iNES Mapper 199 is used for two kinds of Waixing boards:

  • A duplicate of INES Mapper 176. Such games can be detected by them writing $02 to $5FF3 to enable Mapper 176's Extended MMC3 Mode.
  • The Waixing FS309 circuit board, a TNROM-compatible board with 32 KiB of battery-backed PRG RAM, of which 12 KiB are mapped into CPU address space from $5000-$7FFF. Used by the following games:
    • 成吉思汗 (Chéngjísīhán), Waixing's Chinese translation of Koei's Genghis Khan
    • 風色幻想 (Fēngsè Huànxiǎng) / 湯姆歷險記中文版 (Tāngmǔ Lìxiǎn jì Zhōngwén bǎn) / 汤姆寻宝记 (Tāngmǔ Xúnbǎo jì); Waixing's Chinese translation of Square no Tom Sawyer
    • 吞食天地: 三国外传 (Tūnshí Tiāndì - Sānguó Wàizhuàn): Waixing's re-release of Capcom's 天地を喰らう II: 諸葛孔明伝 (Destiny of an Emperor II). Unlike the original 1994 Hong Kong release by an unknown publisher, this release uses one conventional 1 MiB of PRG-ROM.
  • The MMC3 clone used by this board supports more than 512 KiB PRG-ROM, necessary for that last game in the list.
  • The 8 KiB of CHR RAM are unbanked, and games do not initialize the MMC3's CHR bank registers to a contiguous 8 KiB block!
