Games Freeze on MD1 but not MD2

[Mamejay]

Hi everyone,

I have been playing around with my Everdrive cart and have found a few strange things happening when using a Megadrive1 console.
In Street Fighter the game will randomly freeze at any point. I have tried different roms and the same things happens. I recently got a MD2 console and tried it out on that but I do not get any game freezing.
This occurs on 2 different MD1's but not on my MD2.

Anyone having similar issues? Anyone know why this may be happening?

Thanks

I am running OS20
PCB is V2.2
Firmware is V9
I think I worked out the problem. I had done the 7/13mHz overclock mod. I am finding that since then in 7mHz the console is very flakey. The everdrive just started to only boot in 13mHz mode.
I added a 10mHz oscillator and have been running it on that now. Seems to be perfect.
Will let you know if anything else happens but looking good so far.
