Games Freeze on MD1 but not MD2

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

 

will be good if you will say which pcb, firmware, os you use

 

Thanks for the reply. I will post up the version in the next 4 hours when i get home from work.

 

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.
