Flashcard based on HUC1a

Hello everyone, that will be my first post here smile

I got some spare cards based on HuC1a controller that I would love to turn into a DIY flash cardridges.
First issue that I see, is that I cannot trace the reset pin on HUC1a controller.

So her's the question, is it possible to create DIY  flashcard based on HUC1a?

The HuC1 is made by Hudson Soft. It's very similar to a mbc1 but it supports infared LED input/output.

So the pinout could be the same.

No, the pinout is completely different:

The reset pin should be 28, which is marked #RESET?#WP in the schematic, because of conflicting information, but it should be reset.

Good luck with your project smile
