC-98. (But it was too heavy for my PC-9821V12 which only has P5 Pentium 120MHz, or on PC-9821Ra300 with P6 Mendocino Celeron 300MHz)
