|
|
|
|
|
Beetle NGP is a fork of Mednafen's NeoPop module for Neo Geo Pocket
|
|
|
|
|
and Neo Geo Pocket Color emulation via libretro.
|
|
|
|
|
|
|
|
|
|
No external BIOS or firmware files are required. The core uses a
|
|
|
|
|
built-in High-Level Emulation (HLE) BIOS that is constructed at
|
|
|
|
|
runtime by bios_install() in mednafen/ngp/bios.c.
|
|
|
|
|
|
|
|
|
|
The HLE BIOS populates a 64KB array (ngpc_bios[0x10000]) with:
|
|
|
|
|
- A system call vector table at 0xFE00 (27 entries covering
|
|
|
|
|
clock, RTC, interrupts, font, flash read/write, comms)
|
|
|
|
|
- Each vector target contains an iBIOSHLE instruction (opcode 0x1F)
|
|
|
|
|
that traps into biosHLE.c for high-level handling
|
|
|
|
|
- A built-in system font (2048 bytes at 0x8DCF)
|
|
|
|
|
- A default interrupt handler (RETI at 0x23DF)
|
|
|
|
|
- An infinite loop at 0xFFFE as the idle entry point
|
|
|
|
|
|
|
|
|
|
The TLCS-900h CPU (main) and Z80 (sound) are both emulated in
|
|
|
|
|
software. Flash memory for game saves is handled internally via
|
|
|
|
|
flash.c without needing a separate firmware dump.
|
|
|
|
|
|
|
|
|
|
The only core option is ngp_language (english/japanese), which
|
|
|
|
|
controls the language flag passed to games. It does not affect
|
|
|
|
|
BIOS loading.
