   ROM scanning (both modes):
     Recursive scan of system directory for *_CONTROL.ROM and *.SF2/*.SF3.
     ref: dosbox_pure_libretro.cpp:1399-1410
     MT-32 requires matched pair: *_CONTROL.ROM + *_PCM.ROM (PCM name derived
     from CONTROL name by replacing CONTROL with PCM, preserving case).

     control, 524288/1048576 = PCM), not by name.

+  Sound Canvas: the scan also lists every file whose name ends in ROM1.BIN,
+  WAVEROM1.BIN excepted, as "Sound Canvas SC-55". Selected, the Nuked-SC55
+  driver opens it at exactly 32768 bytes, then ROM2, ROM2_ST, ROM_SM,
+  WAVEROM1, WAVEROM2 and WAVEROM3 beside it, spelled with the capitalization
+  and extension of ROM1.BIN. Each file fills the slot its size names. Byte 67
+  of ROM1 selects the model, SC-55mkII/SC-55st, SC-55/SC-155, CM-300/SCC-1,
+  JV-880 or SCB-55, and the sizes the other ROMs must have. The driver does
+  not open without ROM1 and ROM2.

   12 full control ROMs + 2 PCM ROMs supported (no split ROMs in this MUNT).
   TinySoundFont (tsf.h) for SF2/SF3 playback.
   No firmware entries in .info file — all MIDI files optional.
 
   DBP_STANDALONE build mode exists (same MIDI logic, different I/O layer).
