I kinda gave up on playing on the mini and went back to my CRT and Duo. After messing with Bonk's Revenge, whatever is lagging (my LCD or the mini) was not fun for me. I do still use it to play Victory Run since the mini is conveniently located near my PC.
I managed a clear of Spriggian, but I did have to use one continue on the final stage. I used ROLFs' suggested blue/red weapon combo for most of the run. That worked pretty good, but I do still have some reservations about it. Mainly, when you drop a bomb or only have 2 orbs, it's not as effective versus my personal fav of yellow/green which maintains a decent fire power with only 2 orbs. I will comment that red/blue is more effective on the 2nd half of stage two with those plants that strike out at you when you're close to them.
