I can put in a new battery prior to trade. If you have a copy and want to trade it, PM what you think is fair.do you know when battery was changed and how much $ Would you put in?
You need a 40 pin programmer that can do 27C4096 eproms, so a cheap TL866 programmer will do.0x466: 0000=Normal, 0001=SHOW VERSION
This enables Free Play, even in the Japanese version. SHOW VERSION appears on the region/title screen
There is a trick to enable freeplay on JP boards if you have a US ST. If you mount the US ST, then set it to freeplay, then remove the US board and replace it with a JP ST, it retains freeplay. I've done this before, but you have to keep the A and B boards together and never swap games or you'll lose the freeplay(on the JP board). I think I read this works b/c the settings are saved to the A-board.Yes you are correct. I am looking to just enable free play :
