iNES Mapper 193 represents boards that use NTDEC's TC-112 mapper IC.

 Example Game:
 --------------------------
 Fighting Hero (Unl)
 War in the Gulf & (its Brazilian localization)
 
 Registers:
 ---------------------------
 Regs at $6000-7FFF = no SRAM
 
 Range,Mask:   $6000-7FFF, $E007
 
   $6000:  [CCCC CC..] CHR Reg 0
   $6001:  [CCCC CCC.] CHR Reg 1
   $6002:  [CCCC CCC.] CHR Reg 2
   $6003:  [.... PPPP] PRG Reg
   $6004:  [.... ...M] Mirroring
     0 = Vert (A10)
     1 = Horz (A11)

It's not known if any games exist that rely on being able to change mirroring at run-time; reportedly both War in the Gulf and La Guerra del Golfo have hard-wired vertical mirroring, and Fighting Hero expects horizontal mirroring and powers up in that configuration.

 CHR Setup:
 ---------------------------
 
       $0000   $0400   $0800   $0C00   $1000   $1400   $1800   $1C00

 PRG Setup:
