Actually, it's been confirmed to have even a PS1/N64 level of power

conserning calculation power,its about SNES. but in terms of memory, it have far large space. we can use as large as SDmemory. unfortunately, array access is incredibly slow...

can u save games to sd card

so does it have N64 power or SNES power and what is the maximum space for a game or a level

smilebasic doesnt have polygon engine. it is difficult to make 3D speedy Game. so its about SNES,not PS1. programs and other data are saved on sd. in these days,it has several GByte.

Is the array access any Faster on new 3ds would it be good enough to make megaman x4 or x3 with?

I dont know megaman x3,x4. but if it use polygon,its difficult.

So I may be wrong about PS1 potential, I just said what I heard.
