FC_MAPPER4

Overview

FC mapper4 modified 62256 to a wide-body chip, the components were changed to SMD, and used with kazzo to burn mapper4 game 512+512

Final Fantasy 3 is 1024+0 and cannot be used. Devouring World 2 The Legend of Zhuge Kongming is 640+0 and cannot be used.
Modify the width of the board to be less than 10x10 and lengthen the length of the gold finger.

I only tried games with dual roms, but I couldn’t find games with rom+ram.

Use the switch in the upper right corner to select the rom and ram of chr

After opening the game in the emulator, you can check the ROM information and you can see the mapper type and prg, chr size and whether chr-ram is used.

Select the switch state based on this information

There is currently no mapper4 format that can save the game. . .
