There is a lot of improvement in the code of the microcontroller in the Multi STV cartridge. It currently takes a maximum of 2.5minutes to load the longest game. This will be reduced to about 30 seconds in a couple of days.
After that, the speaker will play the Wav file of our choice that is read from the micro SD Card.
Also I'm going to add the USB port, so that it will allow for updating the code of the ARM for future versions :))
It still only reads what is in folder \game, jumpers will be added very soon.
Hopefully next week, I'll post a vide showing how it loads and how to change game and after that I'll start taking payments.
