failed 4mbit ram1 chip SD2SNES
« on: February 11, 2019, 12:14 PM »
Hi, looking for help with my SD2SNES please

After checking diagnostics on my sd2snes, I have a failed 4mbit ram1 chip and since redguy build gsu_08 on v1.8.0 this has been used for DSP ram so I cannot boot super FX games etc

Is this something that is repairable?

Another option would be to alter latest firmware to access the first ram0 chip instead like they did in builds gsu_07 v1.8.0 and earlier. Super FX support in this case is working.

So to use latest 1.9.0 firmware I either have to buy a new sd2snes, repair the second ram1 chip or alter ram access on current firmware to ram0 128mbit then all would be working fine!
Is this a possibility??

Where on the board is this chip located so I can maybe test the points of solder are good!?

Thoughts on best course of action?

Thanks in advance
