This list is incomplete VT01 - plain famiclone? VT02 - banking scheme to access 32MB, Dual APU with PCM support VT03 - above + 4bpp sprite / bg modes, enhanced palette VT08 - ? VT09 - alt 4bpp modes? VT16 - ? VT18 - ? VT33 (?) - used in FC Pocket, dgun2573 Adds scrambled opcodes (XORed with 0xA1) and RGB444 palette mode, and more advanced PCM modes (CPU and video working, sound NYI) VT368 (?) - used in DGUN2561, lexcyber Various enhancements not yet emulated. Different banking, possibly an ALU, larger palette space VT36x (?) - used in SY889 Uses SQI rather than parallel flash Vaguely OneBus compatible but some registers different ($411C in particular) Uses RGB format for palettes Credit to NewRisingSun2 for much of the reverse engineering same chipset used in Mogis M320, but uses more advanced feature set. (more) VT1682 - NOT compatible with NES, different video system, sound CPU (4x main CPU clock), optional internal ROM etc. (will need it's own driver) todo (VT03): APU refactoring to allow for mostly doubled up functionality + PCM channel *more* todo (newer VTxx): new PCM audio in FC Pocket and DGUN-2573 add support for VT368 (?) in DGUN-2561 and lexcyber add support for the VT369 (?) featurs used by the MOGIS M320 todo (general) Add more Famiclone roms here, there should be plenty more dumps of VTxx based systems floating about. Make sure that none of the unenhanced sets were actually sold as cartridges instead, there is a lack of information for some of the older dumps and still some dumps in nes.xml that might belong here. NON-bugs (same happens on real hardware) Pause screen has corrupt GFX on enhanced version of Octopus ***************************************************************************/ #include "emu.h" #include "includes/nes.h" #include "cpu/m6502/n2a03.h" #include "machine/bankdev.h" #include "video/ppu2c0x_vt.h" #include "machine/m6502_vtscr.h" #include "screen.h" #include "speaker.h" enum class vt_scramble_mode { NO_SCRAMBLE = 0, WAIXING = 1, PJOY = 2, HUMMER = 3, SP69 = 4 };
