- Driver, SCU (DMA, interrupts, timers, DSP), SMPC, MINIT/SINIT, EEPROM
and the protection chips as current MAME; the current MAME sets.
- VDP1/VDP2 video as current MAME's (one stvvid.c), with exact speedups:
partial redraw of the rotation plane cache, rotation copy, sprite
passes, window evaluation once per line.
- SH-2 recompiler on the bundled sljit (x86, x86-64, ARM32, ARM64; the
"SH-2 Dynarec" core option, off by default): blocks with chaining,
page tables for direct memory access, memory handlers called from the
blocks; the SGL idle loop is skipped exactly; context switch by
pointer. Same output as the interpreter on all the sets.
- "ST-V Threaded Video" core option (off by default): the screen drawn
in strips by 2-4 threads (libretro-common rthreads, where thread-local
storage is native), same output.
Two more sets of Zen Nippon Pro-Wrestling Featuring Virtua, both on the
Taiwan BIOS (the core selects it):
- znpwfvt: All Japan Pro-Wrestling Featuring Virtua (Taiwan), as in
current MAME.
- znpwfve: English translation (bootleg) on the Taiwan program, with the
graphics the English mode left in Japanese redrawn; the ROMs are built
from the original ones by https://github.com/zanac/znpwfvt
