First off - thanks for the tutorial @Xrider , i recently purchased a Dreamcast from ebay and received a VA0 model and thought I would be stuck.

I was hoping you might have a higher res image of the 502 pads? I've removed both the 501 and 502 memory chips but i think i have lifted a pad on pin 31. Image

Not sure if this pin is connected to the footprint or the via on the other side of the footprint?
Hello @gl6171

First of all, thank you for your kind words and compliments, I’m glad the tutorial helped you with your VA0 Dreamcast modification. 🙂
Yes, this point is connected on both sides, as shown in the photo below.

thanks again. Another question sorry - in the image below i can see you have the reset pin (#1) on the MX29LV160TMC connected to a pad but you haven't mentioned it in the instructions? is this necessary?
