Firstly, many thanks to everybody for all the work they do on these arcade cores.
I noticed a thread about Burger Time running very slow and have just had a go on Moon Cresta and that seems to be stupidly slow where it's possible clear a couple of waves pretty much from the centre screen without much movement to eithe the left or right, that should not be possible !
Anyway - just wanted to share - previously it had been working ok as I was able to get a high score on this and save ( thanks to recent high score support ), but playing today seemed very off.
This was from power on of the MiSTer, no previous code was loaded.
