I have a consolized Neo Geo board but it isn’t working properly.
So you just want to take the parts off of your existing 2 slot and rework a working 2 slot board?
Is your current board repairable? (like is it just problems like corrupted sprites or bad sound or a calendar error, etc.) or is it just completely dead, with no picture? Is the battery section nice & clean or corroded? When’s the last time it was changed? (or is it still the factory original battery)
