Yeah, I made gens crash, I was emulating something that I did very wrong.. the A7 got fucked up, and then.. In my opinion is a bug, if the game crashed, it's fine, but if the emulator crashes.. mmm..
Mm I don't remember it, and I don't have the code cause it was old version of what I'm doing,but I just have the rom. I think that I didn't touched the SP, it was something related with subroutines..., The SP begun going down until A10E10, then it crashed.
$A1xxxx is the register area, so I'm not surprised that setting SP there caused a problem. Of course, it shouldn't crash the emulator anyway! I'll look at this when I get around to integrating debugging support in Gens/GS.
It was fairly obvious from the screenshot. Regardless, this is probably a bug in the core Gens code, not in KMod's additions.
