notes: |
|
||
|
|
bsnes C++98 is bsnes v085 downgraded to C++98 for old compilers.
|
||
|
|
Performance profile only. is_experimental=true.

Firmware loading differs from newer bsnes versions:
|
||
|
|
- NEC DSP (dsp1/2/3/4) and Hitachi DSP (cx4) firmware loaded from
|
||
|
|
the SAME DIRECTORY as the ROM, not from system_dir.
|
||
|
|
- Path: dir(interface->path(Slot::Base, ".dsp")) + firmware_name
|
||
|
|
ref: snes/cartridge/markup.cpp:231
|
||
|
|
- interface->path() returns basename + hint
|
||
|
|
ref: snes/libretro/libretro.cpp path() method
|
||
|
|
- Firmware name comes from the game's XML/BML markup (root["firmware"])
|
||
|
|
NOT fixed names like dsp1.program.rom
|
||
|
|
- Files are COMBINED (program+data in one file), not split
|
||
|
|
ref: snes/cartridge/markup.cpp:243-244 reads promsize*3 + dromsize*2
|
||
|
|
|
||
|
|
.info has firmware_count=0 because firmware is loaded from ROM dir,
|
||
|
|
not from system_dir — RetroArch can't pre-populate them.
|
||
|
|
|
||
|
|
The core warns "NEC DSP firmware X is missing" if not found but
|
||
|
|
continues without the coprocessor (games using it won't work).
|
||
|
|
|
||
|
|
files: []
|
||
|
|
# firmware loaded from ROM directory, not system directory
|

|
|
# no files to declare for system_dir placement
