Here's a list of forum users who were very friendly and helpful. All of these guys taught me valuable information that helped me create a lot of my mods. You can nicely ask any of these guys for help as they all know what they're talking about
Ziggy587 from the racketboy forum
Why Ziggy is awesome: He's very friendly and taught me a lot of great information regarding dumping of roms and building reproduction carts
Tiido Priimägi "TmEE" from the sega16 forum
Why Tiido is awesome: He taught me how to properly desolder surface mount chips. He created the amazing sega genesis model 2 crystal clear audio mod. He found me what chips to use to build my clock signal dividing circuit in my rgb nes. He found out the exact hardware specs on the different sega genesis everdrive flash carts. He's built all kinds of custom hardware and understands the hardware better than most people.
Robivy64 from youtube
Why Robivy64 is awesome: He came up with the idea of using a four pin crystal oscillator in superfx carts and was vey helpful when I asked questions. Thanks to his idea I designed an overclock circuit that works on all superfx carts.
