Great!!
I've put a 10K resistor between /CS and the Batery's diode.
The SRAM's Vcc poped up to 2.38v.
The cicuit ended like this:
Code:
10K
+--/\/\------SRAM /CS
| 1K
-Batt+--->|--+--/\/\---+--SRAM Vcc
| 1N4148 |
GND |
Console's --->|--+
Vcc 1N4148
Hope it's "undestandeable".
I just don't know how reliable it is, but seems to be enough.
Thank you Lidnariq!! You rock!!!
PS.: Is it me or this DSP-1 clone is finicky?
It took a while to start the game, all I was getting was the Nintendo logo and the boot sound.
At first I tought it was the clock generator, but them I found a broken track on the demux.
But even this wasn't enough to boot.
Curiously, I added a LED to the DSP-1's /CS line and it booted!!
WEEEEIRD!! I played for a while and removed the LED. It stayed fine.
Other day I just melted the solder on the crystal's pins and it booted.
I also needed to cut 2 pins for it to render the graphics fine.
These pins seemed to be already cut from the begining, and I tought it was someone trying to fix it before me.
I'll just assemble it and don't touch!!
