So today I get home from work and in the mail box waiting for me is a nice shiny new unibios 4.0, since my NeoBiosMasta came a few days ago I figured it would be a good time to pull the motherboard out and get to soldering. The NeoBiosMasta made the job so easy it only took about 10 min to get everything hooked up and back together. I took the motherboard back to the cab and plugged in good old Real Bout 2 and it booted up as normal, I held ABC and the unibios menu came up...great it works! I figured it would be a good idea to put a little hot glue over the solder points as extra strength. I power down the cab, take the game out, unhook the jamma harness and take the mother board back to the bench for a little glue. I put a few dabs of glue on the board and head back to the cab hoping to enjoy the new power my neo-geo holds! But instead I was greeted with this mess.View attachment 50154 After a few seconds of seeing that it came up with thisView attachment 50155 I tried turning it on and off cleaning the whole mother boards etc. Some times it would show the jumbled screen some times it wouldn't, sometimes it would give ram errors and some times it would give the illegal instruction screen. Some times it would let me boot in AES mode but nothing but a black screen would come up and if I held ABC to pull up the menu it would flash the menu but it wouldn't stay up or let me access it but ABCD would always let me pull up the memory card menu. It all seems so random, anyone have any ideas? it seems far fetched that a little hot glue would mess things up or blow up the ram. Here are a couple more screens that come up when booting.
If anyone has any ideas I would greatly appreciate it, or if you think its shot and time to get a new board that would be good to know too instead of pulling my hair out trying to figure it out.
