2 MVS 4 slot board 1 good one and 1 bad

I guys,

I end up buying another 4 Slot MVS board since my keeps giving me video ram error message. Now i got the one i have working. I was wondering if i should fix this second one or trash it. Any advice. Also were is a good place to buy cartridges since i am not a fan of kof 94, 95,96 since those are the games that came with it. also i was able to get the 100 in 1 board cartridge but don't really like that much since the sound is messed up on that F%$$ thing. Do you recommend to get the 2nd board fix or just sell it. Also i am want to buy more games but i was thinking of wanting to convert it to a MK3 cabinet but i might just buy another empty cabinet.

Post up the error or check my repair logs and you'll get the info you need on which chip is bad. Depending on the error code it could be surface mount or standard DIP style SRAM chips.
