Pin 31 needs to be tied to Vcc.
Pin 24 needs to be tied to Vss.
Pin 30 needs to be tied to one or the other, depending on how you programmed the 128KB of data into the PROM.
i try this . no success

i think need special rom for this mapper

Well, since zxbdragon didn't say either yes or no and this is a hobby stuff that can help many people if properly RE'd, I'm sharing the relevant pictures.
Hope I'm not doing anything wrong.
All credits for these photos go to the zxbdragon, so, many thanks to him!
