- 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 Claude-Session: https://claude.ai/code/session_013Vje3pEtpLHubqCGwCgoQX Co-authored-by: Claude Opus 5.5 <[email protected]>
