If it's the second version you have the choice of having wormmon... If so... Those instructions are a tad different. (Games and map selection)
Nothing bad to worry of .... I have both although I have to find my instructions for them...
But if you need help I can help. (BTW... Share the info if you figure out how to digivolve them normally.............. Mine doesn't do that... vrsn 1 or 2.... of mine..............{and ya they've had 100% digi-power.....})
