Unscrew MD motherboard

[monomaniacpat]

Hello,


I'm trying to perform a region mod on my MegaDrive 1. In order to drill a hole for the switches, I want to remove the motherboard from the lower half of the case. However, I seem to be having some trouble doing so. I have unscrewed all the screws I can find and it is stubbornly refusing to come loose.


Is there a knack to this? Or are there some hidden screws? Or have I just unscrewed too many screws!?


Any help or pictures would be helpful.


Please and thank you,


mono.

Argh. Worked it out: had to unscrew the cartridge slot!
