It's "Master Chu and the Drunkard Hu" by Joy Van (or Sachen), the Taiwanese title is "Dao Shuai".

Canonically mapper 133, though for this game, mapper 079 world work as well, since it only has 32 KiB of PRG ROM. In fact, this Milmar board looks just like an AVE NINA-003/NINA-006 board.

Man, this game has such a weird mapper for what is basically a CNROM game. The Mapper 11 version was much simpler.

I've never seen a mapper with "Analog Feedback Bits" that must be written correctly or the mapper chip runs hot.

You mean, the Sachen 3009 board with the strangely-wired Namco 108 clone? Yes, that was probably a dopey attempt at copy protection with built-in "chip burn-in" for dumpers that did not pay attention.

The mapper is not CNROM.
My comment was about how the actual requirements of the game (32K PRG, 32K CHR, CHR switched in 8K banks) could have worked as a CNROM game.
But this game is not compatible with CNROM as written.

sorry my noob question, the game on the pcb is master chu (mapper 11) so why use mapper 79 instead mapper 11?
I found NINA-06 pcb very similar to Milmar's pcb but they use 74LS174 instead 74LS175, this can be a problem? maybe will be necessary same rewring stuff?

US version of Master Chu is Mapper 11, Taiwanese version is either Mapper 133, or Mapper 79, same program works on both boards. That board seems to be Mapper 79, not 133.

But if you really wanted to mapper-hack a game to work on Mapper 79, I guess you could. To hack a CNROM game, you'd change the write address from 8000-FFFF to be 5F00 instead. Would need to fully playtest the game to verify that the mapper hack worked.

Ok, I will try some mapper 79 games. they are mostly on NINA-06 pcb that uses 74LS174 instead 74LS175, you think this will be a problem?
